We run Quackr, a virtual phone number platform that lets developers and individuals receive SMS verifications without exposing a real number. We just published our first inventory transparency report and the data was surprising enough that we thought the dev community would find it useful. The Numbers Right now, 97.6% of our entire virtual phone number inventory is actively rented. 66,214 out of 67,815 numbers assigned and in use across 15+ countries. Over 1,000 numbers available at any given moment but they move fast. That utilisation rate tells you something about how the market has shifted. Virtual numbers are no longer a niche throwaway tool. Developers, businesses, and privacy-conscious users are holding them long term. What Developers Actually Use Virtual Numbers For The obvious use case is SMS verification during testing. Spin up a number, verify an account in staging, move on. But that is not what drives the bulk of demand on our platform. The real volume comes from: Multi-account management — developers and businesses running multiple instances of platforms that require unique phone verification per account. Privacy layers in production apps — applications that need to verify users without collecting their real numbers. A virtual number sits between the user and the platform. Automated verification pipelines — this is where our API and MCP Server come in. If you need to provision numbers programmatically and retrieve OTPs without manual intervention, this is the use case we built for. Geographic flexibility — needing a UK number from Australia, a US number from Ukraine, or any combination that your real SIM cannot provide. The OTP Blocking Problem Something worth knowing if you are building anything that involves SMS verification: platform-level VoIP blocking has become significantly more aggressive over the past two years. WhatsApp, Telegram, Google, and TikTok all run detection on incoming verification requests. A VoIP number gets flagged and the OTP simp

Most API teams treat the contract as an afterthought: write code, generate a spec, then watch the two drift apart. Git-native API design reverses that flow. You treat the API contract as source code, version it in Git, and review every change the same way you review application logic. Try Apidog today This guide focuses on implementation discipline, not a single tool. You’ll design contracts in branches, review them in pull requests, and turn a committed spec into mocks, tests, and docs. The goal is simple: your Git history should also be your API history. If you already know what Spec-First tooling looks like and want the product walkthrough, read the companion piece on the git-native API workflow . This article stays focused on practice. What “git-native” means for API work Git-native means your API definition lives in your repository as a plain text file. Not in a proprietary cloud database. Not behind a vendor login. A .yaml or .json file sits next to your code and is tracked by the same version control system your team already uses. In many cloud-locked API design tools, the contract lives in the vendor’s backend. You edit through a web UI, and your repository only contains an export. That export can become stale, and your Git history no longer explains how the API evolved. The git-native model inverts that relationship: The file in main is the contract. Any GUI is a view onto that file. Branches, commits, pull requests, blame, and rollback all apply to your API surface. Mocks, docs, tests, and generated clients derive from the committed spec. A git-native setup has three core properties: The spec is a text file in the repo. Changes flow through normal Git operations: branch, commit, PR, merge. Downstream artifacts derive from the committed file, not from a separate database. Why design and develop APIs in Git You already trust Git with your code. Your API contract deserves the same treatment. 1. History When someone asks, “When did we add the cursor pagination

If you've ever built a REST API with Express, you've probably felt it. Middleware registration, type definitions, body parser setup, connecting Joi or Zod... the structure is simple, but the boilerplate is excessive. When I first saw Hono, I was skeptical. "Another Express clone," I thought. That changed when I actually ran it. Bottom line: Hono v4 is more than just lightweight and fast. TypeScript type inference flows naturally all the way to route handlers. Zod validation connects via a single official package. On Bun, response times are noticeably faster than Express. Everything in this post is based on what I ran in a sandbox in June 2026. Why Hono — Compared to Express and Fastify Understanding where Hono fits means answering three questions. Bundle size : Hono v4 core is about 12KB. Express is 58KB, Fastify is 77KB. The gap might not sound dramatic, but in edge environments like Cloudflare Workers or Deno Deploy, bundle size directly affects cold start time. Edge functions sometimes initialize a new runtime per request — smaller means faster first response. Runtime compatibility : Express is Node.js-only. Fastify targets Node.js by default. Hono was designed from the start to "run anywhere." The same code deploys to Bun, Deno, Cloudflare Workers, Node.js, and AWS Lambda Edge. TypeScript support : Express requires @types/express as a separate install, and properties added to req via middleware don't get type inference. Hono is written in TypeScript from the ground up, and the Hono<{ Bindings: Env; Variables: Variables }> generic gives you type-safe access to environment variables and middleware state. I'm not saying Hono is the right choice for every situation. If your team is deeply invested in Express, or you need a mature plugin ecosystem, there's no compelling reason to switch. But if edge deployment is the goal, or you want type safety from day one, Hono is the most convincing TypeScript API framework right now. Installation and First Server — Response in

pluckmd exists so an agent can pull blog posts into markdown, index them into a wiki, and generate interactive HTML to learn from. This post is about the first step, the part with no per-site code, because the design is the interesting bit. If you want the practical side, how I actually use it day to day, I wrote that up separately: https://dev.to/taisei_ide/how-i-use-pluckmd-to-read-blogs-with-an-ai-agent-1jpe It downloads articles from a blog without any per-site code. No handler for Medium, no handler for Substack, nothing keyed on a domain. Here's how that works. The core idea: treat extraction as data, not code. AdapterSpec Instead of branching on which site you're on, pluckmd resolves an AdapterSpec . It's a plain object that says which selector finds article links, what the URL pattern looks like, and how pagination behaves. interface AdapterSpec { listing : ListingExtractionSpec ; // how to find article links article : ArticleExtractionSpec ; // how to pull the body pagination : PaginationSpec ; // none | scroll | button-click | next-url | auto evidence : string ; } Because it's data, the same shape can come from a heuristic, an LLM, an agent, or a person typing it by hand. They all produce the same thing, and they all go through the same checks. Resolving it, cheapest path first cache -> heuristics (local, free) -> LLM (only if needed) Cache first, rechecked against today's DOM so a stale entry can't sneak through. Then local heuristics. The LLM only gets called when the heuristics aren't sure. Every result that works gets written back, so the second run on a site is basically instant. How the heuristics find an article list This part has no idea what site it's looking at. It takes every link, normalizes the path, and collapses the parts that vary into wildcards. / blog / my - first - post -> / blog /* / blog / another - article -> / blog /* / about -> / about Group by that shape. Any group with the same pattern repeated three or more times is a candidate f

Qwen3.7-Plus has appeared on Qwen's official research release page, with a release date of June 1, 2026. Chinese media covered the launch on June 2. The important part is not that Qwen 3.7 Plus can understand images. The bigger signal is that Qwen is pushing it as a multimodal agent model: vision, language, coding, tool use, and productivity workflows inside one task loop. For developers, the real question is simple: can it keep the same goal across software screens, web pages, screenshots, code, terminal output, and tool calls long enough to finish useful work? If your team is evaluating new agent models, keep the model shortlist in one place and compare quality, latency, cost, and failure modes by task: Compare AI models on WisGate . What Is Qwen3.7-Plus? Qwen3.7-Plus is a multimodal agent model from Qwen. Qwen describes it as an agent foundation that unifies vision and language. It builds on the Qwen3.7 text backbone, adds stronger vision-language capabilities, and keeps the agent-oriented strengths developers care about: coding, tool use, and productivity workflows. That makes it different from a basic image-question-answering model. The more useful use cases look like this: Read a UI screenshot and decide the next action. Combine web pages, docs, charts, screenshots, and text context. Turn a design or product screen into maintainable code. Use tools to verify results instead of only returning static answers. Move between GUI, CLI, browser, and code environments during one task. That is why Qwen3.7-Plus should be evaluated as an agent model first, not just as another chat model with vision support. Why This Release Matters More teams are moving models into longer workflows: read the request, inspect the code, run tests, check logs, fix the issue, verify again, and write the summary. The hard part is that real work is rarely text-only. Frontend bugs come with screenshots. Dashboards come with tables and charts. Debugging comes with terminal output, browser state,

The Model Comparison Problem Most AI model comparisons are useless for developers making real decisions. They benchmark on academic datasets that don't reflect production workloads. They test frontier capabilities that matter for 5% of use cases. They ignore latency, cost, rate limits, and API reliability — which are the things that actually determine whether a model works in your application. This comparison is different. It's focused on what matters when you're building something: how Grok and Gemini perform on the types of tasks developers actually encounter, what each model's API experience is like, and where the genuine tradeoffs lie. I'm deliberately not including benchmark scores. If you want MMLU numbers, there are plenty of leaderboards for that. This is about production utility. What Each Model Actually Is Grok (xAI) Grok is xAI's model family. The current production models are Grok-3 and Grok-3 Mini, with Grok-3 being the flagship. Grok has a large context window (128K tokens standard, with extended context available), real-time access to X (Twitter) data as a differentiating feature, and strong performance on reasoning-heavy tasks. The xAI API follows a familiar REST pattern and is broadly compatible with OpenAI SDK conventions, which makes migration straightforward. Grok's notable characteristics: Strong at structured reasoning and multi-step problem decomposition Real-time web access via the API (useful for tasks needing current information) Relatively generous rate limits compared to some competitors Less restrictive on certain content categories than some other models Gemini (Google DeepMind) Gemini is Google's model family, currently anchored by Gemini 1.5 Pro and Gemini 2.0 Flash. The defining feature of Gemini is its context window — Gemini 1.5 Pro supports up to 1 million tokens in production, which is genuinely useful for certain document-heavy use cases. Gemini also has the tightest integration with Google's ecosystem (Workspace, Cloud, Search)

If you've been writing Python for more than a year, you know the ritual. A new project. A fresh terminal. And then: pyenv install 3.12.3 pyenv local 3.12.3 python -m venv .venv source .venv/bin/activate pip install pip --upgrade pip install -r requirements.txt Six commands before you've written a single line of code. And that's if nothing breaks. Enter uv a single binary that replaces pip , virtualenv , pip-tools , pyenv , and pipx . Written in Rust. 10–100x faster than pip. And honestly, one of the most pleasant tools I've used in the Python ecosystem in years. Let's dig into it. What Even Is uv ? uv is a Python package and project manager built by Astral , the same team behind ruff , the linter that everyone switched to and never looked back. The goal is simple: be the Cargo for Python . One tool, one lockfile, no friction. It's a standalone binary with zero Python dependencies, which means it works even before Python is installed. Installing uv # macOS / Linux curl -LsSf https://astral.sh/uv/install.sh | sh # Windows (PowerShell) powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex" # Or via pip if you prefer pip install uv Verify: uv --version # uv 0.9.x The Speed Claim Is It Real? Yes. Embarrassingly so. Here's a timed comparison on Apple Silicon (Python 3.14): Operation pip / venv uv Create virtual env ~2 seconds 35 milliseconds Install FastAPI + deps (cold) ~12s ~1.2s Install with warm cache ~8s ~0.1s The warm cache case is where uv really shines it uses a global cache and hard-links packages into environments instead of copying them. If you've installed requests in any previous project, your next project gets it nearly instantly. Starting a New Project This is where uv feels like a completely different world: uv init my-api cd my-api That single command gives you: my-api/ ├── .git/ ├── .venv/ ← already created ├── .python-version ├── pyproject.toml ├── README.md └── main.py No separate python -m venv , no git init , no template c

“Did We Already Watch This?” — Building KindaSeen with FastAPI and Next.js A few months ago, my friends and I kept running into the same question whenever we talked about movies, dramas, anime, or variety shows: “Did we already watch this before?” Sometimes we remembered the title but forgot whether we had finished it. Other times, we completely forgot we had already seen it at all. That simple problem inspired me to build KindaSeen, a full-stack personal media repository designed to help users track and organize the media they’ve consumed in one centralized platform. The goal of the project was not only to create a useful application, but also to gain hands-on experience building a real-world full-stack system with modern web technologies. What KindaSeen Currently Supports User authentication with Supabase CRUD operations for personal media records TMDB-powered search functionality Watchlist system Favorites system Persistent PostgreSQL storage Dockerized backend deployment Separate frontend/backend deployment workflow Tech Stack Frontend Next.js React Tailwind CSS Shadcn/ui Vercel deployment Backend FastAPI PostgreSQL Docker Render deployment External Services Supabase Authentication TMDB API integration One of the main goals of this project was to simulate a more realistic production workflow by using a decoupled frontend/backend architecture instead of building everything inside a single monolithic application. In this article, I’ll share: Why I chose this architecture How I integrated TMDB into the application Challenges I faced during deployment What I Learned From Building KindaSeen Why I Chose This Architecture Instead of building a monolith using Next.js API routes, I decided to decouple the application into a Next.js frontend and a FastAPI backend. This decision was driven by three main factors: AI Compatibility & Future Proofing : While researching the job market, I noticed that most companies building AI products heavily rely on Python. By choosing FastA

Let me start with a confession: I'm a data scientist who's been burned by hype more times than I care to admit. When everyone told me "Model X is the next GPT-killer," I'd run my own benchmarks and find... well, let's just say the results were rarely as advertised. So when I started seeing claims about Chinese AI models catching up to (and sometimes surpassing) Western counterparts, I did what any self-respecting data nerd would do: I put them through my own rigorous testing pipeline. Over the past three months, I've run over 2,000 API calls across four major Chinese model families — DeepSeek, Qwen, Kimi, and GLM — using Global API's unified endpoint (more on that later). I tracked latency, token costs, output quality across multiple benchmarks, and even threw in some real-world tasks that mattered to me personally. Here's what I found, with all the numbers you'd expect from someone who still gets excited about statistical significance. The Testing Methodology (Because Anecdotes Aren't Data) Before we dive into results, let me be transparent about my approach. I ran each model on the following standardized tests: Code Generation : HumanEval (Python) and MBPP (multi-language) — 164 problems total Reasoning : GSM8K (math word problems) and MMLU-Pro (general knowledge) — 1,200 questions Chinese Language : CLUE benchmarks (text classification, NER, reading comprehension) — 3,500 samples English Language : LAMBADA and Hellaswag — 2,000 samples Speed : Average tokens per second over 100 consecutive requests with consistent prompt lengths I also tested vision tasks where applicable, but let's be real — Kimi doesn't support vision at all, and DeepSeek's implementation is... experimental at best. More on that later. All tests were conducted using the same global-apis.com/v1 endpoint, which normalizes API compatibility to OpenAI's format. This isn't an ad — I genuinely found it made my testing easier because I could swap models without rewriting code. The Big Picture: Pricing

Three Polymarket CLOB gotchas: 401, "invalid signature", and a cancel that does nothing Automating Polymarket with py-clob-client , I lost an embarrassing amount of time to three failures that aren't clearly documented anywhere. Here they are with the exact fixes, so you don't. 1. Your cancel returns 404 — because the endpoint isn't what you'd guess The intuitive DELETE /order/{id} returns 404 and your order silently stays open. The real endpoint is: DELETE /order body: {"orderID": "0x..."} # and the body is part of the signature Sign request_path = "/order" together with that body, then send the exact body. Miss this and your "canceled" orders keep resting on the book. 2. 401 Unauthorized that "should work" Authenticated calls need L2 HMAC headers, and the most common silent mistake is POLY_ADDRESS : it must be your wallet address , not the api_key. The reliable move is to let py-clob-client build the headers via create_level_2_headers from correctly-formed RequestArgs (method, request_path, body, serialized_body) — and make sure the serialized body you sign is byte-for-byte the body you send. 3. invalid signature = SignatureType / funder mismatch Nine times out of ten this is the SignatureType not matching how your wallet holds funds: 0 = EOA funder = your own wallet (holds USDC) 1 = POLY_PROXY funder = the proxy address (email/magic wallet) 2 = POLY_GNOSIS_SAFE funder = the safe address Signing as an EOA while pointing funder at a proxy (or vice-versa) yields invalid signature with no further hint. Bonus: the fill you read is wrong For a BUY , the shares you got are in takingAmount ; for a SELL , they're in makingAmount (takingAmount is the USDC). Read the wrong field and your accounting drifts, which then triggers resubmits and balance errors. I packaged the cancel/auth/fill helpers as a small MIT library: https://github.com/BlueWhale-Quant-Lab/polymarket-401-invalid-signature-cancel-order (For the harder production bits — reading /data/trades for reconciliation

A SaaS team adds “Pay with crypto” to checkout. The first test looks fine: create a wallet address, show a QR code, receive USDT, mark the order as paid. Then production starts. One customer sends the right amount on the wrong network. Another pays after the invoice expires. A third sends 99.80 USDT instead of 100 USDT. Support sees a transaction hash but cannot find the order. Finance sees funds received but cannot match them to an invoice. The backend receives the same webhook twice and unlocks the product twice. That is the moment crypto payment integration stops being a QR-code feature and becomes a payment infrastructure problem. This is the first Dev.to post from Cryptoway . We build crypto payment infrastructure for online businesses, and here we will share practical notes about crypto payment API design, invoices, payment webhooks, stablecoin payments, checkout flows, reconciliation and payment status handling. What is a crypto payment gateway? A crypto payment gateway is the layer between a business event and a blockchain transaction. The business event can be: a SaaS subscription invoice; an e-commerce order; a digital product purchase; a marketplace deposit; a service payment link; an internal billing event. The blockchain transaction is the customer sending BTC, ETH, USDT, USDC or another supported digital asset. The gateway connects the two. It creates a payment request, shows the customer what to pay, monitors the blockchain, updates the payment status and notifies your backend when something changes. In other words: a crypto payment gateway is not the blockchain itself. It is the operational layer that makes blockchain-based payments usable inside real products. Crypto Payment Gateway vs Wallet Address A wallet address is enough for a manual payment. It is not enough for a product that needs order tracking, support visibility and finance reconciliation. Area Wallet address only Crypto payment gateway Order matching Manual matching by amount, address o

Most scraper demos lie by accident. They show the happy path: one URL, one clean page, one neat JSON object. Then the first real user tries a marketplace search page, a login wall, a JavaScript shell, a rate-limited product page, or a site that serves different HTML to every fetch path. The response still comes back as JSON, so everyone relaxes. That is the trap. A JSON response is not the same thing as a useful extraction. The failure mode agents hate AI agents do not just need scraped text. They need to know what happened. Bad extraction output looks like this: { "title" : "Example product" , "price" : "$29.99" , "availability" : "in stock" } That looks fine until you inspect the source and discover the page was a login prompt, a bot challenge, or a thin JavaScript shell. The extractor filled the schema because the schema was requested. Helpful. Like a smoke alarm that hums a little song while the kitchen burns. Better extraction output separates the data from the confidence and the failure class: { "status" : "failed" , "failure_type" : "login_required" , "confidence" : 0.94 , "extracted" : null , "evidence" : { "final_url_type" : "restricted_page" , "visible_content" : "login prompt" , "structured_data_found" : false }, "next_step" : "Use an authorised source, public item URL, feed, API, or sample HTML." } That is less flashy. It is also much more useful. The useful contract is not “scrape anything” “Scrape anything” is usually a warning label wearing lipstick. For agent workflows, the better contract is: Return structured data when the page provides enough evidence. Return a specific honest failure when it does not. Preserve enough metadata for the caller to decide what to do next. Never invent fields just because a prompt asked nicely. This matters for ecommerce, lead enrichment, price monitoring, competitor tracking, procurement, and internal research agents. If the agent cannot tell the difference between “product unavailable”, “page blocked”, “login require

Large language models (LLMs) understand and generate text from prompts. OpenAI exposes models through the Responses API . The official openai npm package is the practical way to call it from Node.js. This post covers common patterns beyond a single prompt string. Prerequisites OpenAI account Generated API key Enabled billing Node.js version 26 openai package installed ( npm i openai ) For Markdown output: marked , dompurify , and jsdom ( npm i marked dompurify jsdom ) Client setup Create a client with your API key (read from the environment in production). import OpenAI from ' openai ' ; const client = new OpenAI ({ apiKey : process . env . OPENAI_API_KEY }); The same SDK can target other hosts that implement a compatible API by setting baseURL and apiKey : const client = new OpenAI ({ apiKey : process . env . LLM_API_KEY , baseURL : ' https://your-gateway.example/v1 ' , }); Azure OpenAI uses AzureOpenAI instead. Many third-party gateways support Chat Completions only; the examples below use client.responses.* , so confirm your provider supports the Responses API (especially for tools like web search). Basic integration Pass a string as input and read output_text from the response. const response = await client . responses . create ({ model : ' gpt-5.5 ' , input : ' Write a one-sentence bedtime story about a unicorn. ' , }); console . log ( response . output_text ); System prompt Use top-level instructions for stable behavior (tone, format, role). They take precedence over casual wording in the user message. const response = await client . responses . create ({ model : ' gpt-5.5 ' , instructions : ' Reply in one short sentence. Use plain language. ' , input : ' Explain what an LLM is. ' , }); console . log ( response . output_text ); Few-shot prompting Pass prior turns as an input array with user and assistant roles, then the new user message. Keep task rules in instructions . const response = await client . responses . create ({ model : ' gpt-5.5 ' , instructions :
