I Run Claude Code on $0/Month: A Practical Guide to Free LLM APIs AI coding assistants are incredible — until the API bill arrives. If you've ever watched your Claude Code or Cursor usage tick upward and wondered whether there's a cheaper way, this guide is for you. The good news: in 2026, the free…
Did you know that an AI agent with live access to your Auth0 tenant can catch bugs that no static analysis ever would? I handed Claude Code a deliberately naive Flask app and the Auth0 MCP Server, and it discovered that my tenant was already rotating signing keys while my app only trusted the first…
Two questions every agent hits on day one of any integration: "Is this service even alive, and what version is it running?" — because the alternative is blindly POSTing to /v1/charge and getting a 404 back, which then triggers a 6-hour support ticket. The 10 conventional health/version endpoints (…
Two questions every agent hits on day one of any multi-URL workflow: "What's the actual final URL after all the redirects?" — because the link I was given is https://blog.example.com/post and the page I want to read is https://example.com/blog/post/2024/06/05/why-x402-matters , and if I don't walk…
Un atributo HTML y una pseudo-clase CSS jubilaron en los últimos años a buena parte de las librerías JavaScript que usabas para modales, menús desplegables y animaciones de cambio de página. Son APIs nativas del navegador : <dialog> , el atributo popover , el selector :has() y la View Transitions…
A single MCP server in front of one service is a solved problem: generate tools from the OpenAPI spec, run it over stdio or HTTP, done. At company scale the problem changes shape. A midsize platform team has forty services, each with its own spec, its own auth, its own staging and production hosts.…
Most APIs were designed for two consumers: a human reading documentation and code a human wrote once. An AI agent is neither. It discovers endpoints at runtime from a machine-readable description, fills in arguments by pattern-matching field names, retries automatically when something fails, and…
You made your first API request. Data came back. And it looks like this: json {"match_id":"match_50231","status":"live","minute":72,"home":{"name":"Manchester City","score":2},"away":{"name":"Arsenal","score":1}} A wall of braces, quotes and colons. You can sort of read it, but you are not sure how…
Email verification looks like a simple endpoint: accept an address, create a token, send a message, and return 202. In a real REST API, the difficult part starts when the client retries, two browser tabs submit together, or a worker delivers the same message twice. The reliable approach is to make…
A practical TypeScript guide to the App Store Connect and Google Play review APIs, with the gotchas I hit along the way. tags: ios, android, typescript, tutorial I make small iOS and Android apps, and for a long time I read reviews the slow way: open App Store Connect, scroll, open Play Console…
