Checked on GitHub.
Overview
API Anything records the request a site's page sends for two example inputs, turns what changed into parameters, and replays it later over plain HTTP, falling back to an in-page fetch or page execution if blocked. It runs as an MCP server over stdio, an HTTP/OpenAPI server, a CLI, a TypeScript library and a Python client. It ships 323 read operations across 114 sites and syncs learned operations through a shared catalog.
Who it is for: Agent builders who need site data where no public API exists
Strengths
- Tier 1 calls are one plain HTTP request, with no browser or account
- Learning uses no LLM; cookies are stored as references, not values
- Ships 114 sites and 323 read operations; setup connects Claude Code, Codex, Cursor and others
- setup --local-only keeps learning and calls on your machine with nothing shared
Weaknesses
- Covers only operations someone has taught it; the catalog is described as young
- Reddit and similar sites block plain HTTP; there is no CAPTCHA solving
- Benchmarks cover few sites, one model and a few runs
- No write operations bundled; writes are off by default
What it needs
- no GPU
- Needs Node.js >= 22.13, headless browser (for learning and tier 2/3 fallback)
- Models: MCP clients (Claude Code, Codex, Cursor, Claude Desktop, Gemini CLI, VS Code, Hermes), Vercel AI SDK, LangChain.js, OpenAI Agents SDK
Quick answers
Is api-anything open source?
