# API Anything

> Turn websites into plain HTTP APIs for AI agents to call directly.

API Anything captures how a website's frontend communicates with its backend and learns to replay those requests with new inputs. Instead of driving headless browsers with tools like Playwright, AI agents can execute plain HTTP calls over MCP, CLI, or TypeScript. It significantly speeds up execution time and reduces LLM token consumption.

## What it is for

- Replace slow headless browser automation with direct HTTP API calls for AI agents
- Extract structured data from websites lacking an official public API
- Provide reusable tool operations to coding agents via Model Context Protocol (MCP)
- Reduce execution latency and token costs during agentic web research tasks

## Features

- Traffic capture that identifies input variables from frontend network requests
- Model Context Protocol (MCP) server integration for AI coding assistants
- CLI and TypeScript interfaces for running operations directly
- Self-healing mechanism to refresh sessions and handle site layout changes
- Direct JSON responses over plain HTTP without loading full web pages

## Pricing

Open source. Free and open source under the MIT license.

## Why it was saved

- [@charles.zhengg, 8 October 2026](https://www.instagram.com/p/DeON0MOB5oi/): Eliminates the need for expensive official API plans and cuts AI agent execution time and task costs by roughly 50% compared to driving a headless browser.
