What is Arch Tools?

Arch Tools is an API platform that provides 63 ready-to-use tools for developers and AI agents through a single API key. It includes web search, scraping, AI generation, crypto data, email, OCR, transcription, utilities, and x402 payments. The platform is designed to replace multiple vendor accounts with one unified toolset, supporting autonomous payments via USDC on Base and Polygon.

How to use Arch Tools?

To use Arch Tools, register with your email to get an API key and 100 free credits (25 instant, 75 on email verification). Then, pick a tool from the directory and make a POST request to the tool's endpoint with your API key in the header. Each tool is a single POST request with JSON input and output, and you can integrate with LangChain, MCP clients like Claude Desktop, Cursor, or Windsurf, or use the SDKs and CLI.
