## Documentation & README

# NanoTools — x402 pay-per-call API for AI agents

**44 tools. No signup. No API keys. Pure [x402](https://www.x402.org/) micropayments on Base mainnet.**

Agents pay per call with USDC ($0.001–$0.03) via the x402 protocol — the HTTP 402 flow is fully automatic
with any x402-capable client/wallet.
