# 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.

## 💳 Payment

x402 `ExactEvmScheme` on **Base (eip155:8453)**, payTo `0x4F568Bf0cE8537CBE7a0DAF1A43C955e0a648db9`,
facilitator `https://facilitator.openx402.ai`. Prices are declared per-tool in the discovery endpoints
(`x-price-usd` extension in OpenAPI).

## 🚀 Quick start with any x402 client

Point your agent at any tool URL from `llms.txt` — the first call returns `402` with payment requirements,
the client signs USDC, retries with `X-PAYMENT` header and gets the result.
