x402 examples — pay-per-call APIs for AI agents

Working examples for calling x402-gated HTTP APIs: your agent pays USDC per request on Base — no signup, no API keys, no subscription.

All examples run against x402.shizu.me (77 live endpoints, prices from $0.001/call): an OpenAI-compatible LLM gateway (/v1/chat/completions, /v1/embeddings, /v1/models), web search, a code sandbox, web scraping, live crypto/market data, verifiable randomness, and a prepaid off-chain metering rail for high-frequency loops (100+ calls/min, no per-call gas).

How x402 works

  1. Call any endpoint → the HTTP 402 response carries signed USDC payment requirements (price, asset, recipient).
  2. Pay — your x402 client signs the payment locally and retries automatically.
  3. Served — settlement is on-chain; you are only charged when the call succeeds. Errors and 4xx never settle.

Fund a wallet with a few dollars of USDC on Base, export its private key, and every example here just works.

JavaScript

npm install x402-fetch viem
export X402_PRIVATE_KEY=0x...   # wallet holding USDC on Base
node js/chat.mjs

Python

pip install x402 eth-account httpx
export X402_PRIVATE_KEY=0x...
python python/chat.py

Examples

Every route quotes its price on a free unpaid request:

curl -i https://x402.shizu.me/crypto        # → 402 + payment requirements
