# FreeTier Agent API

> Pay-per-call data API for AI agents. No signup or API key: unpaid calls return HTTP 402 with x402 payment requirements (USDC on Base, eip155:8453). Pay, then retry with the PAYMENT-SIGNATURE (v2) or X-PAYMENT (v1) header. Every response cites its data sources. No personal data. Built with AI assistance by FreeTier Kits.

## How to pay (x402)
1. GET the endpoint without payment -> HTTP 402. The PAYMENT-REQUIRED header is base64 JSON (x402 v2) with accepts[0] = {scheme: exact, network: eip155:8453, amount (USDC atomic units, 6 decimals), asset: 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, payTo: 0x165Eb3dC3E98403ecB1141e90400F5e71806554B}. The JSON body has the same in x402 v1 format.
2. Sign the payment with an x402 client (@x402/fetch, x402 for Python, Coinbase agentic wallet).
3. Retry with PAYMENT-SIGNATURE (v2) or X-PAYMENT (v1). On success the response has PAYMENT-RESPONSE. If processing fails you get 4xx/5xx and the payment is not settled.

## MCP
Streamable HTTP endpoint: https://freetier-agent-api.pages.dev/mcp (POST JSON-RPC; tools/list, tools/call). Free tools return data; paid tools return the request and payment requirements.
