How It Works

This MCP server exposes 22 tools backed by 3 x402-powered APIs. When an AI agent calls a tool:

The MCP server forwards the request to the appropriate API
The API returns a 402 Payment Required response with USDC payment instructions
With an x402-enabled client, payment happens automatically
The API returns the data

Note: Without an x402 payment client, tools will return payment instructions showing the cost and how to pay. To enable automatic payments, use the APIs directly with @x402/fetch and a funded wallet.

Payment

All payments are in USDC on Base (eip155:8453). Prices range from $0.01 to $0.25 per request.

No API keys. No subscriptions. No accounts. Just micropayments.
