Hi -- I saw universal-crypto-mcp includes x402 payment tools like x402_pay_request and examples for paid APIs.
If it helps the examples, Satoshi API can provide a small live Bitcoin fixture:
- Free first call:
GET https://bitcoinsapi.com/api/v1/fees/recommended
- Paid x402 call:
GET https://bitcoinsapi.com/api/v1/fees/landscape ($0.005 USDC on Base)
- Discovery:
https://bitcoinsapi.com/.well-known/x402
- Agent context:
https://bitcoinsapi.com/api/v1/agent-context
The practical demo is: Should I send Bitcoin now or wait? An agent can answer for free first, then use the paid endpoint to test a real 402 challenge and retry when a wallet is available.
I can contribute a short docs/example PR if that would be useful. Not asking for a listing by itself -- the useful bit would be a runnable example for the x402 payment path.
