Live x402 API with 18 settled payments — endpoint for settlement layer testing

[AmitabhainArunachala]

Hi! Your project is a settlement layer for AI agent payments with per-call billing. I have a live x402 paid API with 18 settled on-chain payments that could be useful as a real endpoint for your settlement system.

Live API: https://x402.167-172-95-184.nip.io

9 paid endpoints ($0.01-$1.00 USDC on Base):

• GET /price — $0.01 (BTC + ETH prices)
• GET /price/{coin} — $0.02 (16 coins)
• GET /portfolio — $0.05 (market snapshot)
• GET /opportunities/latest — $0.03 (revenue opportunities)
• GET /audit/x402 — $1.00 (x402 audit)
• POST /receipt/verify — $0.05 (receipt classification)
• POST /mcp/call — $0.05 (MCP gateway)
• GET /briefing/morning — $0.01 (daily briefing)
• GET /research/{topic} — $0.02 (research)

Payment details:

• Facilitator: Coinbase CDP (https://api.cdp.coinbase.com/platform/v2/x402)
• Network: Base mainnet (eip155:8453)
• Asset: USDC via EIP-3009 TransferWithAuthorization
• 18 settled payments verifiable on Basescan

Quick test:

curl -i https://x402.167-172-95-184.nip.io/price

Discovery:

• /.well-known/x402, /openapi.json, /llms.txt, /mcp/tools

Would a live x402 API with real settled payments be useful for your settlement layer's discovery or integration testing?

This is useful context for live x402 settlement testing. I’m also looking at how settlement layers discover/evaluate paid endpoints before paying. For this repo, would a benchmark signal like price range, route activity, and source confidence be useful when deciding which x402 endpoints to integrate?
