  • Free x402 pre-payment check

    GET https://api.402xagent.com/v1/products/endpoint-spot-check?url=<endpoint> probes a public x402 endpoint once without paying it and answers pay, skip or recheck with a stable reason_code, the price quoted in its live 402 versus the listing, and an Ed25519-signed receipt. 5 free checks per client per UTC day (at most 25 per network); add &mode=dry-run for a free dry run that never approves a payment. Also the MCP tool endpoint_spot_check at https://api.402xagent.com/mcp.

  • Paid spot-check with full payment terms

    The same check after the free quota: HTTP 402, $0.02 USDC on Base via x402 (exact scheme, amount 20000). Never pays the target. Adds the full payment details to the verdict (the exact payment terms, pay_to and deadline); optional claimed_price, pay_to, network and quote turn a mismatch into skip or recheck. Rules and reason codes: https://402xagent.com/rules.json.
