Agent Transaction Trust

json-repair-api-9ybv.onrender.com · 4 paid endpoints · listed 2026-10-27

Public, account-free preflight for an autonomous x402 payment. Validates the merchant's exact PAYMENT-REQUIRED challenge against the intended request, checks Base USDC payment integrity and public merchant/payTo risk evidence, and returns APPROVED, REVIEW or DENIED with signed proof. It does not grant spending authority: an APPROVED result means the transaction evidence is clear enough to proceed only if separate delegated authority also permits the spend.

Claim it for free with x402_provider_claim (sign with your payout address), and get an alert within minutes when it stops answering with x402_monitor_create ($5 for 30 days). Both work over MCP (https://logicnodes.io/mcp/v2) or POST https://logicnodes.io/v1/tools/<tool>.

Income is all USDC received by the provider's payout address on Base, whatever the source. Score: 0-100: 50 x share of checks in the last 72 h that returned valid x402 payment terms + 30 x min(1, log10(1 + USDC received in 7 days) / 4) + 20 x min(1, log10(1 + distinct payers in 7 days) / 3). A provider never checked scores on income only; income is all USDC received by its payout address on Base, whatever the source. JSON: /v1/observatory/providers/json-repair-api-9ybv.onrender.com
