How this service works
Set spending limits, budgets, approvals and audit trails on every AI agent wallet — Coinbase CDP, Privy, Turnkey, MetaMask. Non-custodial agent wallet management.
Output
A JSON object containing the tested URL, total number of conformance checks run, an array of individual check results (each with an id, pass/fail status, title, and detail string), a count of passed checks, and a timestamp of when the measurement was taken. Useful for understanding x402 protocol compliance at a glance.
Example use cases
Pre-launch wallet API compliance check
“Before I go live, can you run a full x402 conformance check on my agent wallet endpoint at https://mywallet.agentpayments.fi/api/pay and tell me how many checks pass and whether it returns a proper 402 payment envelope?”
Debugging a failing agent payment integration
“My Coinbase CDP wallet endpoint at https://agent402.tools/api/abc123 isn't processing agent payments correctly — can you run an AgentLedger conformance check on it and tell me exactly which x402 checks are failing and why?”
Auditing a third-party agent wallet for x402 support
“I'm evaluating a vendor's AI agent payment API at https://thirdparty.example.com/api/wallet — can you run an x402 conformance test on it and report back how many offers it has and whether it passes the 402 payment envelope check?”
Technical details
Endpoint
GEThttps://agentpayments.fi/api/conformanceWhen to prefer
Use this endpoint when you need to programmatically verify that an AI agent wallet API correctly implements the x402 payment protocol — especially before deploying agent wallets powered by Coinbase CDP, Privy, Turnkey, or MetaMask into production. Prefer this over manual testing when you want a structured, machine-readable conformance report with pass/fail details per check.
Side effects
- Target endpoint is unreachable or returns a network error — conformance report may show all checks failed
- Target endpoint does not implement x402 at all — all checks fail with descriptive detail messages
- Malformed URL provided — may return an error or empty result
- Target endpoint is rate-limiting the conformance checker — intermittent failures
- Endpoint behind authentication may not respond correctly to unauthenticated conformance probes
