How this service works
X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.
Output
Returns a JSON object with a success flag and a result object containing the route's audit findings, including OFAC screening status, advertised payment rates, billing verification details, and any detected configuration issues for the specified x402 URL.
Example use cases
Pre-launch x402 route compliance check
“Before I go live, can you audit my x402 payment route at https://myapi.example.com/data/premium via GET on the Base network and confirm it passes OFAC screening and has the billing rates set up correctly?”
Troubleshoot rejected agent payments
“My AI agent keeps getting rejected when trying to pay at https://services.example.com/paywall — can you run an x402 audit on that GET endpoint on Ethereum and tell me what's misconfigured with the rates or billing verification?”
Verify third-party x402 endpoint before integrating
“I want to integrate with this x402 endpoint at https://partner.example.com/feed before I commit — can you audit it using GET on the Base network and show me its advertised USDC rates and whether it clears OFAC screening?”
Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/sellerops/audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to diagnose, validate, or audit an x402 micropayment route before integrating it into an agent workflow — especially when OFAC compliance verification and rate inspection are required simultaneously. Prefer this over manual inspection when you need a structured, machine-readable audit result with billing verification included.
Side effects
- Missing or invalid URL parameter returns an error or empty result
- Route does not respond with a valid 402 payment-required header, making audit incomplete
- Unsupported payment network enum value causes validation failure
- Target URL is unreachable or times out during audit
- OFAC screening data unavailable for certain wallet addresses
