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' boolean and a 'result' object containing the requested data (OFAC screening outcome, rate information, or billing verification details), after a $0.013 USDC x402 micropayment is processed.
Example use cases
Sanctions screening for a transaction
“Check if this counterparty is on the OFAC sanctions list before we process the payment — go ahead and pay the micropayment fee to get the result.”
Live exchange rate lookup
“Get me the current USDC exchange rate via the x402 micropayment endpoint and return whatever rate data comes back.”
Billing verification for agent workflow
“Verify the billing status for this account using the x402 compliance endpoint and tell me if everything checks out — pay the USDC fee automatically.”
Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/donation001?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need pay-per-call OFAC screening, exchange rate lookup, or billing verification and are operating in an x402-compatible agent environment capable of making USDC micropayments on Base or compatible chains. Avoid if you need free or subscription-based compliance APIs, or if your agent stack does not support x402 payment headers.
Side effects
- Payment not included or invalid — returns HTTP 402 requiring payment
- OFAC screening data unavailable — result object may be empty or null
- Invalid or missing 'properties' parameter — may return generic or empty result
- Domain not reachable — connection timeout or DNS failure
- Repeated identical endpoint names across siblings suggest possible auto-generated stub — actual data fidelity uncertain
