How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON object with a boolean 'matched' field indicating whether the name was found on sanctions lists, and a 'count' integer indicating how many sanctions list entries matched.
Example use cases
KYC compliance for new customer
“Before we onboard this new client, can you check if 'Vladimir Petrov' shows up on any sanctions lists?”
Crypto counterparty screening
“I'm about to send funds to a wallet — can you screen the name 'Reza Al-Mansouri' against international sanctions databases to make sure we're in the clear?”
Vendor due diligence check
“We're considering a contract with 'Dragon Phoenix Exports Co' — can you do a quick sanctions screen on that company name before we proceed?”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/sanctions-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call sanctions screening check with no account setup or API key required, especially in agentic or automated workflows using the x402 micropayment protocol on Base. Ideal for spot checks on individual names during KYC, AML, or vendor due diligence flows where you don't want to commit to a subscription-based compliance service.
Side effects
- Missing 'name' query parameter returns a validation error
- Name with special characters may need URL encoding
- No match found returns matched: false with count: 0 (not an error)
- Payment failure via x402 protocol results in 402 response before data is returned
- DuckDNS hostname may have intermittent availability compared to stable domains
