How this service works
Screen one address against sanctions and scam blocklists — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object indicating whether the check succeeded (ok: true), the type of check performed (screen-sanctions), a proof receipt containing a transaction hash, USD amount charged, and a unique receipt ID, plus the timestamp of when the check was generated.
Example use cases
Pre-transaction compliance check
“Before I transfer USDC to 0xAbC1234567890abcdef1234567890abcdef123456, can you screen it against sanctions and scam lists to make sure it's safe?”
DeFi protocol counterparty vetting
“I need to check whether 0xDeAdBeEf00000000000000000000000000000001 is on any sanctions or scam blocklists — it's a counterparty address interacting with our protocol.”
User onboarding KYC wallet check
“A new user just submitted their wallet address 0x1111111111111111111111111111111111111111 — can you run it through the sanctions and scam screening before we activate their account?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/screen-sanctions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call sanctions and scam screening for individual Ethereum addresses without a subscription, especially in agentic workflows where compliance checks are triggered on-demand before transactions. Prefer this over full KYC providers when you only need address-level blocklist screening rather than identity verification, and when you want a cryptographically receipted proof of the check.
Side effects
- Invalid address format (not a valid 0x-prefixed 40-hex-character Ethereum address) — likely returns a validation error
- Payment failure — insufficient USDC balance or x402 payment not accepted
- Address not found in blocklist data sources — returns clean result but data coverage may vary
- Service downtime or upstream blocklist provider unavailable — may return 5xx error
- Stale blocklist data — sanctions lists may not be real-time and could miss very recently added addresses
