How this service works
Wallet sanctions check for a validated EVM or Solana address. Returns a direct verdict, recommended action, match evidence, source lists, and an explicit AML-scope caveat.
Output
Returns a verdict ('sanctioned' or 'not_listed'), a boolean is_sanctioned flag, the detected address format (evm or solana), a recommended_action ('block_and_review' or 'no_exact_match'), a human-readable summary with scope caveats, match evidence (name, sanctioned_at, listed_blockchain) if positive, the sanctions lists checked, a checked_at timestamp, whether the result was cached, and any limitations to be aware of.
Example use cases
Example prompt
“Before I send any funds, can you check if the wallet address 0x1234567890abcdef1234567890abcdef12345678 appears on any sanctions lists and tell me whether I should block the transaction?”
Technical details
Endpoint
GEThttps://wallet-sanctions.use.x402atlas.com/checkWhen to prefer
Use this endpoint when you need a fast, pay-per-call sanctions compliance check for a single EVM or Solana wallet address before executing a transaction, onboarding a user, or fulfilling a payment. It is ideal for agents that need lightweight AML/OFAC screening without a full compliance subscription. Prefer this over broader risk-scoring services when a binary sanctioned/not-listed verdict with recommended action is sufficient.
Side effects
- Missing or invalid address parameter returns a 400-level error
- Address string outside valid length range (32-44 chars) rejected
- Unrecognized address format (neither EVM nor Solana) may return an error
- Upstream sanctions list temporarily unavailable may cause 5xx error
- Payment required (402) if x402 payment header not provided or insufficient
- Cached result may be slightly stale for very recent sanctions designations
