x402
MimirAPI Sanctions Screener is a paid API for AI agents from mimirapi.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11).
Checks whether an EVM wallet address is sanctioned by querying the Chainalysis on-chain sanctions oracle contract, returning a true/false verdict with the oracle address for independent verification.

How this service works
Sanctions screen for an EVM wallet: one deterministic read of the public Chainalysis sanctions oracle contract. Call it mid-transaction before settling with an unknown counterparty — no account, no API key, one paid call returns sanctioned true/false with the oracle address for independent verification. Fail-closed: if the oracle is unreachable you get an error, never a false all-clear.
Output
Returns a JSON object containing the queried wallet address, a boolean `sanctioned` field (true if sanctioned, false if not), the on-chain oracle contract address for independent verification, the data source identifier, and a timestamp of when the check was performed. If the oracle is unreachable, returns an error rather than a false all-clear (fail-closed behavior).
Example use cases
Pre-settlement counterparty compliance check
“I'm about to settle a large USDC transfer to 0xAbCd1234abcd1234abcd1234abcd1234abcd1234 — can you run a sanctions screen on that address before I confirm the transaction?”
DeFi protocol onboarding screening
“We need to check if the wallet 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D is on any sanctions list before we allow it to interact with our protocol.”
Automated compliance gate in payment flow
“As part of my payment agent workflow, screen 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 against the Chainalysis oracle right now and fail the transaction if it comes back sanctioned.”
Technical details
Endpoint
GEThttps://mimirapi.com/v1/wallet/screen?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, trustless, on-chain sanctions check for an EVM wallet address before a financial transaction, with no account registration or API key management. It is ideal for autonomous agents executing payments to unknown counterparties in DeFi or crypto settlement contexts where compliance is required and fail-closed behavior is essential. Prefer over centralized KYC/AML APIs when you want independent verifiability via the on-chain oracle address and a pay-per-call model with no subscription overhead.
Side effects
- Oracle unreachable: returns an error rather than a false negative, enforcing fail-closed behavior
- Invalid address format: error if address is not a valid 0x-prefixed 40-hex-char EVM address
- Missing address parameter: 400-level error if the required `address` query param is absent
- Payment failure: x402 payment not completed results in access denied
- Network/RPC error contacting EVM node: returns error, not a permissive fallback
