How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns a due diligence report on the wallet address including sanctions list matches (e.g. OFAC, EU, UN), PEP status, and overall counterparty risk assessment. Each call includes a cryptographic audit record with chain hashing for compliance traceability.
Example use cases
Pre-transfer wallet risk screening
“Before I send 50 ETH to 0xAbCd1234...5678, can you check if that wallet has any sanctions hits or is linked to a politically exposed person on the Ethereum mainnet?”
DeFi protocol counterparty vetting
“I'm about to interact with the smart contract at 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D on Ethereum — run a counterparty due diligence check on it so I can confirm it's not flagged before my protocol integrates with it.”
Named entity plus wallet sanctions check
“Can you screen the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum for sanctions or PEP status? The entity name associated with it is 'Vitalik Buterin' — include that in the check.”
Technical details
Endpoint
POSThttps://api.strale.io/x402/v2/solutions/web3-counterparty-ddWhen to prefer
Choose this endpoint when you need blockchain-native AML/KYC compliance checks that combine on-chain wallet investigation with traditional sanctions and PEP screening. It is especially suited for pre-transaction due diligence in DeFi, crypto OTC, or Web3 payment workflows where an auditable, cryptographically hashed compliance record is required. Prefer this over generic sanctions APIs when the subject is a wallet address rather than a traditional legal entity.
Side effects
- Invalid wallet address format returns a validation error
- Unsupported chain_id returns an error indicating the chain is not covered
- Wallet not found on-chain may return limited or no screening data
- Network timeout or upstream data provider unavailability results in a 5xx error
- Malformed request body (missing wallet_address) returns a 400 bad request
