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 compliance assessment including sanctions hit/no-hit status, risk flags for the wallet address and entity name, contract risk indicators if applicable, and a cryptographically hashed audit record for the check.
Example use cases
DeFi protocol counterparty screening
“We're about to swap tokens with wallet 0x7f3e...d91a on chain 1 via the USDC contract 0xA0b8...eB48 — can you run a pre-transaction sanctions check on them before we execute?”
Crypto payment compliance gate
“Before we pay out to the wallet 0xB2a4...f33c for entity 'Nova Ventures Ltd' on Ethereum, screen them for OFAC sanctions and any risk flags so I can approve or block the payment.”
Smart contract interaction risk check
“We want to interact with the contract at 0x1f98...4F1F on chain 137 — can you screen the contract and the counterparty entity 'Gamma Protocol' for compliance issues before we proceed?”
Technical details
Endpoint
POSThttps://api.strale.io/x402/v2/solutions/web3-pre-tx-gateWhen to prefer
Use this endpoint when you need a pre-flight compliance and sanctions screen before executing any blockchain transaction, especially in regulated or institutional contexts requiring an auditable trail. Prefer this over generic wallet analytics when you need both entity-level and address-level screening in a single call with a cryptographic audit record.
Side effects
- Invalid wallet address format returns validation error
- Unsupported chain ID returns an error or defaults to chain 1
- Entity name not found in sanctions databases returns clean status but may indicate data gap
- Contract address not relevant to the check may be ignored or return no additional signal
- Network timeout or upstream sanctions database unavailability returns error
