How this service works
Screen wallets, analyze exchange accounts, and monitor transactions with regulatory context across 34 jurisdictions and 52 blockchains.
Output
Returns a JSON object with sender address, receiver address, chain, and a KYT risk result string indicating risk level (LOW/MEDIUM/HIGH), recommended action (ALLOW/BLOCK), and entity attribution for the from-address including entity name, type (e.g. EXCHANGE), and detailed verdict context.
Example use cases
Withdrawal compliance gate for crypto exchange
“Before we process this user withdrawal, run a KYT screen on the transaction from 0x28c6...1d60 to 0x21a3...5549 on the ETH chain and tell me if it's safe to allow or if we should block it.”
AML review of inbound DeFi payment
“We just received a large transfer on Ethereum from an unknown wallet — can you screen that transaction for AML risk and tell me whether the sender is linked to any known exchange or high-risk entity?”
Compliance audit trail for crypto custody platform
“I need to check the regulatory risk profile of this on-chain transaction on the ETH blockchain — give me the KYT risk verdict and entity attribution for both the sender and receiver addresses.”
Technical details
Endpoint
POSThttps://blockchainanalysis.io/api/x402/kyt-txWhen to prefer
Choose this endpoint when you need per-transaction KYT (Know Your Transaction) compliance verdicts with entity attribution on a specific blockchain, especially when operating across multiple chains (up to 52) and regulatory jurisdictions (up to 34). Prefer this over wallet-only screening when you need to assess both the transaction context and the counterparty risk in a single call. Ideal for real-time compliance gates on withdrawals, deposits, or DeFi interactions where a structured ALLOW/BLOCK verdict is required.
Side effects
- Unknown wallet address with no attribution data — may return LOW risk without entity name
- Unsupported chain identifier returns an error or empty result
- Transaction hash not found on the specified chain
- Malformed address input causes validation failure
- Rate limiting or payment failure via x402 protocol returns 402 error
