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 the tool name ('kyt'), blockchain chain identifier, screened wallet address, a human-readable risk verdict (e.g. 'KYT risk: LOW · entity: Binance 14 (EXCHANGE)'), and a structured verdict object with entity classification and compliance details. Payment is confirmed via x402 protocol.
Example use cases
Pre-payment wallet compliance check
“Before we send 50 ETH to 0x28c61d60, can you screen that wallet for AML risk and tell me if it's linked to any exchange or flagged entity?”
DeFi onboarding due diligence
“A new user wants to connect their crypto wallet 0xABC123 on Ethereum — can you run a KYT check and tell me if they're high risk or sanctioned before I let them in?”
Exchange deposit address verification
“We just received a deposit from a Bitcoin address bc1qxyz — can you check it against your compliance database and tell me the risk rating and entity type so we can decide whether to freeze it?”
Technical details
Endpoint
POSThttps://blockchainanalysis.io/api/x402/kytWhen to prefer
Choose this endpoint when you need real-time, on-demand AML/KYT screening of a specific wallet or address before initiating or accepting a crypto transaction. It is especially suited for compliance-aware payment flows, DeFi onboarding, exchange deposit verification, or any scenario requiring a risk verdict with entity attribution across a broad set of blockchains (52 chains, 34 jurisdictions). Prefer this over batch analytics platforms when you need a fast, per-address decision with regulatory context baked in.
Side effects
- Unsupported blockchain — chain identifier not among the 52 supported networks returns an error
- Unknown address — wallet has no transaction history or entity attribution, resulting in an UNKNOWN entity classification
- Invalid address format — malformed wallet address returns a validation error
- Payment failure — insufficient USDC balance or x402 payment rejection blocks the call
- Rate limiting — excessive call volume may trigger throttling
