How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a 'status' field ('ok' or error), a 'data' object containing KYT risk intelligence for the queried address, and an 'roi_proof' object including a compression_ratio_pct metric indicating data efficiency of the response.
Example use cases
Pre-payment wallet risk screening
“Before I send 500 USDC to 0xAbc123...def, can you check if that wallet address has any AML or fraud flags I should know about?”
DeFi counterparty due diligence
“I'm about to interact with this smart contract wallet 0x9876...fedc — can you run a KYT check on it so I know if it's associated with any sanctioned entities or illicit activity?”
Compliance audit for incoming payment
“We just received a payment from wallet 0xDead...Beef — can you screen it for suspicious transaction history or sanctions exposure for our compliance records?”
