How this service works
X402 payment protocol demo for blockchain address label query and compliance risk screening. Powered by BlockSec MetaSleuth and Phalcon compliance APIs.
Output
Returns human-readable labels (e.g. exchange, mixer, scammer, DeFi protocol), entity name, risk classification, and compliance risk indicators for the queried blockchain address, sourced from BlockSec MetaSleuth and Phalcon datasets.
Example use cases
AML screening for incoming crypto payment
“Before I accept this payment, can you screen the sender's address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 for AML risk? I need to know if it's flagged as a mixer, scammer, or sanctioned entity before we proceed.”
Identify unknown DeFi counterparty address
“We just received a large transfer from 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D — can you find out what entity or protocol this address belongs to and whether it carries any compliance risk?”
KYC wallet verification for new user
“A new user wants to withdraw funds to 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B — can you check if that wallet address is associated with any known high-risk entity or is flagged for KYC concerns before I approve the transaction?”
