https://chainverdict.xyz/v1/preflight/:addrGET /v1/preflight/:addr · x402 API by chainverdict
The check to run immediately before an agent sends USDC to an address it did not hard-code. Composite of OFAC SDN screening and on-chain address profiling, returned as clear_to_pay / caution / do_not_pay with the evidence behind it. 'clear_to_pay' means no configured negative signal fired — it is not an endorsement or a guarantee of counterparty legitimacy.
