Pre-sign risk check for AI agents: a green, orange or red verdict with reason codes before signing an EVM transaction, approval or EIP-712 signature, a Solana transaction (every instruction decoded, then simulated), an XRP Ledger transaction or an Algorand transaction or group. Checks the spender or recipient (including OFAC sanctions), the token itself (honeypot, impersonation, high tax) and, with origin, how old the requesting site is. POST /v1/check.
0 endpoints · $0.01–$0.01Check an x402 endpoint before paying it: go, caution or no_go with reason codes. Reads the endpoint's 402 challenge without paying it and checks every payment option (network, token, amount, whether the payout account can receive), the price against the seller's OpenAPI, the payout address against the OFAC sanctions list, and the endpoint's 30-day record in the x402 Trust Index. GET ?url=<endpoint>&max_usd=<budget>.
