POST /v1/attest
unprobed
Signed attestation (ECDSA plus a post-quantum ML-DSA-65 companion) of on-chain wallet conditions across 37 chains: token balance, NFT ownership, EAS, Farcaster, view calls, ratio rules, and agent standing (ERC-8004 registration, ERC-7710 delegation validity with revocation proof). A verifiable boolean, never raw balances. Up to 10 conditions per pay-per-call request. Pay in USDC on Base, Polygon,…
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
