Api Endpoint

InsumerAPI

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, account code (plain key, EIP-7702 delegation, or contract), and agent standing (ERC-8004 registration, ERC-7710 delegation validity). A verifiable boolean, never raw balances or code. Up to 10 conditions per pay-per-call request. Pay in USDC on Base, Polygon, Arbitrum, Arc, or Solana.
