Insumer

Connects Claude to InsumerAPI for blockchain condition verification across 37 chains. Ships 26 tools covering token balances, NFT ownership, EAS attestations, Farcaster identity, and ratio checks for agent spend limits. Every verification returns an ECDSA-signed boolean with condition hashes and block metadata, no raw balances exposed. You can verify the signatures client-side with their insumer-verify package. Supports both JSON attestations and JWT format for standard bearer token workflows. Already running in production at AsterPay for ERC-8183 commerce trust scoring. Includes a setup tool that generates API keys without signup. Reach for this when you need cryptographically verifiable proof of on-chain conditions without trusting the API provider or exposing wallet details.
