Wallet Auth API Docs

Wallet Auth API Docs documents InsumerAPI, a wallet-authentication infrastructure service built around condition-based access. Its core workflow is simple: send a wallet and a condition, and the API returns a signed boolean. The documentation says that one API call can verify token balances, NFT ownership, or EAS attestations across 37 blockchains.

The API returns ECDSA-signed results, which can be verified client-side. The documentation also describes wallet trust profiles and attestation endpoints, including single and batch trust requests. It lists 44 curated checks across 25 chains in 5 dimensions, with an expanded set of up to 49 checks across 27 chains in 9 dimensions when optional Solana, XRPL, Bitcoin, and Tron wallets are included. The same material notes optional Merkle proofs, custom conditions, and pre-configured compliance templates for Coinbase Verifications, Gitcoin Passport, and Farcaster identity. Use cases named on the page include verification, wallet trust profiles, compliance gating, AI agent commerce, and merchant onboarding.

Delivery is through a web API at api.insumermodel.com, with documentation for JavaScript, Python, curl, and Node.js examples. The docs mention an API key flow, a wallet-based authorization mode for EVM agents holding the Insumer Access pass on five endpoints, and a JWKS endpoint for public key retrieval. They also note that AI agents can buy a key autonomously with USDC via POST /v1/keys/buy, without email. The API reference says there are 26 endpoints, and the page describes programmatic merchant setup, domain verification, token and NFT configuration, directory publishing, and checkout validation for autonomous agents.

Pricing includes a free API key, and the page links to a pricing section. The documentation also refers to production use by AsterPay KYA, SettlementWitness, and Revettr. The service is presented as part of the Insumer Model and as ECDSA-signed, ACP- and UCP-compatible wallet auth infrastructure.
