InsumerAPI

Wallet auth for developers and AI agents. Send a wallet and conditions, get a signed boolean, across 37 blockchains. No secrets. No identity-first. No static credentials. Access depends on what a wallet holds, right now.

Wallet auth is the primitive: read, evaluate, sign, keep. Condition-based access is the category.

POST /v1/attest takes a wallet address and up to 10 conditions: token balance, NFT ownership, EAS attestations, Farcaster, view calls, ratio rules, account code (plain key, EIP-7702 delegation, or contract) and agent standing (ERC-8004, ERC-7710). It returns a signed pass/fail attestation with id, pass, results (a met boolean per condition, with conditionHash, blockNumber, blockTimestamp), attestedAt and expiresAt. Boolean, not balance. Each result is signed twice, ES256 and a post-quantum ML-DSA-65 signature, and anyone can verify both against the public keys at /.well-known/jwks.json.

Wallet trust profiles (POST /v1/trust) return 155 signed checks across 27 chains in 10 dimensions, up to 176 with optional Solana, XRPL, Bitcoin and Tron wallets. No score, no opinion: signed evidence, organized by dimension.

Chains: 31 EVM chains plus Solana, XRPL, Bitcoin, Tron, Stellar and Sui.

Connect any MCP client to https://api.insumermodel.com/mcp. No install, no key: ten tools on a shared daily allowance, for attestations, wallet trust profiles, merchant and discount checks, and signing keys. Run mcp-server-insumer locally with your own key for all 27 tools.

Returns an insr_live_... key instantly, shown once, so save it: 10 free verifications plus 100 requests a day.

No key, no account. x402 moves the money. InsumerAPI checks the conditions. Call POST /v1/attest, /v1/trust or /v1/trust/batch without a key, get a 402 with the price, pay in USDC on Base, Polygon, Arbitrum, Arc, or Solana, and retry with the payment. The payer is charged only for a successful answer, and the payer sees the answer only after the payment settled.

Every result verifies against the published public keys, offline with a saved copy of them. insumer-verify checks the ES256 signature, the post-quantum ML-DSA-65 signature, condition hashes, block freshness and expiry. Same specification, same published test vectors, in JavaScript and Python.
