Insumer

Evaluate a list of 1 to 10 conditions against a wallet's on-chain state and return one signed attestation: a yes or no for each condition, never the balance. One call reads the chain for every condition in the list and returns a single attestation covering all of them, so conditions of different kinds and on different chains are combined in one signed result. A condition states what must be true o

List the compliance templates available for EAS attestation conditions. Each template carries pre-configured schema IDs, attester addresses, and decoder contracts for a KYC or identity provider (Coinbase Verifications on Base, Gitcoin Passport on Optimism), so a condition can name the template instead of raw EAS parameters. No authentication or credits required.

Generate a signed wallet trust fact profile for an EVM wallet: a curated set of presence checks organized into dimensions (stablecoins, governance, nfts, staking, institutional_stablecoins, tokenized_treasuries, stablecoin_deposits, wrapped_bitcoin, names, account): 155 base checks across 27 chains in 10 dimensions. Optional Solana, XRPL, Bitcoin and Tron wallets add their own dimensions, up to 17

Generate wallet trust fact profiles for up to 10 wallets in a single request. Faster than sequential calls. Each wallet gets an independently signed profile with its own TRST-XXXXX ID: 155 base checks across 27 chains in 10 dimensions (stablecoins, governance, nfts, staking, institutional_stablecoins, tokenized_treasuries, stablecoin_deposits, wrapped_bitcoin, names, account), up to 176 checks acr

Get InsumerAPI's public signing keys as a JWKS (JSON Web Key Set): an ECDSA P-256 key under its kids, followed by the ML-DSA-65 post-quantum key as RFC 9964 AKP entries. Signatures on attestation and trust responses verify against these keys. Match an entry by the kid (or pqKid) on the response, never by position; an unknown kid is unverifiable, not refuted. No authentication required.

Browse merchants in the public directory. Filter by accepted token, verification status. Returns company name, website, tokens accepted, discount info, and walletTerms (the store's terms with and without proof of wallet control).

Get full public merchant profile including token tiers, NFT collections, discount mode, verification status, and walletTerms: what the store gives a wallet with and without proof of control, so you can decide whether to sign before creating a code.

List the tokens and NFT collections listed in the Insumer registry. Filter by chain, symbol, or asset type. The registry is a directory, not the list of what can be checked: an attestation can check any token on a supported chain, and NFTs on EVM chains, Solana and XRPL, whether listed or not. An empty result means nothing is listed under that filter, not that the token is unsupported.

Calculate discount for a wallet at a merchant. Checks on-chain balances and returns tier and discount percentage per token, never raw balance amounts. Free: does not consume credits. Takes an EVM, Solana or XRPL wallet. An rpc_failure error (503) means a read did not complete: retry, and never treat it as not eligible. The check carries no proof of wallet control, so totalDiscount is what an unpro

Validate an INSR-XXXXX discount code. For merchant backends during ACP/UCP checkout to confirm code validity, discount percent, and expiry. Returns valid/invalid status with reason, and walletProven (whether the code went to a caller that proved control of the wallet). No authentication required, no credits consumed. Does not expose wallet or token data.
