insumer_acp_discount ~197
Check token-holder discount eligibility in OpenAI/Stripe Agentic Commerce Protocol (ACP) format. Returns coupon objects, applied/rejected arrays, and per-item allocations compatible with ACP checkout flows. The on-chain check is the same one behind INSR discount codes, wrapped in ACP format. Consumes 1 merchant credit.

insumer_attest ~897
Verify 1-10 on-chain conditions for a wallet and return a signed yes or no for each, never the balance. Condition types: token_balance, nft_ownership, eas_attestation (raw schemaId or a compliance template such as Coinbase Verifications or Gitcoin Passport), farcaster_id (IdRegistry on Optimism), evm_view_call (a single-address-argument view function returning bool), ratio_to_amount (balance >= multiple * amount), ratio_to_supply (balance / totalSupply >= minFraction, ERC-20 only), erc8004_agent (registered ERC-8004 agent on Base), and erc7710_delegation (a signed MetaMask-framework delegation from principal to agent is currently valid on Base; spend, target and call limits are reported as declaredLimits, not simulated). Chains: EVM chains plus Solana, XRPL, Bitcoin, Tron, Stellar and Sui; Bitcoin, Tron, Stellar and Sui support token_balance only. Responses are ECDSA-signed with a kid identifying the key and carry a post-quantum companion signature; each result includes evaluatedCondition, a SHA-256 conditionHash, and the block (EVM), ledger (XRPL, Stellar) or checkpoint (Sui) it was read at. proof: 'merkle' adds EIP-1186 storage proofs on supported EVM chains. Attestations with a delegation condition expire in 5 minutes instead of 30; a failed delegation result carries failReason. Costs 1 credit (2 with proof).

insumer_batch_wallet_trust ~141
Generate wallet trust fact profiles for up to 10 wallets in a single request. Shared block fetches make this faster than sequential calls. Each wallet gets an independently signed profile with its own TRST-XXXXX ID. Supports partial success: failed wallets get error entries while successful ones return full profiles. Costs 3 credits per successful wallet (6 with proof: 'merkle'); credits are charged only for successful profiles.
