## Changes things (5)

Creates or changes something that can be changed back. Claude Code: ask.

### `insumer_attest`

- The description's first verb is "evaluate": a word for a change.
- Findings: warn base64-blob, warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
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 of the wallet, such as a minimum token balance, ownership of an NFT, an attestation held or a registered agent ID; the type field on each condition lists the kinds available and the fields each one takes. Chains: EVM chains plus Solana, XRPL, Bitcoin, Tron, Stellar and Sui; Bitcoin, Tron, Stellar and Sui support token_balance only. The attestation is signed twice: ES256, with a kid identifying the key, and a post-quantum ML-DSA-65 signature (pqSig, pqKid). Each result includes evaluatedCondition, a SHA-256 conditionHash, and the block (EVM), ledger (XRPL, Stellar) or checkpoint (Sui) it was read at. An attestation expires 30 minutes after it is signed, or 5 minutes when it includes a delegation condition. Costs 1 credit (2 with proof: 'merkle'). An rpc_failure error (503) means a read did not complete and nothing was signed: retry, and never treat it as a no. Current chain and check counts: https://insumermodel.com/llms.txt On this hosted endpoint the call is paid from a shared daily allowance, so the caller is not charged; the credit cost above applies on the caller's own API key, and each result states the price on a key and by x402 pay-per-call.
```

### `insumer_batch_wallet_trust`

- The description's first verb is "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
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 across 29 chains in 14 dimensions with the optional Solana, XRPL, Bitcoin and Tron wallets; the signed conditionSetVersion (currently 2026-10-08) names the check list. Dimensions arrive in a fixed order, identical for every wallet in the batch: the base dimensions as listed, then any of solana, xrpl, bitcoin and tron that were switched on, in that order. 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, while a pay-per-call (x402) payment covers every wallet in the request. A wallet whose reads did not complete gets an error entry and no signed profile: retry that wallet, and never treat the entry as a no. Each profile lists every check, so the response is large; by default the text is a summary per wallet (profile ID, held / not held / not evaluated counts, and the checks held in each dimension, in the fixed dimension order; the account dimension's checks are present rather than held), and the complete signed profiles are returned unchanged as structuredContent. Set detail to 'full' on the call to get the complete signed profiles as text too. Profiles cannot be fetched again, so a later call signs fresh profiles and is charged again. On this hosted endpoint the call is paid from a shared daily allowance, so the caller is not charged; the credit cost above applies on the caller's own API key, and each result states the price on a key and by x402 pay-per-call.
```

### `insumer_check_discount`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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 unproven wallet gets; walletTerms gives the store's terms, and discountIfProven (when present) is what signing would get.
```

### `insumer_validate_code`

- The name "insumer_validate_code" says "validate": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `insumer_wallet_trust`

- The description's first verb is "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
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 176 checks across 29 chains in 14 dimensions; optional Stellar and Sui wallets let rows inside existing dimensions evaluate. Dimensions arrive in a fixed order: the base dimensions as listed, then any of solana, xrpl, bitcoin and tron that were switched on, in that order. The account dimension holds two rows per chain on Ethereum, Base, Arbitrum, Optimism and Polygon: contract code at the wallet address, and an EIP-7702 delegation there; a plain key reads false on both, and which contract is never named. Rows on a chain whose wallet is not supplied stay in the signed profile with evaluated: false. Every check is held or not held (present or not present in the account dimension), never a balance. The signed conditionSetVersion (currently 2026-10-08) names the check list that was run; log it, never reject on it. Returns per-dimension pass/fail counts and an overall summary: no score, no opinion. Designed for AI agent-to-agent trust decisions. Costs 3 credits (6 with proof: 'merkle'). An rpc_failure error (503) means a read did not complete and nothing was signed: retry, and never treat it as a no. Current chain and check counts: https://insumermodel.com/llms.txt On this hosted endpoint the call is paid from a shared daily allowance, so the caller is not charged; the credit cost above applies on the caller's own API key, and each result states the price on a key and by x402 pay-per-call.
```

## Only reads (5)

Looks things up and changes nothing. Claude Code: allow.

### `insumer_compliance_templates`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `insumer_get_merchant`

- The name "insumer_get_merchant" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `insumer_jwks`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `insumer_list_merchants`

- The name "insumer_list_merchants" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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).
```

### `insumer_list_tokens`

- The name "insumer_list_tokens" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```
