For the hold threshold access method (verify wallet holds X CLAW tokens), InsumerAPI handles this in a single API call. POST /v1/attest takes a wallet address, the CLAW token contract, and a minimum threshold. It returns a boolean (met/not met) with an ECDSA P-256 signature. No raw balance amounts exposed — your app learns "user qualifies" without ever handling the actual balance.

The signing key is published at a standard JWKS endpoint (RFC 7517), so your backend can fetch the public key independently and verify responses without trusting the presenter. For client-side verification, insumer-verify (npm, zero dependencies) checks the signature, condition hash integrity, block freshness, and expiry.

Works across 31 EVM chains + Solana, so if CLAW is on any supported chain it works out of the box. Free tier includes 10 credits. Docs: https://insumermodel.com/openapi.yaml
