Binary verify
Send an identifier and a circuit. You get eligible true or false. Optional signed material if you need it. data_retained stays null.
Verification infrastructure
Get the answer.
Keep the data.
AffixIO tells your systems yes or no. Proof runs on your side. We attest the result and keep an audit trail. Personal data does not come with us.

- Post-QuantumML-DSA-65 on every production sync

What you get
The pieces security and engineering teams actually connect.
Circuit policy
The circuit decides what you are checking: age, KYC, voting, health, finance, education. You pick the rule. Affix runs the check.
ML-DSA attestation
Production sync needs Affix ML-DSA-65 (FIPS 204) on the payload. That is the bar for a signed result you can keep.
Merkle audit
Digests land in an Affix-compatible Merkle tree. Leaves stay with their attestation so you can reconcile later.
Node.js SDKs
Two packages, one API. Pick the proof model that fits the device and the risk.
@affix-io/sdk
Enterprise SDK
Local UltraHonk zero-knowledge prove with bundled Noir circuits. Affix verifies, signs with ML-DSA-65, and anchors Merkle audit.
npm install @affix-io/sdk@affix-io/sdk-light
SDK Light
Millisecond Affix Light proofs for phones, kiosks, and ordinary hosts. Affix still attests digests with ML-DSA-65 and Merkle audit.
npm install @affix-io/sdk-lightHow it works
Your data stays put. Affix returns an attested outcome.
Prove on your host
Call @affix-io/sdk or @affix-io/sdk-light. You work with claim hashes, not raw records.
Verify and attest
Sync to api.affix-io.com with your API key. Affix returns an ML-DSA-65 attestation.
Keep an audit trail
Digests enter the Merkle trail. Offline queues flush when the network returns.
