What the platform ships

Concrete capabilities teams use in production: signed allow or deny, client-side prove, post-quantum computing (PQC) attestation, and replayable Merkle evidence.

Open sandbox SDK docs Evaluate

Capability list

Each item is available through the public API, sandbox, or @affix-io/sdk.

Signed allow or deny

Binary eligibility outcome with cryptographic attestation on the payload.

PQC attestation

ML-DSA-65 aligned with NIST FIPS 204 for long-lived decisions.

Noir circuits

Predicate proofs for age, tickets, KYC outcomes, and agent scope.

Node.js SDK

Prove, verify, witness prep, offline queue, and gates on your host.

REST API

OpenAPI published. Circuit verify, health, and Merkle endpoints.

Merkle audit

Append-only decision digests without storing underlying PII fields.

Offline prove queue

Queue proofs when witnesses are not yet available, then resume.

Secure QR

Embed proof at issue time for scanners that verify locally.

Questions

Short answers for buyers and engineers mapping this page to AffixIO verification infrastructure.

Where is the full SDK reference?

https://www.affix-io.com/sdk/docs

Do features require AffixIO to hold PII?

No. Default verifier posture discards inputs after signing.

How do I try features live?

Use /sandbox/ or install @affix-io/sdk from npm.
