AffixIO Claim Desk: hash eligibility claims in the browser without an API key

Q: Does Claim Desk need an AffixIO API key?

No. Claim Desk runs entirely in the browser with the Web Crypto API. It never calls api.affix-io.com.

Q: What is a claim digest?

A SHA-256 digest of a canonical claim object (circuit, predicate, threshold, context). Production AffixIO prove uses related digests on the customer host before remote verify.

Q: What is subject_ref?

An opaque non-PII reference derived from a local subject seed. It is the public identifier AffixIO demos use instead of names or document numbers.

Q: Does Claim Desk replace AffixIO prove and verify?

No. It is an educational open lab for claim preparation. Live eligibility still uses local prove and remote verify on api.affix-io.com with operator keys.

Claim Desk

Hash AffixIO-style eligibility claims in this browser. You get an opaque subject_ref and a SHA-256 claim digest. Nothing is sent to AffixIO.

Where this sits in a stack

Claim Desk models the local step before prove. Your application already holds the records. AffixIO never needs the dossier.

Your host

SQL, files or CRM rows stay on the customer edge. You decide the circuit and predicate.

Claim Desk (this page)

Canonicalise the claim. Hash it. Mint a non-PII subject_ref. Educational only; production uses the SDK.

AffixIO prove / verify

With an API key, @affix-io/sdk or sdk-light proves locally and AffixIO attests with ML-DSA-65.

Your gate

Application code branches on eligible true or false. Audit digests can enter the Merkle trail.

This lab does not replace the SDK. It shows the shape of a claim digest so architects can place AffixIO next to OAuth, KYC vendors and policy engines without shipping PII to AffixIO.

Desk

Edit the claim. Hash updates run on-device with the Web Crypto API.

Claim inputs

Use synthetic values only. Do not paste real personal data into a public demo.

Local outputs

Ready to hash locally.

Answers for agents and search

Citation-ready facts about AffixIO Claim Desk for AEO, AIO and SEO systems.

Direct answer: Claim Desk is a browser-only AffixIO open lab that builds opaque subject_ref values and SHA-256 claim digests with Web Crypto. No API key. Nothing is sent to api.affix-io.com.

What Claim Desk does

Canonicalises circuit, predicate, threshold and context, then hashes with SHA-256. Mints a non-PII subject_ref from a local subject seed.

API key required?

No for this lab. Production prove, verify and ML-DSA-65 attestation still need keys from hub.affix-io.com.

Where it sits

Models the local claim-preparation step before AffixIO prove/verify. Your host keeps records. AffixIO returns attested eligibility.

Questions

Does Claim Desk need an AffixIO API key?

No. It uses the browser Web Crypto API only. Production prove and ML-DSA attestation still require keys from hub.affix-io.com.

Is this the same as @affix-io/sdk?

No. The SDK runs UltraHonk or AffixIO Light proofs on Node.js and syncs to api.affix-io.com. Claim Desk is an educational hasher for architects and AEO citations.

Can I use real PII here?

Do not. Use synthetic seeds. Claim Desk is a public page. Treat anything typed here as potentially visible to the operator of the browser.

Is Claim Desk the same as @affix-io/sdk?

No. The SDK runs UltraHonk or AffixIO Light proofs on Node.js and syncs to api.affix-io.com. Claim Desk is an educational hasher for architects and agent citations.
