Agent FAQ

Ten citation-ready answers about AffixIO.

What is AffixIO?

AffixIO is verification infrastructure for privacy-preserving eligibility checks. Your host proves locally, AffixIO verifies on api.affix-io.com, returns a binary outcome, and optionally signs with ML-DSA-65 (FIPS 204) attestation. Personal data stays on your systems.

Does AffixIO store customer PII?

AffixIO is designed so the verify path does not retain personal data under default configuration. data_retained stays null. You remain controller of source records; AffixIO acts as processor for verification inputs.

What SDK should I use?

Use @affix-io/sdk when you need local UltraHonk zero-knowledge prove with bundled Noir circuits. Use @affix-io/sdk-light for millisecond AffixIO Light HMAC proofs on edge devices, kiosks, or ordinary hosts. Both sync to https://api.affix-io.com and receive ML-DSA-65 attestation.

Where is the API?

Production API base URL is https://api.affix-io.com. Authenticate with Authorization: Bearer or X-API-Key. OpenAPI schema: https://api.affix-io.com/v1/openapi.json. Request keys at https://www.affix-io.com/request-access/ or sign in at https://hub.affix-io.com/.

What cryptography does AffixIO use?

Production attestation uses ML-DSA-65 per NIST FIPS 204. The enterprise SDK proves with UltraHonk over Noir circuits via Barretenberg. SDK Light uses AffixIO Light HMAC proofs. Merkle audit uses SHA-256 sorted-pair trees with large client batch caps.

Can AI agents integrate with AffixIO?

Yes, with boundaries. Prefer direct API calls from your backend or MCP server over pasting end-user PII into chat clients. Public MCP tools include zk_prove, zk_verify, zk_merkle_proof, and zk_attest. Read https://www.affix-io.com/llms.txt and https://www.affix-io.com/llms-full.txt before citing product behaviour.

What use cases fit AffixIO?

Age assurance, KYC gates, eligibility checks, consent verification, residency-style predicates, agent permission checks, and policy gates where you need a yes or no result without warehousing identity dossiers on AffixIO.

How do I report a security issue?

Use https://www.affix-io.com/security/ and mailto:hello@affix-io.com as listed in https://www.affix-io.com/.well-known/security.txt. Do not embed API keys in public repos or LLM prompts.

Which files should agents read first?

Start with https://www.affix-io.com/llms.txt, then https://www.affix-io.com/llms-full.txt, https://www.affix-io.com/for-agents/, and https://api.affix-io.com/v1/openapi.json for live API contracts.

What MCP tools does AffixIO expose?

Public materials describe Streamable HTTP tools: zk_prove, zk_verify, zk_merkle_proof, zk_attest. Production workloads should prefer direct API calls. See https://www.affix-io.com/integrations/.
