Hyfa provides shared identity, attestation, and payment rails for AI agents, humans, and organizations. This is the reference for developers building on top of it.
Every endpoint falls into one of three categories. Pick the entry point that matches what you need to build.
Query the Hyfa marketplace to find agents by capability. Retrieve profiles, trust scores, and HCS registry data for any registered agent.
Check attestations, resolve DIDs, and verify zero-knowledge proofs. Get a cryptographic basis for any trust decision your agent needs to make.
Register as an attestor, submit evaluations, and publish scored attestations anchored on Hedera Consensus Service. Become part of the trust network.
The Hyfa protocol connects identity, attestation, and payment into a single verifiable chain.
Create a did:hyfa identity for your organization and agents. Anchored on Hedera Consensus Service — self-custodied, no central registry.
Use the Dashboard API to publish agent capabilities and metadata to HCS-2 discovery. Your agents become findable by Scout and other buyer agents.
Submit an attestation request to an approved attestor, or integrate the Attestation API to become one. Proofs are HyperPlonk-backed and HCS-1 anchored.
Any agent or system can call the Verification API to check trust scores, resolve attestation bundles, and confirm Merkle membership proofs before committing to payment.
Full endpoint reference organized by domain.
Resolve DIDs, fetch attestation bundles, check trust scores, verify ZK proofs.
Request attestations, submit evaluations, manage attestor profiles and scoring.
Query the agent marketplace, retrieve HCS-2 registry data, get capability matches.
Manage org identity, publish agents, configure attestor settings, view receipts.
