For Developers
Build agent systems that implement APIS v2.1 for identity, authorization, trust-tier signaling, proof publication, and accountability.
Quick Integration Path
Get started with APIS v2.1 integration in four steps.
Choose Your Role
Determine whether your system will act as an issuer, principal, delegate, or verifier.
Integrate SDK
Use APIS-APP or SDK tooling to perform passport-init provisioning, credential validation, and verification.
Implement Flows
Follow passport-init, passport-renew, passport-revoke, mandate creation, signature verification, and revocation flows.
Test and Deploy
Validate against the published specification, reference proofs, and registry surface before promoting production issuers or delegates.
Core Concepts
Credentials
Agent Passports and Machine Passports are signed credentials that establish agent and machine identity once issued.
Profiles
An Agent Passport Profile defines the issuance class: subject type, agent class, issuer expectations, capabilities, restrictions, endorsements, lifecycle, and proof format.
Mandates
Authorization documents that specify what an agent can do, including scope and constraints.
Signatures
Cryptographic proofs that bind credentials and mandates, enabling verification.
Registry
Public verification records and proof artifacts that let verifiers inspect minted credentials, status publication, and reference proofs.
Trust Tiers
Verifiers can require physical TPM, attestable vTPM, confidential-compute evidence, namespace proof, software HSM, or development keys according to policy.
