Core Concepts

How AuthPI works: the resource model, the token model, and the architecture underneath.

• Global Identity Mesh How AuthPI's distributed architecture delivers global compliance and low-latency authentication without complexity.
• Issuers Learn what Issuers are, what they control, and how to configure them for your applications.
• Users Learn how Users work in AuthPI, including authentication, profiles, sessions, and lifecycle management.
• Introduction to AuthPI's Core Concepts Understand the key concepts of AuthPI, including issuers, portals and protocols.
• Organizations Learn how Organizations enable multi-tenancy, team management, and B2B features in AuthPI.
• Clients Learn how Clients represent your applications and enable OAuth 2.0/OIDC authentication flows.
• Agent Identities Agents are first-class non-human identities in AuthPI, distinct from users and API keys, with their own credentials, scopes, org memberships, and audit trail.
• Events Complete reference of all events emitted by AuthPI for webhooks, audit logs, and integrations.
• Credits & Billing Pay for AuthPI API usage on-chain with the x402 standard — no Stripe, no monthly invoice, just sign and ship.
• Multi-Org Tokens How AuthPI embeds active organization memberships in tokens, how selected-org tokens work, and how your resource server authorizes per org.
