Authlete

Authlete is an API-first OAuth 2.0 and OpenID Connect backend service that provides a headless authorization-server engine. It handles the OAuth/OIDC protocol logic and token management so organizations can stand up standards-compliant authorization servers and verifiable-credential issuers without building the protocol layer themselves. Authlete separates the Management APIs (configure services and clients) from the Runtime APIs (power authorization, token, introspection, CIBA, device-flow, federation, and OID4VCI endpoints), and offers managed shared cloud, dedicated cloud, and self-managed deployment across US, Japan, Europe, and Brazil regional clusters. It supports advanced profiles including FAPI / FAPI 2.0, CIBA, PAR, Grant Management, OpenID Federation, Native SSO, and OpenID for Verifiable Credential Issuance, plus regional open-banking standards (Brazil Open Banking, Australia CDR). Backed by 500 Global.

Authlete publishes 21 APIs on the APIs.io network, including Authorization Endpoint API, CIBA API, Client Management API, and 18 more. Tagged areas include Company, Authentication, OpenID Connect, Authorization, and Identity.

Authlete’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 28 more developer resources.
