description: >-
  Restate is a durable execution platform for building resilient distributed
  applications, microservice orchestration, durable workflows, stateful
  services, and AI agents. Founded by Apache Flink and Apache Kafka veterans
  (Stephan Ewen, Igal Shilman, Till Rohrmann), Restate ships a single-binary
  Rust runtime that journals every step of handler execution so code survives
  crashes, restarts, and infrastructure failures. The platform exposes an
  Ingress API on port 8080 for HTTP invocation of services, virtual objects,
  and workflows (with idempotency keys, async /send semantics, and delayed
  invocations) and an Admin API on port 9070 for deployment registration,
  service introspection, invocation control (cancel, kill, pause, resume,
  restart, purge), subscriptions, and cluster health. Official SDKs target
  TypeScript, Java/Kotlin, Python, Go, Rust, and Ruby, with first-class
  integrations for AWS Lambda, Cloudflare Workers, Deno Deploy, Vercel, and
  Kubernetes (via the restate-operator). Restate Cloud is the managed
  offering with SOC 2 Type I compliance, enterprise SSO (Okta, Google
  Workspace, Azure AD), HIPAA BAAs, and an in-preview client-side journal
  encryption feature.

    name: Restate Admin API
    description: >-
      The Restate Admin API is the HTTP control plane for a running Restate
      Server, exposed by default on port 9070. It manages service deployment
      registration, lists and introspects services and handlers, controls
      invocations (cancel, kill, pause, resume, restart, purge), manages
      Kafka and event subscriptions, queries system state via embedded SQL,
      and reports cluster health and version. The Admin API is the surface
      the Restate CLI and Web UI drive, and an OpenAPI document for the
      running server is available at the /openapi endpoint.

    name: Restate Ingress API
    description: >-
      The Restate Ingress API is the HTTP data-plane for invoking services,
      virtual objects, and workflows running on Restate Server, exposed by
      default on port 8080. Requests follow the path conventions
      /{ServiceName}/{handler}, /{VirtualObject}/{key}/{handler}, and
      /{Workflow}/{workflowId}/run, with JSON bodies. Append /send for
      fire-and-forget invocations that return an invocation ID, pass a
      ?delay= parameter for delayed/scheduled invocations, and use the
      Idempotency-Key header for at-most-once semantics (responses are
      cached for 24 hours). The Ingress also brokers Kafka-event-driven
      handler invocations and exposes per-service OpenAPI documents at
      :9070/services/{ServiceName}/openapi.

    name: Restate Service Protocol
    description: >-
      The Restate Service Protocol is the wire protocol Restate Server uses
      to communicate with handler endpoints implemented in any official SDK.
      It journals every side-effect (durable steps, RPCs, state reads/writes,
      sleeps, awakeables) so handlers can be replayed deterministically and
      resume from the exact step they were on when an infrastructure failure
      occurred. Implementations of this protocol are what make a language an
      official Restate SDK; the shared core lives in sdk-shared-core and the
      protocol definitions in the Restate Server source tree.
