  title: API Evangelist enhancements for USDOT ITS JPO Operational Data Environment (ODE) REST API
  version: 1.0.0
extends: openapi/us-dot-its-jpo-ode-rest-api-openapi.yml
actions:
  - target: $.info
    update:
      x-apievangelist-provider: us-dot
      x-apievangelist-api: us-dot:its-jpo-ode-rest-api
      x-apievangelist-verified: '2026-07-28'
      x-apievangelist-hosting: >-
        SELF-HOSTED. The `host` field is the literal placeholder "yourhostname" — there is
        no U.S. DOT-operated ODE instance. An operator (a state DOT, a research site)
        deploys github.com/usdot-jpo-ode/jpo-ode against its own Kafka cluster and its own
        roadside units. Apache 2.0.
      x-apievangelist-safety: >-
        This is a SAFETY-CRITICAL control surface. tim_put, tim_post and tim_delete write
        Traveler Information Messages onto physical roadside units; snmp_get and pdm_post
        talk SNMP to field hardware. Neither the spec nor the docs define an idempotency
        key, and tim_query and snmp_get declare a 408 Timeout with no safe-retry
        contract — a timed-out write may or may not have landed.
      x-apievangelist-event-surface: >-
        The REST API is the thin edge of a Kafka platform. 35 topics are declared in the
        ODE's own configuration; see asyncapi/us-dot-its-jpo-ode-asyncapi.yml.
