  title: ZotGPT API (Deprecated)
  version: '1.0'
  summary: >-
    UC Irvine's first-generation, Azure API Management-fronted, OpenAI-compatible
    chat completions API. Deprecated in favor of the ZotGPT Gateway.
  description: |
    A faithful, documentation-derived contract for the single operation UC Irvine
    published for its first-generation developer API.

    PROVENANCE: GENERATED from https://zotgpt.uci.edu/services/api/ and
    https://zotgpt.uci.edu/services/migrate-azure-api/, which name the endpoint,
    the bearer-token auth, the model, and the base URLs verbatim. No
    machine-readable spec was retrievable — the Azure API Management developer
    portal at portal.azureapi.zotgpt.uci.edu gates its API definitions behind
    sign-in, and neither api.zotgpt.uci.edu nor api.azureapi.zotgpt.uci.edu
    resolves in public DNS.

    DEPRECATED: UCI has published a three-phase retirement — new signups frozen,
    a three-month self-migration window, then "all remaining Azure API keys
    disabled." See lifecycle/zotgpt-lifecycle.yml.
