ZotGPT (UC Irvine) Embeddings API

openapi: 3.2.0
info:
  title: ZotGPT Gateway Embeddings API
  version: '1.0'
  summary: UC Irvine's unified AI API gateway, on the Portkey API specification.
  description: 'A faithful, documentation-derived contract for the surface UC Irvine

    publishes for the ZotGPT Gateway.


    PROVENANCE: UC Irvine does not publish a machine-readable OpenAPI for the

    Gateway. This document was GENERATED from the operations, base URLs, headers,

    provider aliases, and model slugs named verbatim on

    https://zotgpt.uci.edu/services/gateway/ and

    https://zotgpt.uci.edu/services/gateway/clients/. Only surfaces UCI names in

    its own documentation are included. Request/response schemas follow the

    Portkey / OpenAI-compatible shapes that UCI points clients at; they are

    intentionally permissive rather than exhaustively enumerated, because UCI

    publishes no field-level reference of its own.


    NOT A UCI-OWNED HOST: the documented data plane is Portkey''s multi-tenant

    host. UCI tenancy is asserted by the workspace virtual key and the

    x-portkey-provider alias, both minted behind UCInetID.

    note: No anonymous OpenAPI/Swagger was retrievable from any ZotGPT host. Probes for /openapi.json, /openapi.yaml, /swagger.json, /api-docs, /docs and /v1/models against api.zotgpt.uci.edu all failed at DNS resolution; the Azure API Management developer portal at portal.azureapi.zotgpt.uci.edu returned 200 but gates its API definitions behind sign-in.
