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.
