OpenAPI Specification

openapi: 3.1.0
info:
  title: Marqo REST Documents Telemetry API
  version: '2.26'
  summary: Open-source multimodal vector search engine REST API.
  description: 'Marqo is an open-source vector search engine that bundles index storage

    (Vespa) and embedding inference (Sentence Transformers, OpenCLIP, ONNX)

    behind a single FastAPI HTTP surface. The engine is reachable at

    `http://{host}:8882` by default and publishes its live OpenAPI schema at

    `/openapi.json` with interactive Swagger UI at `/docs`. The same surface

    is exposed by the hosted Marqo Cloud product at `https://api.marqo.ai`

    with bearer-token authentication.


    This profile is a hand-curated, best-effort companion spec covering the

    most-used operations across indexes, documents, search, embeddings,

    models, and telemetry. For the canonical, version-pinned specification

    of a deployment, fetch `/openapi.json` directly from the running engine.
