description: Manifest is an open-source LLM gateway for AI agents and agentic workflows, connecting them to any model provider
  through one OpenAI-compatible endpoint. It routes requests across subscriptions, pay-per-token, bring-your-own-key, local
  models and custom providers, falls back when providers are down, autofixes broken requests on the fly, and tracks every
  request, token and dollar for observability. It can be self-hosted (Docker image manifestdotbuild/manifest, code at github.com/mnfst/manifest)
  or used as a cloud service at app.manifest.build.

  name: Manifest LLM Gateway API
  description: OpenAI- and Anthropic-compatible proxy API of the Manifest LLM gateway. Clients point at the gateway URL, send
    `auto` as the model and routing picks the real model; documented endpoints are POST /v1/chat/completions, POST /v1/responses,
    POST /v1/messages and GET /v1/models, authenticated with a harness key (`Authorization Bearer mnfst_...`). Cloud base
    https://app.manifest.build; self-hosted default http://localhost:2099. No machine-readable contract is published.

  detail: Manifest documents its OpenAI/Anthropic-compatible gateway endpoints (/v1/chat/completions, /v1/responses, /v1/messages,
    /v1/models) only in markdown docs; app.manifest.build answers /openapi.json with its HTML app shell and /v1/openapi.json
    with 404.
