  title: WanAPIs Unified AI Models API
  version: '2026-05-27'
  summary: OpenAI-compatible AI gateway aggregating GPT, Claude, Gemini, DeepSeek and other LLM, image, video, and audio model providers behind a single key.
  description: 'WanAPIs (https://wanapis.com) is a developer-focused AI API gateway. Clients

    issue OpenAI-style requests against `https://api.wanapis.com/v1`; the

    platform routes them to the appropriate upstream model provider (OpenAI,

    Anthropic, Google, DeepSeek, Moonshot, Alibaba, xAI, Mistral, Stability,

    Midjourney, etc.) and applies per-project quota, metering, channel

    routing, and failover.


    This OpenAPI is **hand-authored** by API Evangelist. WanAPIs publishes no

    machine-readable spec — `https://api.wanapis.com/openapi.json` returns the

    admin dashboard. Operations included here are taken from

    https://wanapis.com/docs and https://wanapis.com/pricing and reflect the

    OpenAI-compatible surface plus the documented WanAPIs `/responses` and

    async task patterns. Request and response schemas mirror the OpenAI HTTP

    API by convention; consult the upstream OpenAI reference for full field

    semantics.
