Open WebUI API is one of 4 APIs that [Open WebUI](https://apis.io/providers/open-webui/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Chat, Models, Prompts, RAG, and Knowledge. The published artifact set on APIs.io includes API documentation and an API reference.

REST API exposed by a self-hosted Open WebUI instance. Endpoints cover chat completions (proxying upstream backends like Ollama or OpenAI-compatible servers), models, prompts, knowledge bases, files, RAG, users, auth, and tools. Authentication uses the Open WebUI session token or per-user API keys. The base URL is wherever you deploy Open WebUI (commonly http://localhost:3000/api/v1).
