Open WebUI

Open WebUI API

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).
