+
+# Connect Open WebUI to DaoXE
+
+**DaoXE** is a multi-model multi-protocol AI API gateway. For Open WebUI, use the **OpenAI-compatible** Chat Completions path: set the connection URL to `https://daoxe.com/v1`, add your API key, and select a model ID from your account.
+
+:::note
+DaoXE is **not available in mainland China**. Model availability is account-scoped (there is no fixed public model list). Setup examples: [DaoXE-AI](https://github.com/seven7763/DaoXE-AI).
+:::
+
+## Prerequisites
+
+- An Open WebUI deployment with admin access to **Admin Settings → Connections**
+- A DaoXE account and API key from [daoxe.com](https://daoxe.com)
+- At least one model enabled for that key (check the DaoXE dashboard or `GET /v1/models`)
+
+## Admin connection (recommended)
+
+1. Open Open WebUI and go to **Admin Settings → Connections → OpenAI**.
+2. Click **Add Connection** (or the **+** icon under OpenAI API connections).
+3. Fill in:
+
+| Setting | Value |
+|---|---|
+| **URL** | `https://daoxe.com/v1` |
+| **API Key** | Your DaoXE API key |
+| **Model IDs (Filter)** | Optional. Leave empty to use authenticated `/models` discovery, or add specific model IDs from your account |
+
+4. Save the connection. If verification succeeds, models for that key appear in the model selector.
+5. Start a chat and pick a DaoXE model from the dropdown.
+
+:::tip
+Open WebUI verifies connections with `GET /models` using a Bearer token. DaoXE supports authenticated model listing for the key you provide. If your catalog is large, add a short allowlist under **Model IDs (Filter)** so the selector stays manageable.
+:::
+
+:::warning No trailing slash
+Use exactly `https://daoxe.com/v1` (no trailing slash). A trailing slash can break the `/models` path Open WebUI appends.
+:::
+
+## Direct Connections (optional)
+
+If the admin has enabled [Direct Connections](/features/chat-conversations/direct-connections) (`ENABLE_DIRECT_CONNECTIONS=true`):
+
+1. Go to **User Settings → Connections**.
+2. Add a connection with the same **Base URL** (`https://daoxe.com/v1`) and your personal API key.
+3. Save. Requests then go from the browser to DaoXE (CORS must allow your Open WebUI origin).
+
+## Notes
+
+- This path is OpenAI-compatible **Chat Completions** (`/v1/chat/completions`). DaoXE also exposes other protocols (for example OpenAI Responses and Anthropic Messages) outside this Open WebUI connection type.
+- Use model IDs from **your** DaoXE account only; do not hard-code a static third-party price/model list.
+- Prefer least-privilege keys for multi-user deployments.
