+description: Configure BoostRail as a custom endpoint in LibreChat.
+---
+
+BoostRail is an OpenAI- and Anthropic-compatible API for text, image and video models from multiple labs. LibreChat connects to its OpenAI-compatible endpoint through `endpoints.custom`.
+
+## Get an API key
+
+Create an account at [BoostRail](https://www.boostrail.com) and create an API key in the [console](https://app.boostrail.com). Keys start with `br_`. Add the key to your `.env` file:
+
+```bash filename=".env"
+BOOSTRAIL_API_KEY=br_your-key-here
+```
+
+## Configuration
+
+Add the endpoint under `endpoints.custom` in your `librechat.yaml`:
+
+```yaml filename="librechat.yaml"
+    - name: "BoostRail"
+      apiKey: "${BOOSTRAIL_API_KEY}"
+      baseURL: "https://api.boostrail.com/v1"
+      models:
+        default: ["deepseek-v4.1-flash"]
+        fetch: true
+      titleConvo: true
+      titleModel: "deepseek-v4.1-flash"
+      modelDisplayLabel: "BoostRail"
+```
+
+To let each user supply their own key through the LibreChat UI instead of reading one from `.env`, set `apiKey: "user_provided"`.
+
+## Notes
+
+- With `fetch: true`, LibreChat loads the model list from BoostRail's `/v1/models` endpoint. The `default` list is used only if that request fails.
+- Models marked `byok_only` in the `/v1/models` response run on your own key for that lab, added in the BoostRail console. See [Bring your own key](https://www.boostrail.com/byok/).
+- Model ids and per-token prices are listed on the [BoostRail Models page](https://www.boostrail.com/models/). BoostRail's own setup guide for LibreChat is in its [docs](https://www.boostrail.com/docs/frameworks/#librechat).
