### Starting the API
Add `--extensions openai` to your command-line flags.
Add `--api` to your command-line flags.
* To create a public Cloudflare URL, add the `--public-api` flag.
* To listen on your local network, add the `--listen` flag.

* To use SSL, add `--ssl-keyfile key.pem --ssl-certfile cert.pem`. Note that it doesn't work with `--public-api`.
* To use an API key for authentication, add `--api-key yourkey`.
#### Environment variables
The following environment variables can be used (they take precendence over everything else):
| Variable Name | Description | Example Value |
|------------------------|------------------------------------|----------------------------|
| `OPENEDAI_PORT` | Port number | 5000 |
| `OPENEDAI_CERT_PATH` | SSL certificate file path | cert.pem |
| `OPENEDAI_KEY_PATH` | SSL key file path | key.pem |
| `OPENEDAI_DEBUG` | Enable debugging (set to 1) | 1 |
| `SD_WEBUI_URL` | WebUI URL (used by endpoint) | http://127.0.0.1:7861 |
| `OPENEDAI_EMBEDDING_MODEL` | Embedding model (if applicable) | all-mpnet-base-v2 |
| `OPENEDAI_EMBEDDING_DEVICE` | Embedding device (if applicable) | cuda |
#### Persistent settings with `settings.yaml`
You can also set the following variables in your `settings.yaml` file:
```
openai-embedding_device: cuda
openai-embedding_model: all-mpnet-base-v2
openai-sd_webui_url: http://127.0.0.1:7861
openai-debug: 1
```
### Examples
For the documentation with all the parameters and their types, consult `http://127.0.0.1:5000/docs` or the [typing.py](https://github.com/oobabooga/text-generation-webui/blob/main/extensions/openai/typing.py) file.
