OpenAI-Compatible Proxy

Send text, images, and audio through one proxy endpoint.

`oapix` forwards chat completions to your configured upstream, accepts image and audio inputs, converts audio URLs to mp3, and exposes media output as temporary URLs.

Endpoint

POST /v1/chat/completions

Use the proxy exactly like a chat completions API, then add multimodal content parts as needed.

Image Input

Provide `image_url.url` as an `https` URL, a data URL, or raw base64.

Audio Input

Provide `input_audio.data` plus `format`, or use `input_audio.url` and let the proxy convert it.
