Pass-through endpoint compatible with upstream Responses API.
On this page
What it does
Uni API exposes /v1/responses and forwards the request body and headers upstream, while still enforcing your API key authentication and recording usage.
Usage accounting
- When upstream returns
cached_tokens, cached tokens are billed at 10% of the input price. - Logs display Input / Cached / Output tokens when present.
