# Create a realtime WebRTC call

`POST /v1/realtime/calls`

OpenAI-compatible WebRTC SDP exchange. Accepts a raw application/sdp offer with the model in the ?model= query parameter, or a multipart form with sdp and session (JSON) fields. The gateway routes by model, injects provider credentials, and relays the SDP answer; the Location header carries the created call id. Media flows directly between the client and the provider, so usage is recorded by a gateway-side sideband observer when usage tracking is enabled.

## Query parameters

- `model` string
- `provider` string

## Response `201`

SDP answer

- string

## Other responses

- `400` — Bad Request
- `401` — Unauthorized
- `429` — Too Many Requests
- `501` — Not Implemented
- `502` — Bad Gateway
