## Request

POST https://api.revana.si/v1/generations with `Authorization: Bearer $REVANA_API_KEY` and an `Idempotency-Key` header: one key per request, made once and sent again on every resend after a timeout, a 429 or a 5xx, so the request is never made or charged twice. After a generation has failed, use a new key.

```json
{
  "model": "minimax-h3-image",
  "input": {
    "prompt": "A product photo of a ceramic coffee cup on a linen tablecloth, soft morning light",
    "resolution": "1K"
  },
  "max_cost_usd": 0.03
}
```

`max_cost_usd` is your cap, the most this request may cost (it lists at $0.02). Poll `GET /v1/generations/{id}` until `status` is `succeeded` or `failed`, then download `GET /v1/generations/{id}/content`. Full API: https://revana.si/llms.txt
