### Endpoint

POST https://openrouter.ai/api/v1/images

Headers:
- Content-Type: application/json

### Request fields (recraft/recraft-v4-pro-vector)

- model: string (required) — `"recraft/recraft-v4-pro-vector"`
- prompt: string (required) — text description of the desired image
- aspect_ratio: "1:1" | "4:3" | "3:4" | "16:9" | "9:16" | "auto" (optional) — aspect ratio of the generated image
- output_format: "svg" (optional) — encoding of the returned image bytes
- n: integer 1-6 (optional) — upper bound on the number of images to generate; providers may return fewer, and single-image providers reject n > 1
- input_references: array of up to 1 image references (optional) — reference images for image-to-image, as `{ "type": "image_url", "image_url": { "url": "…" } }` entries; the url is an https URL or a base64 data URL

These are the generation parameters this model accepts between its providers; an
unlisted value is rejected, and a listed one can still be refused by whichever provider
serves the call. `provider` (routing preferences) is accepted on every request.

### Response

```json
{
  "created": 1748372400,
  "data": [{ "b64_json": "<base64 image bytes>", "media_type": "image/png" }],
  "usage": { "prompt_tokens": 0, "completion_tokens": 4175, "total_tokens": 4175, "cost": 0.04 }
}
```

Base64-decode `data[i].b64_json` and write the bytes to a file; `media_type` gives the extension.
`usage.cost` is the USD charge for the call.

Potted plants and a bicycle rest by the entrance, and golden light spills across the wet pavement in gentle reflections. Straight-on composition, quiet street with no people.",
