## Request Lifecycle

This model runs on the ModelRunner **asynchronous queue API** — a single POST does not return the output. Every call requires an `Authorization: Key $MODEL_RUNNER_KEY` header. Run three steps:

1. **Submit** — `POST https://queue.modelrunner.run/recraft/v3/image-to-image` with a JSON body holding the input fields at the top level. The body may also include a reserved top-level `metadata` object — a flat string map (max 16 keys, key ≤64 / value ≤512 chars) stored on the request for your own tagging. It is never sent to the model; filter your request history with `GET https://queue.modelrunner.run/requests?metadata=<url-encoded JSON>` (exact key=value matches, AND-ed). The response carries request handles only (no output yet):

```json
{
  "status": "IN_QUEUE",
  "request_id": "<21-char id>",
  "status_url": "https://queue.modelrunner.run/recraft/v3/image-to-image/requests/<request_id>/status",
  "response_url": "https://queue.modelrunner.run/recraft/v3/image-to-image/requests/<request_id>",
  "cancel_url": "https://queue.modelrunner.run/recraft/v3/image-to-image/requests/<request_id>/cancel"
}
```

2. **Poll status** — `GET <status_url>` until `status` is `COMPLETED`. Possible values are `IN_QUEUE`, `IN_PROGRESS`, `COMPLETED`, `FAILED`, `CANCELLED`. A `FAILED` request responds with HTTP 400 and an `error` field.

3. **Read result** — `GET <response_url>`. Returns the finished request, including the generated `output`:

```json
{ "id": "<request_id>", "status": "COMPLETED", "output": ..., "input": ... }
```

The JavaScript and Python SDKs below perform steps 2–3 for you. In any language without an SDK (Swift, Go, Kotlin, etc.) you must implement the polling loop and the final result fetch yourself — see the cURL example for the full flow.

### Input Schema

- **`style`** (`StyleEnum`, _optional_):
  The visual style to render. Pick a top-level family or a specific substyle. Any 'vector_illustration/*' style returns a true vector (SVG) file; all other styles return a raster image. Vector styles cost 2X as much.
  - Default: `"realistic_image"`
  - Options: `"any"`, `"realistic_image"`, `"digital_illustration"`, `"vector_illustration"`, `"realistic_image/b_and_w"`, `"realistic_image/enterprise"`, `"realistic_image/evening_light"`, `"realistic_image/faded_nostalgia"`, `"realistic_image/forest_life"`, `"realistic_image/hard_flash"`, `"realistic_image/hdr"`, `"realistic_image/motion_blur"`, `"realistic_image/mystic_naturalism"`, `"realistic_image/natural_light"`, `"realistic_image/natural_tones"`, `"realistic_image/organic_calm"`, `"realistic_image/real_life_glow"`, `"realistic_image/retro_realism"`, `"realistic_image/retro_snapshot"`, `"realistic_image/studio_portrait"`, `"realistic_image/urban_drama"`, `"realistic_image/village_realism"`, `"realistic_image/warm_folk"`, `"digital_illustration/2d_art_poster"`, `"digital_illustration/2d_art_poster_2"`, `"digital_illustration/antiquarian"`, `"digital_illustration/bold_fantasy"`, `"digital_illustration/child_book"`, `"digital_illustration/child_books"`, `"digital_illustration/cover"`, `"digital_illustration/crosshatch"`, `"digital_illustration/digital_engraving"`, `"digital_illustration/engraving_color"`, `"digital_illustration/expressionism"`, `"digital_illustration/freehand_details"`, `"digital_illustration/grain"`, `"digital_illustration/grain_20"`, `"digital_illustration/graphic_intensity"`, `"digital_illustration/hand_drawn"`, `"digital_illustration/hand_drawn_outline"`, `"digital_illustration/handmade_3d"`, `"digital_illustration/hard_comics"`, `"digital_illustration/infantile_sketch"`, `"digital_illustration/long_shadow"`, `"digital_illustration/modern_folk"`, `"digital_illustration/multicolor"`, `"digital_illustration/neon_calm"`, `"digital_illustration/noir"`, `"digital_illustration/nostalgic_pastel"`, `"digital_illustration/outline_details"`, `"digital_illustration/pastel_gradient"`, `"digital_illustration/pastel_sketch"`, `"digital_illustration/pop_art"`, `"digital_illustration/pop_renaissance"`, `"digital_illustration/seamless"`, `"digital_illustration/street_art"`, `"digital_illustration/tablet_sketch"`, `"digital_illustration/urban_glow"`, `"digital_illustration/urban_sketching"`, `"digital_illustration/vanilla_dreams"`, `"digital_illustration/young_adult_book"`, `"digital_illustration/young_adult_book_2"`, `"vector_illustration/bold_stroke"`, `"vector_illustration/chemistry"`, `"vector_illustration/colored_stencil"`, `"vector_illustration/contour_pop_art"`, `"vector_illustration/cosmics"`, `"vector_illustration/cutout"`, `"vector_illustration/depressive"`, `"vector_illustration/editorial"`, `"vector_illustration/emotional_flat"`, `"vector_illustration/engraving"`, `"vector_illustration/infographical"`, `"vector_illustration/line_art"`, `"vector_illustration/line_circuit"`, `"vector_illustration/linocut"`, `"vector_illustration/marker_outline"`, `"vector_illustration/mosaic"`, `"vector_illustration/naivector"`, `"vector_illustration/roundish_flat"`, `"vector_illustration/segmented_colors"`, `"vector_illustration/sharp_contrast"`, `"vector_illustration/thin"`, `"vector_illustration/vivid_shapes"`

- **`prompt`** (`string`, _required_):
  The text prompt describing how to restyle or change the image.

- **`strength`** (`number`, _optional_):
  How far the result departs from the original image (denoising strength). 0 stays close to the input, 1 transforms heavily.
  - Default: `0.5`
  - Range: `0` to `1`

- **`image_url`** (`string`, _required_):
  URL of the source image to restyle (max 5MB, 16MP, 4096px per side).

- **`negative_prompt`** (`string | null`, _optional_):
  Text describing elements to avoid in the result.

## Usage Examples

### cURL

The queue API is asynchronous: submit the request, poll `status_url` until it is `COMPLETED`, then read the result from `response_url`. Requires `jq`.

```bash
# 1. Submit the request (returns request handles, not the output)
SUBMIT=$(curl --silent --request POST \
  --url https://queue.modelrunner.run/recraft/v3/image-to-image \
  --header "Authorization: Key $MODEL_RUNNER_KEY" \
  --header "Content-Type: application/json" \
  --data '{
  "style": "digital_illustration/hand_drawn",
  "prompt": "Restyle this cafe still life as a cozy hand-drawn storybook illustration with warm tones and soft outlines",
  "strength": 0.55,
  "image_url": "https://media.modelrunner.ai/qpVDYUNXosDmWAFh-recraft-i2i-probe-source-coffee-cup.png"
}')

STATUS_URL=$(echo "$SUBMIT" | jq -r '.status_url')
RESPONSE_URL=$(echo "$SUBMIT" | jq -r '.response_url')

# 2. Poll until the request leaves the queue / in-progress state
while true; do
  STATUS=$(curl --silent --url "$STATUS_URL" \
    --header "Authorization: Key $MODEL_RUNNER_KEY" | jq -r '.status')
  echo "Status: $STATUS"
  case "$STATUS" in
    COMPLETED) break ;;
    FAILED|CANCELLED) echo "Request $STATUS"; exit 1 ;;
  esac
  sleep 1
done

# 3. Read the finished request, including the generated output
curl --silent --url "$RESPONSE_URL" \
  --header "Authorization: Key $MODEL_RUNNER_KEY"
```

### JavaScript

```javascript
import { modelrunner } from "@modelrunner/client";

const result = await modelrunner.subscribe("recraft/v3/image-to-image", {
  input: {
  "style": "digital_illustration/hand_drawn",
  "prompt": "Restyle this cafe still life as a cozy hand-drawn storybook illustration with warm tones and soft outlines",
  "strength": 0.55,
  "image_url": "https://media.modelrunner.ai/qpVDYUNXosDmWAFh-recraft-i2i-probe-source-coffee-cup.png"
}
});

console.log(result.data);
```

### Python

```python
import asyncio
import modelrunner_ai

async def main():
    response = await modelrunner_ai.submit_async(
        "recraft/v3/image-to-image",
        arguments={
  "style": "digital_illustration/hand_drawn",
  "prompt": "Restyle this cafe still life as a cozy hand-drawn storybook illustration with warm tones and soft outlines",
  "strength": 0.55,
  "image_url": "https://media.modelrunner.ai/qpVDYUNXosDmWAFh-recraft-i2i-probe-source-coffee-cup.png"
}
    )
    result = await response.get()
    print(result["output"])

asyncio.run(main())
```
