# Recraft V4

> Generate a true scalable vector (SVG) graphic from a text prompt — ideal for logos, icons, and brand illustrations that stay crisp at any size.

## Overview

- **Endpoint**: `https://queue.modelrunner.run/recraft/v4/text-to-vector`
- **Model ID**: `recraft/v4/text-to-vector`
- **Category**: text-to-image
- **Kind**: inference
- **Tags**: recraft, recraft-v4, text-to-vector, vector, svg, logo, icon, design, illustration

## Pricing

- **Price**: $0.08 per output

## 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/v4/text-to-vector` with a JSON body. 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/v4/text-to-vector/requests/<request_id>/status",
  "response_url": "https://queue.modelrunner.run/recraft/v4/text-to-vector/requests/<request_id>",
  "cancel_url": "https://queue.modelrunner.run/recraft/v4/text-to-vector/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

- **`prompt`** (`string`, _required_):
  The text description of the vector graphic to generate (e.g. a logo, icon, or illustration). Output is a scalable SVG.

- **`image_size`** (`ImageSize | ImageSizeEnum`, _optional_):
  The size/aspect of the generated vector graphic. Pick a preset or supply an explicit width/height.
  - Default: `"square_hd"`
  - Options: `"square_hd"`, `"square"`, `"portrait_4_3"`, `"portrait_16_9"`, `"landscape_4_3"`, `"landscape_16_9"`

### Output Schema

_No `Output` schema properties are available._

## Default Example

**Input**

```json
{
  "prompt": "a friendly line-art owl mascot icon perched on a branch, single bold outline, flat two-tone vector illustration",
  "image_size": "square"
}
```

**Output**

```json
[
  "https://media.modelrunner.ai/8LM2YP3INOYpoupihZGCJ.svg"
]
```
## 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/v4/text-to-vector \
  --header "Authorization: Key $MODEL_RUNNER_KEY" \
  --header "Content-Type: application/json" \
  --data '{
  "prompt": "a friendly line-art owl mascot icon perched on a branch, single bold outline, flat two-tone vector illustration",
  "image_size": "square"
}')

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/v4/text-to-vector", {
  input: {
  "prompt": "a friendly line-art owl mascot icon perched on a branch, single bold outline, flat two-tone vector illustration",
  "image_size": "square"
}
});

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

### Python

```python
import asyncio
import modelrunner_ai

async def main():
    response = await modelrunner_ai.submit_async(
        "recraft/v4/text-to-vector",
        arguments={
  "prompt": "a friendly line-art owl mascot icon perched on a branch, single bold outline, flat two-tone vector illustration",
  "image_size": "square"
}
    )
    result = await response.get()
    print(result["output"])

asyncio.run(main())
```
