# Recraft V4.1 Utility Text to Image API

> Ngazi ya Pro ya mfululizo wa maandishi hadi picha wa V4.1 Utility, yenye vidokezo virefu na udhibiti wa rangi ya mandharinyuma

Huunda picha kutoka kwa kidokezo cha maandishi chenye hadi vibambo 10000. Unaweza kuelekeza mwonekano kwa palette ya `colors` na `background_color` inayopendelewa. `image_size` hutoa mipangilio sita, kutoka square_hd hadi portrait_16_9 na landscape_16_9. Kikagua usalama kimewashwa kwa chaguomsingi.

- Category: Text to Image
- Output: image
- Price: $0.21 / image (cheapest run $0.21 (210 API credits))
- Run: `POST https://api.doitong.ru/v1/run/recraft/v4.1/utility/pro/text-to-image`
- Quote: `POST https://api.doitong.ru/v1/quote/recraft/v4.1/utility/pro/text-to-image`
- Docs page: https://doitong.com/sw/developers/models/recraft/v4.1/utility/pro/text-to-image

## Pricing

Price: **$0.21 / image**. Billed per generated image.

The full example input below costs $0.21 = 210 API credits (1 image × 210 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.ru/v1/quote/recraft/v4.1/utility/pro/text-to-image` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  | 1 – 10000 characters |  |
| `image_size` |  | object {width, height} \| enum (string) | no | `square_hd` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` |  |
| `colors` |  | array of object {r, g, b} | no | `[]` |  | Mkusanyiko ulio na rangi zinazopendelewa. |
| `colors[].r` |  | integer | no | `0` | 0 – 255 | Thamani ya kipengele chekundu. |
| `colors[].g` |  | integer | no | `0` | 0 – 255 | Thamani ya kipengele cha kijani. |
| `colors[].b` |  | integer | no | `0` | 0 – 255 | Thamani ya kipengele cha samawati. |
| `background_color` |  | object {r, g, b} \| null | no |  |  | Rangi inayopendelewa ya mandharinyuma ya picha zinazozalishwa. |
| `background_color.r` |  | integer | no | `0` | 0 – 255 | Thamani ya kipengele chekundu. |
| `background_color.g` |  | integer | no | `0` | 0 – 255 | Thamani ya kipengele cha kijani. |
| `background_color.b` |  | integer | no | `0` | 0 – 255 | Thamani ya kipengele cha samawati. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Swichi ya ukaguzi wa usalama ambayo hali yake ya kuzimwa inahitaji uidhinishaji wa akaunti. Bila uidhinishaji huo, kila ombi hukaguliwa bila kujali mpangilio; true huwezesha kikagua. |

## Example input

Required parameters only:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.ru/v1/run/recraft/v4.1/utility/pro/text-to-image?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/recraft/v4.1/utility/pro/text-to-image?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.ru/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/recraft/v4.1/utility/pro/text-to-image", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.ru/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "recraft/v4.1/utility/pro/text-to-image",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
