# GPT Image 2.5 Text to Image API

> Myndlíkan OpenAI með góðri fylgni við leiðbeiningar, skýrri textateiknun og gegnsæjum bakgrunni.

Almennur myndframleiðandi OpenAI: fylgir löngum og nákvæmum leiðbeiningum, setur upp texta og skýringarmyndir skýrt og getur skilað PNG eða WebP með gegnsæjum bakgrunni fyrir límmiða, tákn og vörumyndir. Fimm gæðastig vega saman hraða, verð og smáatriði. Stærðir ná allt að 3840 px á lengri hlið (margfeldi af 16, í mesta lagi 3:1); allt að tíu myndir í hverri beiðni.

## Pricing

Price: **from $0.008 / image** (the lowest tier; the quote prices your exact input). Billed per generated image (`num_images`, default 1).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `image_size` is landscape_4_3, portrait_4_3: by `quality`, low: $0.008, medium: $0.013, high: $0.04, xhigh: $0.068, max: $0.148, auto: $0.148 / image
- When `image_size` is square_hd, square, portrait_16_9, landscape_16_9: by `quality`, low: $0.009, medium: $0.017, high: $0.056, xhigh: $0.097, max: $0.214, auto: $0.214 / image
- When `quality` is low, medium, high, xhigh, max, auto: by `quality`, low: $0.015, medium: $0.029, high: $0.104, xhigh: $0.181, max: $0.404, auto: $0.404 / image

The full example input below costs $0.017 = 17 API credits (1 image × 17 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/openai/gpt-image-2.5/flare/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

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  | 1 – 32000 characters | Kvaðning sem er notuð til að búa til myndir. |
| `image_size` |  | object {width, height} \| enum (string) | no | `landscape_4_3` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9`, `auto` | Mál úttaks taka við forstilltu heiti, {width, height}-hlut eða 'auto' fyrir besta stærðarval líkansins. Öll ákveðin mál verða að vera deilanleg með 16, brúnir mega ekki vera lengri en 3840px, stærðarhlutfall má mest vera 3:1 og heildarpixlafjöldi 655,360–8,294,400. |
| `background` |  | enum (string) | no | `auto` | `auto`, `transparent`, `opaque` | Bakgrunnur myndarinnar sem verður til. |
| `quality` |  | enum (string) | no | `high` | `auto`, `low`, `medium`, `high`, `xhigh`, `max` | Val á myndgæðum, þar sem 'auto' lætur líkanið taka ákvörðunina. Meiri smáatriði við hærri stillingar fylgja lengri biðtíma og meiri táknanotkun. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 10 | Fjöldi mynda sem á að búa til. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Skráarsnið úttaksmynda. |
| `output_compression` |  | integer \| null | no |  | 0 – 100 | Þjöppunarstilling sem er aðeins í boði fyrir 'jpeg' eða 'webp' í output_format; leyfilegt bil er 0–100. |

## Example input

Required parameters only:

```json
{
  "prompt": "A flat vector sticker of a smiling cactus wearing sunglasses, thick white outline, no background"
}
```

A fuller example:

```json
{
  "prompt": "A flat vector sticker of a smiling cactus wearing sunglasses, thick white outline, no background",
  "image_size": "square_hd",
  "quality": "medium",
  "background": "transparent"
}
```

## 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/openai/gpt-image-2.5/flare/text-to-image?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A flat vector sticker of a smiling cactus wearing sunglasses, thick white outline, no background",
    "image_size": "square_hd",
    "quality": "medium",
    "background": "transparent"
  }'

# 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/openai/gpt-image-2.5/flare/text-to-image?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A flat vector sticker of a smiling cactus wearing sunglasses, thick white outline, no background",
    "image_size": "square_hd",
    "quality": "medium",
    "background": "transparent"
  }),
});
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 flat vector sticker of a smiling cactus wearing sunglasses, thick white outline, no background",
    "image_size": "square_hd",
    "quality": "medium",
    "background": "transparent",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/openai/gpt-image-2.5/flare/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": "openai/gpt-image-2.5/flare/text-to-image",
      "input": {
        "prompt": "A flat vector sticker of a smiling cactus wearing sunglasses, thick white outline, no background",
        "image_size": "square_hd",
        "quality": "medium",
        "background": "transparent"
      },
      "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.
