# Phota Text to Image API

> Text-to-image με επιλέξιμο βασικό μοντέλο και υποστήριξη εκπαιδευμένων προφίλ ταυτότητας στο prompt

Παράγει φωτογραφίες από prompt και μπορεί να αναφέρεται σε εκπαιδευμένα προφίλ μέσα στο κείμενο του prompt ως [[profile_id_1]] και ούτω καθεξής. Το `base_model` επιλέγει την απόδοση: nb2, qwen-image-2, flux-2 ή seedream-5-pro. Η `resolution` είναι 1K ή 4K, με 4K μόνο στο nb2. Οι αναλογίες διαστάσεων είναι auto, 1:1, 16:9, 4:3, 3:4 ή 9:16 και ανά κλήση επιστρέφονται 1 έως 4 εικόνες.

- Model id: `phota`
- Made by: Open model
- Category: Text to Image
- Output: image
- Price: from $0.09 / image (cheapest run $0.09 (90 API credits))
- Run: `POST https://api.doitong.com/v1/run/phota`
- Quote: `POST https://api.doitong.com/v1/quote/phota`
- Docs page: https://doitong.com/el/developers/models/phota

## Pricing

Price: **from $0.09 / 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 `resolution` = 4K: $0.18 (180 API credits) / image

The full example input below costs $0.09 = 90 API credits (1 image × 90 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.com/v1/quote/phota` 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 |  |  | Prompt παραγωγής εικόνας, στο οποίο μπορούν να αναφέρονται συγκεκριμένα προφίλ με [[profile_id_1]], [[profile_id_2]] και ούτω καθεξής· περιγράψτε την εικόνα που θέλετε να δημιουργήσετε. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Πλήθος εικόνων προς παραγωγή. |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | Μορφή αρχείου της τελικής εικόνας. |
| `resolution` |  | enum (string) | no | `1K` | `1K`, `4K` | Ανάλυση που θα χρησιμοποιηθεί για την παραγόμενη εικόνα. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `1:1`, `16:9`, `4:3`, `3:4`, `9:16` | Αναλογία πλάτους προς ύψος για την εικόνα εξόδου. |
| `base_model` |  | enum (string) | no | `nb2` | `nb2`, `qwen-image-2`, `flux-2`, `seedream-5-pro` | Επιλογή μοντέλου απόδοσης, με το `4K` διαθέσιμο μόνο μέσω του `nb2`. Τα επίπεδα ταυτότητας εφαρμόζονται πάνω από οποιοδήποτε επιλεγμένο βασικό μοντέλο, καθιστώντας κάθε επιλογή συμβατή με εκπαιδευμένα προφίλ. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Ο έλεγχος μπορεί να χαλαρώσει με τη ρύθμιση false, εφόσον ο καλών είναι εξουσιοδοτημένος. |

## 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.com/v1/run/phota?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.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/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/phota?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.com/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/phota", 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.com/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": "phota",
      "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.
