# Ideogram V4.0q LoRA Trainer API

> Εκπαιδεύει προσαρμοσμένο LoRA για Ideogram V4 από zip εικόνων με λεζάντες

Εκπαιδεύει ένα LoRA στο δικό σας σύνολο δεδομένων για εξατομίκευση ή συγκεκριμένο στυλ. Το `images_data_url` δείχνει σε zip εικόνων, με λεζάντες από αρχεία .txt με το ίδιο όνομα, ενώ το `default_caption` συμπληρώνει όσες λείπουν. Το `steps` κυμαίνεται από 100 έως 40000 (προεπιλογή 1000) και τα `learning_rate` και `resolution` είναι ρυθμιζόμενα. Επιστρέφει το αρχείο βαρών LoRA και ένα αρχείο ρυθμίσεων.

## Pricing

Price: **$0.00675 / step**. Billed per training step (`steps`).

The full example input below costs $6.75 = 6750 API credits (1000 steps × 6.75 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/ideogram/v4/trainer` 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 |
|---|---|---|---|---|---|---|
| `images_data_url` |  | string | yes |  |  | URL ZIP δεδομένων εκπαίδευσης που περιέχει εικόνες και λεζάντες, με κάθε λεζάντα αποθηκευμένη σε αρχείο .txt που έχει το ίδιο βασικό όνομα με το αρχείο εικόνας. Ο εκπαιδευτής χρησιμοποιεί το σύνολο δεδομένων μόνο του στόχου που προετοιμάζει το prepare_dataset_dir. |
| `steps` |  | integer | no | `1000` | 100 – 40,000 | Αριθμός βημάτων για εκπαίδευση LoRA. |
| `default_caption` |  | string \| null | no |  |  | Λεζάντα που εφαρμόζεται σε κάθε εικόνα όταν το force_default_caption είναι true, παρακάμπτοντας τα αρχεία λεζαντών· διαφορετικά, χρησιμοποιείται μόνο για εικόνες χωρίς αρχείο λεζάντας. |
| `resolution` |  | string | no | `auto` |  | Διαστάσεις εικόνων εκπαίδευσης, καθορισμένες ως προεπιλογή, auto ή προσαρμοσμένη συμβολοσειρά WIDTHxHEIGHT με κάθε διάσταση διαιρετή με 16. Η κεντρική περικοπή δεν αυξάνει ποτέ την ανάλυση των εικόνων· το auto επιλέγει τη μεγαλύτερη κοινή περικοπή του συνόλου δεδομένων που δεν απαιτεί μεγέθυνση. Οι προεπιλογές είναι 1024x1024 (τετράγωνο), 1536x1024 (οριζόντιο), 1024x1536 (κατακόρυφο), 1920x1088 (ευρεία οθόνη), 2048x768 (υπερευρεία), 1024x1792 (phone_wallpaper) και 1584x400 (social_banner). |
| `learning_rate` |  | number | no | `0.0001` | 0.000001 – 0.01 |  |

## Example input

Required parameters only:

```json
{
  "images_data_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "images_data_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

## 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/ideogram/v4/trainer?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "images_data_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }'

# 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/ideogram/v4/trainer?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "images_data_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }),
});
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 = {
    "images_data_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/ideogram/v4/trainer", 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": "ideogram/v4/trainer",
      "input": {
        "images_data_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "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.
