# Qwen Image Edit 2509 Trainer API

> Hufunza LoRA maalum kwa Qwen Image Edit 2509 kutoka kwenye zip ya picha jozi za mwanzo na mwisho

Hutosheleza LoRA kwa mifano yako ya kabla/baada. `image_data_url` huelekeza kwenye zip ya jozi za picha zilizopewa majina ROOT_start.EXT na ROOT_end.EXT. Weka `steps` (1 hadi 30000, chaguomsingi 1000) na `learning_rate`, na kwa hiari `default_caption` kwa jozi zisizo na faili za maelezo. Hutoa faili ya usanidi na uzito wa LoRA wa diffusers.

## Pricing

Price: **from $0.40 / run** (the lowest tier; the quote prices your exact input). Price per run: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $4.00 = 4000 API credits (1 run × $4.00).

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/qwen-image-edit-2509-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 |
|---|---|---|---|---|---|---|
| `image_data_url` |  | string | yes |  |  | URL ya hifadhi ya ZIP iliyo na jozi za picha zenye majina ROOT_start.EXT na ROOT_end.EXT, kama photo_start.jpg na photo_end.jpg. Picha nyingi za marejeo kwa kila jozi zinaungwa mkono kwa kutumia ROOT_start.EXT, ROOT_start2.EXT, ROOT_start3.EXT, ..., ROOT_end.EXT (kwa mfano, photo_start.jpg, photo_start2.jpg, photo_end.jpg); weka Reference Image Count ilingane na jumla ya picha za marejeo. Kila jozi inaweza pia kuwa na maelekezo ya uhariri katika ROOT.txt (kwa mfano, photo.txt); bila faili hiyo, mafunzo hutumia default_caption, na mafunzo hushindwa ikiwa default_caption pia haipo. |
| `learning_rate` |  | number | no | `0.0001` |  | Kiwango kinachotumika kusasisha vigezo vya LoRA wakati wa kujifunza. |
| `steps` |  | integer | no | `1000` | 1 – 30,000 | Jumla ya idadi ya hatua za mafunzo. |
| `default_caption` |  | string \| null | no |  |  | Maelezo yanayotumiwa badala ya faili za maelezo zinazokosekana, huku None ikifanya kutokuwepo kwake kuwa kosa. |

## 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/qwen-image-edit-2509-trainer?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_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.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/qwen-image-edit-2509-trainer?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "image_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.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "image_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/qwen-image-edit-2509-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.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": "qwen-image-edit-2509-trainer",
      "input": {
        "image_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.
