# TRELLIS.2 Trainer API

> Moko Trellis 2 LoRA adapterius iš 3D išteklių zip failo, skirtus iki trims triukšmo mažintuvams

Patobulina adapterius iš `data_url` zip failo, kuriame yra neapdoroti 3D ištekliai arba iš anksto apdorotas duomenų rinkinys. `denoisers` pasirenka nuo 1 iki 3 tikslų, kurių kiekvienas mokomas kaip atskiras adapteris. Nustatymai: `resolution` 512 arba 1024, `rank` 16, 32 arba 64, `learning_rate` ir `training_steps` nuo 100 iki 10000. Grąžinami adapteriai, visos klaidos ir pakartotinai naudojami iš anksto apdoroti duomenys.

## Pricing

Price: **from $1.7508 / 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 $15.973 = 15973 API credits (1 run × $15.9723).

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/trellis-2-lora-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 |
|---|---|---|---|---|---|---|
| `data_url` |  | string | yes |  |  | Duomenų rinkinio archyvo URL: pateikite neapdorotus 3D išteklius, supakuotus kaip .zip, arba naudokite iš anksto apdoroto TRELLIS.2 duomenų rinkinio zip, grąžinamą naudojant data_preprocessing. |
| `denoisers` |  | array of enum (string) | no |  | 1 – 3 items | 1–3 skirtingų TRELLIS.2 triukšmo šalinimo modelių iš sparse_structure, geometry ir texture pasirinkimas patikslintam mokymui. Lygiagretusis mokymas naudoja bendrą iš anksto apdorotą duomenų rinkinį, kad sukurtų atskirą LoRA adapterį kiekvienam pasirinktam įrašui. |
| `resolution` |  | enum (integer) | no | `512` | `512`, `1024` | Mokymo raiška turi sutapti su duomenų rinkinio išankstinio apdorojimo raiška. Geometry ir texture mokymas turi atskiras 512 ir 1024 konfigūracijas, o sparse-structure mokymas šioms raiškoms naudoja bendrą konfigūraciją. |
| `rank` |  | enum (integer) | no | `32` | `16`, `32`, `64` | LoRA adapterio rangas; didesnės reikšmės suteikia adapteriui didesnę talpą. |
| `learning_rate` |  | number | no | `0.0001` | 0.000001 – 0.01 | Mokymosi sparta, naudojama LoRA optimizuoti. |
| `training_steps` |  | integer | no | `1000` | 100 – 10,000 | Bendras mokymo žingsnių skaičius. |

## Example input

Required parameters only:

```json
{
  "data_url": "https://example.com/your-file.zip"
}
```

A fuller example:

```json
{
  "data_url": "https://example.com/your-file.zip"
}
```

## 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/trellis-2-lora-trainer?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "data_url": "https://example.com/your-file.zip"
  }'

# 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/trellis-2-lora-trainer?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "data_url": "https://example.com/your-file.zip"
  }),
});
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 = {
    "data_url": "https://example.com/your-file.zip",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/trellis-2-lora-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": "trellis-2-lora-trainer",
      "input": {
        "data_url": "https://example.com/your-file.zip"
      },
      "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.

### Output fields (`output`)

| Field | Type | Description |
|---|---|---|
| `adapters` | array of object {denoiser, resolution, lora_file, rank, training_steps, learning_rate} | LoRA adapterių failai, susieti su atitinkamais trellis-2-lora išvadų laukais. Atsakyme pateikiamas po vieną adapterį kiekvienam sėkmingai išmokytam triukšmo šalinimo modeliui; jo failą naudokite atitinkamame lauke. |
| `failed` | array of object {denoiser, error} | Nesėkmingo triukšmo šalinimo modelio mokymo rezultatai; čia rodomi tik mokymo neužbaigę modeliai, todėl sėkmingai išmokus visus prašytus modelius šis laukas lieka tuščias. |
| `preprocessed_data_file` | object {url, content_type, file_name, file_size} | Mokymo metu naudotas iš anksto apdoroto TRELLIS.2 duomenų rinkinio zip, kurį galima naudoti pakartotinai. |
