# PATINA · Material API

> Penjana teks-ke-tekstur yang menghasilkan imej boleh jubin bersama peta PBR, dengan img2img dan inpainting pilihan

Mencipta tekstur boleh jubin daripada prompt dan meramalkan peta PBR: basecolor, normal, roughness, metalness dan height. Gunakan `tiling_mode` untuk jubin kedua-dua arah, mendatar atau menegak, dan `upscale_factor` 0, 2 atau 4 untuk membesarkan peta. Menghantar `image_url` mengaktifkan imej-ke-imej, manakala menambah `mask_url` mengaktifkan inpainting. Sehingga 4 imej bagi setiap permintaan.

- Price per run: from $0.08 / run (cheapest run $0.08 (80 API credits))
- Run: `POST https://api.doitong.com/v1/run/patina/material`

## Pricing

Price: **from $0.08 / 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 $0.08 = 80 API credits (1 run × $0.08).

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/patina/material` 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 |  |  | Perihalan teks bahan atau tekstur untuk dicipta. |
| `image_size` |  | object {width, height} \| enum (string) | no | `square_hd` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | Dimensi piksel tekstur yang terhasil. |
| `num_inference_steps` |  | integer | no | `8` | 1 – 8 | Bilangan langkah penyahhingaran yang digunakan untuk menjana tekstur. |
| `seed` |  | integer \| null | no |  |  | Seed rawak yang menjadikan penjanaan boleh dihasilkan semula. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Bilangan imej tekstur untuk dicipta. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Mendayakan pengembangan prompt berasaskan LLM untuk menambah perincian. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Mendayakan pemeriksaan keselamatan imej yang dijana. |
| `tiling_mode` |  | enum (string) | no | `both` | `both`, `horizontal`, `vertical` | Arah jubinan: 'both' untuk jubinan semua arah, 'horizontal' atau 'vertical'. |
| `tile_size` |  | integer | no | `128` | 32 – 256 | Saiz jubin ruang laten, dengan 64 mewakili 512px dan 128 mewakili 1024px. Pada setiap paksi berjubin, dimensi imej yang dijana menetapkan had atas automatik. |
| `tile_stride` |  | integer | no | `64` | 16 – 128 | Tetapkan jarak antara jubin ruang laten; had automatik menghalangnya daripada melebihi separuh saiz jubin berkesan. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | URL imej sumber, digunakan untuk inpainting jika mask_url disertakan bersamanya dan untuk pemprosesan imej-ke-imej jika tidak. |
| `mask_url` | `mask` | string (image URL) \| null | no |  |  | URL topeng inpainting yang dibekalkan bersama image_url yang diperlukan. Topeng mengekalkan kawasan hitam tanpa perubahan dan menjana semula kawasan putih. |
| `strength` |  | number | no | `0.6` | ≤ 1, > 0 | Kekuatan transformasi yang hanya digunakan pada imej yang dibekalkan melalui image_url; jika tidak, tidak digunakan. |
| `maps` |  | array of enum (string) | no | `["basecolor","normal","roughness","metalness","height"]` |  | Peta PBR yang dipilih untuk ramalan, dengan kelima-limanya dipilih secara lalai. Jika tiada yang dipilih, anggaran PBR dilangkau sepenuhnya. |
| `upscale_factor` |  | enum (integer) | no | `0` | `0`, `2`, `4` | Faktor peningkatan skala lancar SeedVR yang mempengaruhi peta PBR yang diramalkan tetapi mengekalkan tekstur asas pada resolusi asalnya. Pilih 2 untuk resolusi dua kali ganda, 4 untuk resolusi empat kali ganda atau 0 untuk melumpuhkan peningkatan skala. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Format fail imej untuk tekstur output dan peta PBR. |

File parameters (`image`, `mask`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

}
```

A fuller example:

  "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/patina/material?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/patina/material?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/patina/material", 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": "patina/material",
      "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.
