# PATINA · Material API

> Text-till-textur-generator som ger tilebara bilder och PBR-kartor, med valfri img2img och inpainting

Skapar tilebara texturer från en prompt och förutsäger PBR-kartorna basecolor, normal, roughness, metalness och height. Använd `tiling_mode` för båda, horisontell eller vertikal plattsättning och `upscale_factor` på 0, 2 eller 4 för att förstora kartorna. Om `image_url` skickas aktiveras bild-till-bild och med `mask_url` aktiveras inpainting. Upp till 4 bilder per begäran.

- Model id: `patina/material`
- Made by: Open model
- Category: Text to Image
- Output: image
- Price per run: from $0.08 / run (cheapest run $0.08 (80 API credits))
- Run: `POST https://api.doitong.com/v1/run/patina/material`
- Quote: `POST https://api.doitong.com/v1/quote/patina/material`
- Docs page: https://doitong.com/sv/developers/models/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 |  |  | Textbeskrivning av materialet eller texturen som ska skapas. |
| `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` | Pixeldimensioner för den resulterande texturen. |
| `num_inference_steps` |  | integer | no | `8` | 1 – 8 | Antal avbrusningssteg som används för att generera texturer. |
| `seed` |  | integer \| null | no |  |  | Slumpmässigt seed som gör genereringen reproducerbar. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Antal texturbilder som ska skapas. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Aktiverar promptutvidgning baserad på LLM för att lägga till detaljer. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Aktiverar säkerhetskontroll av genererade bilder. |
| `tiling_mode` |  | enum (string) | no | `both` | `both`, `horizontal`, `vertical` | Kaklingsriktning: 'both' för rundriktad kakling, 'horizontal' eller 'vertical'. |
| `tile_size` |  | integer | no | `128` | 32 – 256 | Kakelstorlek i latentrymden, där 64 motsvarar 512px och 128 motsvarar 1024px. På varje kaklad axel sätter den genererade bildens dimension en automatisk övre gräns. |
| `tile_stride` |  | integer | no | `64` | 16 – 128 | Ange steget mellan kakel i latentrymden; ett automatiskt tak hindrar det från att överstiga hälften av den effektiva kakelstorleken. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | Källbildens URL, används för inpainting om mask_url medföljer och annars för bild-till-bild-bearbetning. |
| `mask_url` | `mask` | string (image URL) \| null | no |  |  | URL till inpainting-masken som tillhandahålls tillsammans med den obligatoriska image_url. Masken bevarar svarta områden oförändrade och genererar om vita områden. |
| `strength` |  | number | no | `0.6` | ≤ 1, > 0 | Transformationsstyrka som endast tillämpas på en bild som tillhandahålls via image_url; används annars inte. |
| `maps` |  | array of enum (string) | no | `["basecolor","normal","roughness","metalness","height"]` |  | PBR-kartor som valts för prediktion, där alla fem väljs som standard. Om inga väljs hoppas PBR-estimeringen över helt. |
| `upscale_factor` |  | enum (integer) | no | `0` | `0`, `2`, `4` | SeedVR:s sömlösa uppskalningsfaktor som påverkar predikterade PBR-kartor men låter bastexturen behålla sin ursprungliga upplösning. Välj 2 för dubbel upplösning, 4 för fyrdubbel upplösning eller 0 för att inaktivera uppskalning. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Bildfilformat för utdata-texturer och PBR-kartor. |

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:

}
```

```

## 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.
