# PATINA · Material API

> Generator tekstur iz besedila, ki ustvari ponovljive slike in zemljevide PBR z izbirnima img2img in inpainting

Ustvari ponovljive teksture iz poziva in napove zemljevide PBR: basecolor, normal, roughness, metalness in height. Z `tiling_mode` izberite obojestransko, vodoravno ali navpično ponavljanje, z `upscale_factor` 0, 2 ali 4 pa povečajte zemljevide. Posredovanje `image_url` omogoči pretvorbo slike v sliko, dodajanje `mask_url` pa inpainting. Do 4 slike na zahtevo.

- 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`

## 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 |  |  | Besedilni opis materiala ali teksture za ustvarjanje. |
| `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` | Mere slikovnih pik končne teksture. |
| `num_inference_steps` |  | integer | no | `8` | 1 – 8 | Število korakov odstranjevanja šuma za ustvarjanje tekstur. |
| `seed` |  | integer \| null | no |  |  | Naključni seed, ki omogoča ponovljivo generiranje. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Število slik tekstur za ustvarjanje. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Omogoča razširjanje poziva na podlagi LLM za dodajanje podrobnosti. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Omogoča preverjanje varnosti ustvarjenih slik. |
| `tiling_mode` |  | enum (string) | no | `both` | `both`, `horizontal`, `vertical` | Smer tlakovanja: 'both' za vsesmerno tlakovanje, 'horizontal' ali 'vertical'. |
| `tile_size` |  | integer | no | `128` | 32 – 256 | Velikost ploščice v latentnem prostoru, pri čemer 64 predstavlja 512px, 128 pa 1024px. Na vsaki tlakovanji osi mera ustvarjene slike določa samodejno zgornjo mejo. |
| `tile_stride` |  | integer | no | `64` | 16 – 128 | Nastavite korak med ploščicami v latentnem prostoru; samodejna omejitev prepreči, da bi presegel polovico učinkovite velikosti ploščice. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | URL izvorne slike, uporabljen za izpolnjevanje, če ga spremlja mask_url, sicer za obdelavo image-to-image. |
| `mask_url` | `mask` | string (image URL) \| null | no |  |  | URL maske za izpolnjevanje, posredovan skupaj z zahtevanim image_url. Maska ohrani črna območja nespremenjena in ponovno ustvari bela območja. |
| `strength` |  | number | no | `0.6` | ≤ 1, > 0 | Jakost pretvorbe, uporabljena samo za sliko, posredovano prek image_url; sicer se ne uporablja. |
| `maps` |  | array of enum (string) | no | `["basecolor","normal","roughness","metalness","height"]` |  | PBR-zemljevidi, izbrani za napoved, pri čemer je vseh pet privzeto izbranih. Če ne izberete nobenega, se ocenjevanje PBR v celoti preskoči. |
| `upscale_factor` |  | enum (integer) | no | `0` | `0`, `2`, `4` | Faktor povečevanja SeedVR brez šivov, ki vpliva na napovedane PBR-zemljevide, osnovno teksturo pa pusti v izvirni ločljivosti. Izberite 2 za dvojno ločljivost, 4 za štirikratno ločljivost ali 0 za onemogočanje povečave. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Oblika datoteke slike za izhodne teksture in PBR-zemljevide. |

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:

```json
{
  "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.
