# PATINA · Material API

> Jenereta ya maandishi-hadi-texture inayotoa picha zinazoweza kurudiwa pamoja na ramani za PBR, ikiwa na img2img na inpainting za hiari

Huunda maumbo yanayoweza kurudiwa kutoka kwa kidokezo na kutabiri ramani za PBR: basecolor, normal, roughness, metalness na height. Tumia `tiling_mode` kwa upangaji wa kawaida, mlalo au wima, na `upscale_factor` ya 0, 2 au 4 kupanua ramani. Kutoa `image_url` huwasha image-to-image, na kuongeza `mask_url` huwasha inpainting. Hadi picha 4 kwa ombi.

- 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 |  |  | Maelezo ya maandishi ya nyenzo au texture ya kuunda. |
| `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` | Vipimo vya pikseli vya texture inayotokana. |
| `num_inference_steps` |  | integer | no | `8` | 1 – 8 | Idadi ya hatua za kuondoa noise zinazotumika kuzalisha textures. |
| `seed` |  | integer \| null | no |  |  | Seed nasibu inayofanya uzalishaji uweze kurudiwa. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Idadi ya picha za texture za kuunda. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Huwezesha upanuzi wa kidokezo unaotegemea LLM ili kuongeza maelezo. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Huwezesha ukaguzi wa usalama wa picha zinazozalishwa. |
| `tiling_mode` |  | enum (string) | no | `both` | `both`, `horizontal`, `vertical` | Mwelekeo wa tiling: 'both' kwa tiling ya pande zote, 'horizontal', au 'vertical'. |
| `tile_size` |  | integer | no | `128` | 32 – 256 | Ukubwa wa tile katika latent space, ambapo 64 inawakilisha 512px na 128 inawakilisha 1024px. Kwenye kila mhimili wa tile, kipimo cha picha inayozalishwa huweka kikomo cha juu kiotomatiki. |
| `tile_stride` |  | integer | no | `64` | 16 – 128 | Weka stride kati ya tiles za latent space; kikomo cha kiotomatiki huzuia kuzidi nusu ya ukubwa halisi wa tile. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | URL ya picha chanzo, inayotumika kwa inpainting ikiwa mask_url imeambatanishwa nayo na kwa uchakataji wa image-to-image vinginevyo. |
| `mask_url` | `mask` | string (image URL) \| null | no |  |  | URL ya maski ya inpainting iliyotolewa pamoja na image_url inayohitajika. Maski huhifadhi maeneo meusi bila mabadiliko na huzalisha upya maeneo meupe. |
| `strength` |  | number | no | `0.6` | ≤ 1, > 0 | Nguvu ya mabadiliko inayotumika tu kwenye picha iliyotolewa kupitia image_url; vinginevyo haitumiki. |
| `maps` |  | array of enum (string) | no | `["basecolor","normal","roughness","metalness","height"]` |  | Ramani za PBR zilizochaguliwa kwa utabiri, zote tano zikichaguliwa kwa chaguomsingi. Kutochagua yoyote huruka ukadiriaji wa PBR kabisa. |
| `upscale_factor` |  | enum (integer) | no | `0` | `0`, `2`, `4` | Kizidishi cha SeedVR cha kuongeza ukubwa bila mshono kinachoathiri ramani za PBR zilizotabiriwa lakini kinaacha texture ya msingi kwenye mwonekano wake wa asili. Chagua 2 kwa mwonekano wa mara mbili, 4 kwa mara nne, au 0 kuzima kuongeza ukubwa. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Muundo wa faili ya picha kwa textures na ramani za PBR za tokeo. |

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`.

```

## 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

### 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.
