# Meshy 7 Retexture API

> 3D রিটেক্সচারিংয়ের Meshy 7 সংস্করণ: প্রম্পট বা স্টাইল ছবি থেকে নতুন চেহারা, ঐচ্ছিক PBR আউটপুটসহ

একটি সরবরাহ করা 3D ফাইলে (.glb, .gltf, .obj, .fbx, .stl) সর্বোচ্চ 600 অক্ষরের টেক্সট বর্ণনা অথবা একটি 2D স্টাইল ছবি ব্যবহার করে নতুন টেক্সচার প্রয়োগ করে; উভয়টি পাঠালে ছবিটি অগ্রাধিকার পায়। বেস কালার রেজোলিউশন 2k, 4k বা 8k হতে পারে, এবং 8k-তে PBR ম্যাপ 4k-তে নেমে যায় ও emission ম্যাপ থাকে না। বিদ্যমান UV বজায় রাখতে `enable_original_uv` সেট করুন এবং metallic, roughness ও normal ম্যাপ পেতে `enable_pbr` ব্যবহার করুন। GLB-এর পাশাপাশি অন্যান্য ফরম্যাট ও টেক্সচার ফাইল ফেরত দেয়।

- Model id: `meshy/v7/retexture`
- Made by: Meshy
- Category: 3D
- Output: 3d
- Price: from $0.30 / request (cheapest run $0.30 (300 API credits))
- Run: `POST https://api.doitong.com/v1/run/meshy/v7/retexture`
- Quote: `POST https://api.doitong.com/v1/quote/meshy/v7/retexture`
- Docs page: https://doitong.com/bn/developers/models/meshy/v7/retexture

## Pricing

Price: **from $0.30 / request** (the lowest tier; the quote prices your exact input). Billed once per request.

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `texture_resolution` = 8k: $0.45 (450 API credits) / request

The full example input below costs $0.30 = 300 API credits (1 request × 300 API credits).

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/meshy/v7/retexture` 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 |
|---|---|---|---|---|---|---|
| `model_url` |  | string | yes |  |  | টেক্সচারিংয়ের জন্য 3D মডেলের উৎস, যা হয় সর্বসাধারণের জন্য অ্যাক্সেসযোগ্য URL, নয়তো application/octet-stream-কে MIME type হিসেবে ব্যবহার করা একটি base64 data URI। গ্রহণযোগ্য ফাইল এক্সটেনশন হলো .glb, .gltf, .obj, .fbx এবং .stl। |
| `text_style_prompt` |  | string \| null | no |  | ≤ 600 characters | টেক্সচার-স্টাইলের টেক্সট, image_style_url না থাকলে আবশ্যক এবং 600 অক্ষরের মধ্যে সীমাবদ্ধ। |
| `image_style_url` |  | string (image URL) \| null | no |  |  | image_style_url হিসেবে সরবরাহ করা হলে text_style_prompt-এর চেয়ে অগ্রাধিকার পাওয়া 2D টেক্সচারিং গাইড। text_style_prompt না থাকলে এই ছবি সরবরাহ করুন; সমর্থিত ফাইলের ধরন হলো .jpg, .jpeg এবং .png। |
| `texture_resolution` |  | enum (string) | no | `2k` | `2k`, `4k`, `8k` | বেস-কালার রেজোলিউশনের বিকল্প হলো 2k (2048), 4k (4096) এবং 8k (8192)। 8k নির্বাচন করলে PBR ম্যাপ 4k-তে সীমাবদ্ধ থাকে এবং emission ম্যাপ বাদ যায়; 8k ও 4k উভয়ই কেবল Meshy 6 বা 7-এ উপলভ্য। |
| `enable_original_uv` |  | boolean | no | `true` |  | এই বিকল্প সক্রিয় করে UV পুনরায় তৈরি না করে সেগুলো অক্ষুণ্ণ রাখুন। মূল UV mapping না থাকা মডেলের ক্ষেত্রে এটি সক্রিয় করলে মান কমে যেতে পারে। |
| `enable_pbr` |  | boolean | no | `false` |  | বেস কালারের পাশাপাশি metallic, roughness এবং normal PBR ম্যাপের জেনারেশন নিয়ন্ত্রণ করে। |
| `enable_safety_checker` |  | boolean | no | `true` |  | প্রিপ্রসেসিং সেফটি-চেক সুইচ: true করলে প্রসেসিংয়ের পূর্বশর্ত হিসেবে একটি ইনপুট সেফটি চেক করা হয়। |

File parameters (`image_style_url`) 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:

```json
{
  "model_url": "https://example.com/your-file.glb"
}
```

A fuller example:

```json
{
  "model_url": "https://example.com/your-file.glb"
}
```

## 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/meshy/v7/retexture?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model_url": "https://example.com/your-file.glb"
  }'

# 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/meshy/v7/retexture?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "model_url": "https://example.com/your-file.glb"
  }),
});
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 = {
    "model_url": "https://example.com/your-file.glb",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/meshy/v7/retexture", 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": "meshy/v7/retexture",
      "input": {
        "model_url": "https://example.com/your-file.glb"
      },
      "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.
