# Moondream API

> 프롬프트와 이미지 URL 쌍 목록을 받아 한 번의 호출로 여러 이미지에 대한 질문에 응답

Moondream vision-language 모델의 배치 버전입니다. `inputs`에 프롬프트와 이미지 URL을 담은 객체 목록을 전달하면 생성된 출력 목록과 처리된 파일명 및 타이밍을 반환합니다. 생성은 `max_tokens`(32~1024, 기본값 64), `temperature`(0~1), `top_p`, `repetition_penalty`(1~2)로 조정합니다. 응답에는 결과가 일부인지 여부를 나타내는 플래그도 포함됩니다.

- Model id: `moondream/batched`
- Made by: Moondream
- Category: Vision
- Output: json
- Estimated price per run: $0.004 / run (cheapest run $0.004 (4 API credits))
- Run: `POST https://api.doitong.com/v1/run/moondream/batched`
- Quote: `POST https://api.doitong.com/v1/quote/moondream/batched`
- Docs page: https://doitong.com/ko/developers/models/moondream/batched

## Pricing

Price: **$0.004 / run**. Estimated from the typical cost of one run. The quote is exactly what the run charges.

The full example input below costs $0.004 = 4 API credits (1 request × 4 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/moondream/batched` 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 |
|---|---|---|---|---|---|---|
| `inputs` |  | array of object {image_url, prompt} | yes |  |  | 이미지의 입력 프롬프트와 URL을 포함하는 목록입니다. |
| `inputs[].image_url` |  | string (image URL) | yes |  |  | 처리할 이미지를 가리키는 URL입니다. |
| `inputs[].prompt` |  | string | no | `Describe this image.` |  | 이미지에 적용된 프롬프트입니다. |
| `max_tokens` |  | integer | no | `64` | 32 – 1,024 | 새로 생성되는 토큰의 상한입니다. |
| `temperature` |  | number | no | `0.2` | ≤ 1, > 0 | 샘플링 온도 설정입니다. |
| `top_p` |  | number | no | `1` | 0 – 1 | 샘플링 top-P 설정입니다. |
| `repetition_penalty` |  | number | no | `1` | 1 – 2 | 샘플링 중 반복에 적용하는 패널티입니다. |

## Example input

Required parameters only:

```json
{
  "inputs": [
    {
      "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
    }
  ]
}
```

A fuller example:

```json
{
  "inputs": [
    {
      "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
    }
  ]
}
```

## 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/moondream/batched?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "inputs": [
      {
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      }
    ]
  }'

# 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/moondream/batched?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "inputs": [
      {
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      }
    ]
  }),
});
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 = {
    "inputs": [
        {
            "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        },
    ],
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/moondream/batched", 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": "moondream/batched",
      "input": {
        "inputs": [
          {
            "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
          }
        ]
      },
      "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.
