# DWS Processor API

Nutrient DWS Processor API is an HTTP API that provides you with a simple document-in, document-out-based workflow that scales as you grow. Generate PDFs, convert documents to PDF, modify existing PDFs, and more.

## Quick start

Get started with Nutrient DWS Processor API using our SDK client libraries, or send raw HTTP requests.

### Installation

### Python

```sh

pip install nutrient-dws

```

### JavaScript

```sh

npm install @nutrient-sdk/dws-client-typescript

```

### curl

```sh

# No installation required.

# curl is available by default on most macOS/Linux environments.

```

### Example

### Python

```python

import asyncio
from nutrient_dws import NutrientClient

async def main():
    client = NutrientClient(api_key="YOUR_API_KEY")
    result = await client.convert("document.docx", "pdf")

    with open("output.pdf", "wb") as f:
        f.write(result.buffer)

asyncio.run(main())

```

### JavaScript

```js

import fs from "node:fs";
import { NutrientClient } from "@nutrient-sdk/dws-client-typescript";

async function main() {
  const client = new NutrientClient({ apiKey: "YOUR_API_KEY" });
  const result = await client.convert("document.docx", "pdf");

  fs.writeFileSync("output.pdf", Buffer.from(result.buffer));
}

main();

```

### curl

```bash

curl -L -o document.docx \
  https://www.nutrient.io/api/assets/downloads/samples/docx/document.docx

curl -X POST https://api.nutrient.io/build \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F 'document=@document.docx' \
  -F 'instructions={"parts":[{"file":"document"}]}' \
  --fail \
  -o output.pdf

```
