# Nutrient Openclaw

> OpenClaw-native PDF/document processing skill for Nutrient DWS. Best for OpenClaw users who need PDF conversion, OCR, text/table extraction, PII redaction, watermarking, digital signatures, and API credit checks via built-in `nutrient_*` tools. Triggers on OpenClaw tool names (`nutrient_convert_to_pdf`, `nutrient_extract_text`, etc.), "OpenClaw plugin", "Nutrient OpenClaw", and document-processing requests in OpenClaw chats. Files are processed by Nutrient DWS over the network, so use it only when third-party document processing is acceptable. For non-OpenClaw environments, use the Universal Nutrient Document Processing skill instead.

# Nutrient Document Processing (OpenClaw Native)

Best for OpenClaw users. Process documents directly in OpenClaw conversations — PDF conversion, text/table extraction, OCR, PII redaction, digital signatures, and watermarking via native `nutrient_*` tools.

## Installation

Preferred install flow inside OpenClaw:

```bash
openclaw plugins install @nutrient-sdk/nutrient-openclaw
```

Configure your API key:

```yaml
plugins:
  entries:
    nutrient-openclaw:
      config:
        apiKey: "your-api-key-here"
```

Get an API key at [nutrient.io/api](https://www.nutrient.io/api/)

## Data Handling

- `nutrient_*` operations send the file or extracted document content to Nutrient DWS for processing.
- Review Nutrient's [Processor API security](https://www.nutrient.io/api/documentation/security) and [privacy details](https://www.nutrient.io/api/processor-api/) before using production or sensitive documents.
- Nutrient documents its hosted Processor API as using HTTPS for data in transit and as not persistently storing input or output files after processing; confirm that matches your organization's requirements before uploading sensitive material.
- Start with non-sensitive sample files and a least-privilege API key.
