# Nutrient Document Processing

> **Note:** This skill integrates with the Nutrient commercial API. Review their terms before use.

Process documents with the [Nutrient DWS Processor API](https://www.nutrient.io/api/). Convert formats, extract text and tables, OCR scanned documents, redact PII, add watermarks, digitally sign, and fill PDF forms.

## Quando usar

- "converte esse DOCX em PDF", "OCR nesse scan", "redige o CPF desse PDF"
- Extrair texto/tabela, watermark, assinatura digital, preencher form PDF
- Pipeline de documentos via API (NUTRIENT_API_KEY no env, nunca no chat)
- Não use para: edição colaborativa (isso é google-workspace-ops)

## Setup

Get a free API key at **[nutrient.io](https://dashboard.nutrient.io/sign_up/?product=processor)**

```bash
export NUTRIENT_API_KEY="pdf_live_..."
```

All requests go to `https://api.nutrient.io/build` as multipart POST with an `instructions` JSON field.
