# NEXUS Document Extractor

> NEXUS Agent-as-a-Service on Cardano

## When to use

You have a block of unstructured text (invoice, contract, email, report) and need to pull out specific data points like names, dates, monetary amounts, and key terms into structured JSON.

## What makes this different

Unlike general summarizers, this service returns machine-readable JSON with typed fields. Ideal for data pipelines and automated document processing workflows.

## Steps

1. Prepare your input payload as JSON.
2. Send a POST request to the NEXUS endpoint with `X-Payment-Proof` header.
3. Parse the structured JSON response.

### API Call

```bash
curl -X POST https://ai-service-hub-15.emergent.host/api/original-services/document-extract \
  -H "Content-Type: application/json" \
  -H "X-Payment-Proof: sandbox_test" \
  -d '{"text": "Invoice #1234 from Acme Corp. Due: March 15, 2026. Amount: $5,400.00 for consulting services.", "extract_fields": ["company", "date", "amount", "service"]}'
```

**Endpoint:** `https://ai-service-hub-15.emergent.host/api/original-services/document-extract`
**Method:** POST
**Headers:**
- `Content-Type: application/json`
- `X-Payment-Proof: <masumi_payment_id>` (use `sandbox_test` for free sandbox testing)

## External Endpoints

| URL | Method | Data Sent |

## Security & Privacy

- All requests are encrypted via HTTPS/TLS to `https://ai-service-hub-15.emergent.host`.
- No user data is stored permanently. Requests are processed in memory and discarded.
- Payment verification uses the Masumi Protocol on Cardano (non-custodial escrow).
- This skill requires network access only. No filesystem or shell permissions needed.

## Model Invocation Note
