# Parserator Node.js SDK

> **Intelligent data parsing using the revolutionary Architect-Extractor pattern**

Transform any unstructured data into clean, structured JSON with AI-powered precision. The Parserator SDK implements a sophisticated two-stage LLM approach that maximizes accuracy while minimizing token costs.

## <† The Architect-Extractor Revolution

Parserator uses a groundbreaking **two-LLM approach** that outperforms traditional single-model parsing:

### <¨ **The Architect** (LLM 1)
- **Job**: Create a detailed parsing plan
- **Input**: Your desired schema + small data sample (~1000 chars)
- **Output**: Structured `SearchPlan` with precise extraction instructions
- **Benefit**: Complex reasoning on minimal data = ultra-low token cost

### ™ **The Extractor** (LLM 2)
- **Job**: Execute the parsing plan
- **Input**: Full data + the Architect's `SearchPlan`
- **Output**: Final structured JSON, validated against the plan
- **Benefit**: Direct execution with minimal "thinking" = maximum efficiency

**Result**: 70% reduction in token usage while achieving 95%+ accuracy rates.

## =€ Quick Start

### Installation

```bash
npm install @parserator/node-sdk
```

### Basic Usage

```javascript
const { ParseratorClient } = require('@parserator/node-sdk');

const client = new ParseratorClient({
  apiKey: 'pk_live_your_api_key_here'
});

const result = await client.parse({
  inputData: `
    John Smith
    Senior Developer
    john@techcorp.com
    (555) 123-4567
  `,
  outputSchema: {
    name: 'string',
    title: 'string', 
    email: 'email',
    phone: 'phone'
  }
});

console.log(result.parsedData);
// {
//   name: "John Smith",
//   title: "Senior Developer",
//   email: "john@techcorp.com",
//   phone: "(555) 123-4567"
// }
```

### Quick Parse Helper

```javascript
const { quickParse } = require('@parserator/node-sdk');

const result = await quickParse(
  'pk_live_your_api_key_here',
  'Raw unstructured data here...',
  { name: 'string', email: 'email' },
  'Extract contact information'
);
```

## =Ú API Reference

### ParseratorClient

```javascript
const client = new ParseratorClient({
  apiKey: 'pk_live_...', // Required: Your API key
  baseUrl: 'https://api.parserator.com', // Optional: Custom API URL
  timeout: 30000, // Optional: Request timeout (ms)
  retries: 3, // Optional: Max retry attempts
  debug: false // Optional: Enable debug logging
});
```

### parse(request)

```javascript
const result = await client.parse({
  inputData: 'string', // The unstructured data to parse
  outputSchema: {}, // Desired JSON structure
  instructions: 'string', // Optional: Additional context
  options: {
    timeout: 45000, // Request timeout override
    validateOutput: true, // Validate against schema
    confidenceThreshold: 0.8 // Minimum confidence (0-1)
  }
});
```

### batchParse(request, progressCallback?)

```javascript
const result = await client.batchParse({
  items: [/* array of parse requests */],
  options: {
    concurrency: 3, // Parallel processing limit
    failFast: false, // Stop on first error
    preserveOrder: true // Keep input order
  }
}, (progress) => {
  console.log(`${progress.completed}/${progress.total} completed`);
});
```

## =€ Examples

### Email Processing

```javascript
const { EMAIL_PARSER } = require('@parserator/node-sdk');

const result = await client.parse({
  inputData: `
    From: alice@company.com
    Subject: Q1 Review Meeting
    
    Hi team, let's schedule our Q1 review for Friday at 2 PM.
    Action items:
    - John: Prepare sales presentation
    - Sarah: Update financial forecasts
  `,
  outputSchema: EMAIL_PARSER.outputSchema,
  instructions: EMAIL_PARSER.instructions
});

console.log(result.parsedData.action_items);
// ["John: Prepare sales presentation", "Sarah: Update financial forecasts"]
```

### Invoice Processing

```javascript
const result = await client.parse({
  inputData: `
    INVOICE #INV-2024-001
    Date: January 15, 2024
    
    Bill To: Acme Corporation
    
    Web Development: 40 hrs @ $150/hr = $6,000
    Tax (8.5%): $510
    Total: $6,510
  `,
  outputSchema: {
    invoice_number: 'string',
    date: 'iso_date',
    client: 'string',
    line_items: 'object',
    subtotal: 'number',
    tax: 'number',
    total: 'number'
  }
});
```

### Batch Processing

```javascript
const documents = [
  { inputData: 'Contact 1...', outputSchema: contactSchema },
  { inputData: 'Invoice 1...', outputSchema: invoiceSchema },
  { inputData: 'Email 1...', outputSchema: emailSchema }
];

const batchResult = await client.batchParse({
  items: documents,
  options: { concurrency: 3 }
});

console.log(`Processed ${batchResult.summary.successful} items`);
```
