• Comprehensive Timestamp Extraction: Extracts creation, modification, and publication timestamps from webpages
• Multiple Data Sources: Supports HTML meta tags, HTTP headers, JSON-LD, microdata, OpenGraph, Twitter cards, and heuristic analysis
• Confidence Scoring: Provides confidence levels (high/medium/low) for extracted timestamps
• Batch Processing: Extract timestamps from multiple URLs simultaneously
• Configurable: Customizable timeout, user agent, redirect handling, and heuristic options
• Production Ready: Robust error handling, comprehensive logging, and TypeScript support

API Reference

Tools

extract_timestamps

Extract timestamps from a single webpage.

Parameters:

• url (string, required): The URL of the webpage to extract timestamps from
• config (object, optional): Configuration options

Configuration Options:

• timeout (number): Request timeout in milliseconds (default: 10000)
• userAgent (string): User agent string for requests
• followRedirects (boolean): Whether to follow HTTP redirects (default: true)
• maxRedirects (number): Maximum number of redirects to follow (default: 5)
• enableHeuristics (boolean): Enable heuristic timestamp detection (default: true)

Example:

{
  "name": "extract_timestamps",
  "arguments": {
    "url": "https://example.com/article",
    "config": {
      "timeout": 15000,
      "enableHeuristics": true
    }
  }
}

batch_extract_timestamps

Extract timestamps from multiple webpages in batch.

Parameters:

• urls (array of strings, required): Array of URLs to extract timestamps from
• config (object, optional): Same configuration options as extract_timestamps

Example:

{
  "name": "batch_extract_timestamps",
  "arguments": {
    "urls": [
      "https://example.com/article1",
      "https://example.com/article2",
      "https://example.com/article3"
    ],
    "config": {
      "timeout": 10000
    }
  }
}

Response Format

Both tools return a JSON object with the following structure:

{
  url: string;
  createdAt?: Date;
  modifiedAt?: Date;
  publishedAt?: Date;
  sources: TimestampSource[];
  confidence: 'high' | 'medium' | 'low';
  errors?: string[];
}

TimestampSource:

{
  type: 'html-meta' | 'http-header' | 'json-ld' | 'microdata' | 'opengraph' | 'twitter' | 'heuristic';
  field: string;
  value: string;
  confidence: 'high' | 'medium' | 'low';
}

Examples

Basic Usage

import { TimestampExtractor } from './src/extractor.js';

const extractor = new TimestampExtractor();
const result = await extractor.extractTimestamps('https://example.com/article');

console.log('Published:', result.publishedAt);
console.log('Modified:', result.modifiedAt);
console.log('Confidence:', result.confidence);
console.log('Sources:', result.sources.length);

Custom Configuration

const extractor = new TimestampExtractor({
  timeout: 15000,
  userAgent: 'MyBot/1.0',
  enableHeuristics: false,
  maxRedirects: 3
});

const result = await extractor.extractTimestamps('https://example.com');

Batch Processing

const urls = [
  'https://example.com/article1',
  'https://example.com/article2',
  'https://example.com/article3'
];

const results = await Promise.all(
  urls.map(url => extractor.extractTimestamps(url))
);

Use Cases

• Content Freshness Analysis: Evaluate how recent web content is
• Web Scraping: Extract temporal metadata from scraped pages
• SEO Analysis: Analyze publication and modification patterns
• Research: Study temporal aspects of web content
• Content Management: Track content lifecycle and updates

Error Handling

The extractor handles various error conditions gracefully:

• Network Errors: Timeout, connection refused, DNS resolution failures
• HTTP Errors: 404, 500, and other HTTP status codes
• Parsing Errors: Invalid HTML, malformed JSON-LD, unparseable dates
• Configuration Errors: Invalid URLs, timeout values, etc.

All errors are captured in the errors array of the response, allowing for robust error handling and debugging.
