🔍 Vision-Powered Detection

Redaction Detection API

Automatically detect and locate redacted content in PDFs using advanced vision AI. Identifies black boxes, white-out areas, blur effects, and other obscuration methods with precise bounding box coordinates. Perfect for compliance verification and document audit trails.

// Detect all redacted content in a document
const formData = new FormData();
formData.append('document_file', pdfFile);
formData.append('include_coordinates', 'true');

const response = await fetch('/api/strikethroughs', {
  method: 'POST',
  headers: { 'X-API-Key': 'your-api-key' },
  body: formData
});

const result = await response.json();

// Get all detected redactions with coordinates
console.log('Total redactions found:', result.redacted_items.length);

result.redacted_items.forEach(item => {
  console.log('Redaction found on page:', item.page);
  console.log('Bounding box:', item.bbox); // [x1, y1, x2, y2, x3, y3, x4, y4]
  console.log('Confidence:', item.confidence); // 0.0-1.0
  console.log('Reason:', item.reason); // Why it was detected as redacted
});

// Page metadata
console.log('Pages processed:', Object.keys(result.page_metadata).length);

Frequently Asked Questions

Everything you need to know

What types of redactions can the API detect?

The API uses advanced vision AI to detect solid black boxes, white-out areas, blur effects, color overlays, and other common obscuration methods. It returns precise bounding box coordinates and confidence scores for each detected redaction.

How accurate is the redaction detection?

Our vision AI achieves 95%+ accuracy in detecting redacted content. Each detection includes a confidence score (0.0-1.0) and a reason explaining why it was identified as redacted, allowing you to filter results based on your accuracy requirements.

What information is returned for each redaction?

Each redaction includes: precise bounding box coordinates (quadrilateral with 8 floats), page number (1-indexed), confidence score (0.0-1.0), and a brief explanation of why it was identified as redacted.

How does pricing work?

Redaction detection costs 2 credits per page, with coordinates always included. For example, scanning a 50-page document costs 100 credits ($1.00). Credits never expire.

Can I use this for compliance verification?

Yes! The API is designed for compliance use cases including FOIA processing, GDPR verification, HIPAA auditing, and legal document review. The coordinate data provides audit trails showing exactly where redactions were detected.

What's the maximum document size?

Documents can be up to 10MB in size and up to 50 pages per request. For larger documents, you can split them into multiple requests.
