Resources

The node provides one resource per Iteration Layer API:

Document Extraction

Extract structured data from PDFs, images, DOCX, and more. Define a schema with field names, types, and descriptions — the API returns typed values with confidence scores.

• File input: Binary data from a previous node or a public URL
• Schema: Build via the UI (17 field types) or provide raw JSON for advanced schemas (arrays, calculated fields)

Website Extraction

Extract structured data from public website pages with the same schema builder used by Document Extraction.

• Website URL: Public HTTPS URL, with optional custom user agent, locale, timeout, and JavaScript rendering
• Schema: Build via the UI or provide raw JSON for advanced schemas

Image Transformation

Apply image operations sequentially: resize, crop, rotate, blur, sharpen, convert format, upscale, remove background, and more (24 operations total).

• File input: Binary data or URL
• Operations: Add multiple operations via the UI — each type shows its specific parameters

Image Generation

Generate images from layer compositions defined as JSON. Supports solid-color, text, image, QR code, barcode, and gradient layers.

• Dimensions: Width and height in pixels
• Layers: JSON array defining the composition (see API docs)
• Output format: PNG, JPEG, WebP, TIFF, GIF, or AVIF

Document Generation

Generate PDF, DOCX, EPUB, or PPTX documents from structured JSON definitions including metadata, page layout, styles, and content blocks.

• Format: PDF, DOCX, EPUB, or PPTX
• Document: JSON object with the full document definition (see API docs)

Document to Markdown

Convert PDFs, DOCX, PPTX, and other documents into clean, structured Markdown.

• File input: Binary data or URL
• Output: Markdown text with the document's content

Sheet Generation

Generate XLSX, CSV, or Markdown spreadsheets from structured JSON definitions.

• Sheets: JSON array defining sheet names, columns, and row data
• Styles: Optional header and body cell styles
• Output format: XLSX, CSV, or Markdown

Binary Data

Image Transformation, Image Generation, Document Generation, and Sheet Generation return binary data. The output is available as n8n binary data that you can pass to downstream nodes (e.g., write to disk, send via email, upload to S3).

Document Extraction returns JSON data with extracted field values and confidence scores. Document to Markdown returns JSON with the markdown text.

Async Mode

All resources support async mode. Enable it and provide a webhook URL — the API returns immediately and delivers results to your webhook when processing is complete.
