Build automated workflows with Iteration Layer and n8n — the open-source workflow automation platform.

Use dedicated Iteration Layer nodes to extract data from documents, transform images, generate graphics, and produce documents as part of larger automation pipelines. Self-host n8n or use n8n Cloud — both work with our APIs out of the box.

Available across all four APIs: Document Extraction, Image Transformation, Image Generation, and Document Generation.

Connect Iteration Layer to 5,000+ apps through Zapier — no code required.

Trigger workflows from document extractions, image transformations, generated images, and document outputs. Route results to Google Sheets, Slack, email, CRMs, and thousands of other services automatically.

Available across all four APIs: Document Extraction, Image Transformation, Image Generation, and Document Generation.

Iteration Layer is live — a unified API platform for content processing, built so developers never have to stitch together single-purpose services again.

We are launching with four production-ready APIs:

Document Extraction — AI-powered data extraction that turns PDFs, images, and office documents into structured JSON. Supports multi-file merge for combining data across documents in a single request, with field-level confidence scores you can actually trust.

Image Transformation — 24 operations covering resize, crop, format conversion, and more. Includes AI-powered upscaling, smart crop with object detection, and background removal — no ML infrastructure required on your end.

Image Generation — Deterministic, pixel-perfect image creation from JSON templates. A layer-based rendering engine with support for text, images, shapes, and QR codes, backed by 98 bundled fonts. Same input, same output, every time.

Document Generation — Generate PDF, DOCX, EPUB, and PPTX documents from JSON payloads. Bring your own fonts, use built-in templates, or define layouts from scratch. Ideal for invoices, reports, certificates, and contracts at scale.

All four APIs share a unified credit pool — one subscription, one balance, no per-service billing surprises. Every request is processed on EU-hosted infrastructure with full GDPR compliance and zero data retention by default.

For AI-native workflows, Iteration Layer ships with first-class MCP (Model Context Protocol) support, so tools like Claude and Cursor can call our APIs directly.
