Give your automations reliable content steps
Automation builders do not need another isolated feature API. They need document intelligence, image transformation, generated deliverables, and spreadsheet outputs that fit cleanly into n8n, Make, Zapier, scripts, and internal workflow systems.

One output feeds the next
APIs that cover every step of your content pipeline — ingestion, transformation, and generation. One key, one credit pool, and structured JSON responses designed to chain together.
Mix and match freely
Extract data from a document, generate visuals from the results, then compile everything into a finished report. Mix, match, and build your own pipeline.
You're dealing with this every day
Here's what changes when you stop juggling tools and start building pipelines.
File movement is not file processing
Automation platforms can move uploads between apps, but invoice extraction, image cleanup, report generation, and spreadsheet output usually require separate services at every step.
Built for workflow tools
Use the n8n community node when you want visual building, or call the REST API directly from Make, Zapier, shell scripts, cron jobs, and internal automation services.
Pipelines break at service boundaries
One API returns a blob, another expects JSON, a third has its own retry behavior. Every handoff adds mapping logic, error paths, and brittle workflow branches.
Predictable JSON between steps
Extraction, transformation, and generation APIs return structured outputs that are meant to feed the next workflow step, not just a download link you need to parse manually.
Cost is hard to forecast
OCR, PDF generation, image processing, and spreadsheet tools each bill differently. That makes template pricing, client estimates, and internal automation budgets harder to explain.
Extract, transform, generate
Combine document extraction, document-to-markdown, website extraction, image transformation, document generation, image generation, and sheet generation from one account.
Real-world pipelines, ready to ship
Each recipe chains multiple APIs into a complete workflow. Pick one, tweak it, and deploy — or use it as a starting point for your own pipeline.
Extract Carrier Invoices to Spreadsheet
Extract line-level charges from multiple carrier invoices, then generate an XLSX freight cost tracker in a single pipeline.
Extract Contracts to a Register
Extract key terms from multiple signed contracts and build a structured XLSX contract register tracking parties, dates, value, and renewal terms.
Extract Customs Declarations to Spreadsheet
Extract HS codes, declared values, and duty amounts from customs declaration documents, then generate an XLSX import duty log.
Extract Invoices and Build Accounts Payable Spreadsheet
Extract structured data from multiple invoice PDFs in one call, then pipe the results directly into an XLSX accounts payable tracker.
Extract KPIs and Generate a Client Report
Extract key performance indicators from client documents, then generate a branded PDF report summarizing the results.
Extract Receipts and Generate Expense Report
Extract merchant, date, amount, and category from receipt photos and PDFs in one call, then generate an XLSX expense report with a totals row.
One n8n node for your entire pipeline
Most n8n document workflows chain three or four separate services. The Iteration Layer community node covers extraction, transformation, and generation in a single install — wire up multi-step pipelines visually instead of writing glue code.

Solving real problems, step by step
Vendor sprawl, GDPR headaches, broken pipelines — we wrote about the problems you're facing and how to fix them.
One n8n Node for Your Entire Document and Image Pipeline
Most n8n document workflows chain several separate services. The Iteration Layer community node replaces them with one integration for extraction, transformation, and generation.
Process Invoices in n8n Without Burning LLM Credits on Every Document
Most n8n invoice workflows chain OCR and LLM services that bill per token. Iteration Layer extracts structured invoice data at a fixed credit cost per document.
Convert Any Document to Clean Markdown in n8n
PDF, DOCX, HTML, images — convert them all to structured Markdown inside an n8n workflow. One node, no OCR chain, no LLM parsing.
Generate Formatted Excel Spreadsheets in n8n
Create multi-sheet XLSX files with formatting, formulas, and merged cells directly from n8n workflows — no code, no Google Sheets export.
Convert Markdown to Styled PDF in n8n
Turn Markdown content into professionally styled PDF documents inside n8n — with custom fonts, headers, footers, and page numbers.
Run a Complete Image Processing Pipeline with the Iteration Layer n8n Node
n8n's Edit Image node handles basics. For production pipelines — resize, crop, sharpen, watermark, convert — the Iteration Layer node runs multiple operations in one workflow.
