Client n8n workflows break when files need processing
Clients want n8n to read supplier invoices, CMR waybills, delivery notes, and property documents, then clean images, generate PDFs, and export spreadsheet rows. Those file steps often become HTTP nodes and vendor mappings. Iteration Layer handles them through one verified node with project keys and usage tracking.
One output feeds the next
APIs that cover every step of EU content workflows — ingestion, transformation, generation, and exports. One key, one credit pool, and structured JSON responses designed to chain together.
Extract inputs
Turn documents, websites, and other sources into structured output.
Generate outputs
Create images, spreadsheets, and files from the same workflow state.
Image Transformation
Resize, crop, upscale, and convert images in one request.
Image Generation
Compose dynamic images from layers, text, QR codes, and fonts.
Document Generation
Generate PDF, DOCX, EPUB, and PPTX files from JSON content.
Sheet Generation
Generate XLSX and CSV sheets with formulas and styles.
EU AI workflow runtime
Run document, image, and file steps through one EU-hosted workflow layer with shared API conventions and billing.
Where client n8n workflows get expensive
n8n can orchestrate the flow. The friction starts when EU invoices, logistics documents, product images, PDFs, and spreadsheets need reliable processing inside the same client automation.
HTTP nodes take over file work
Moving files between apps is easy. Extracting fields, cleaning images, generating PDFs, and exporting sheets often means custom HTTP nodes and mappings for every provider.
Verified node for real file products
Use Document Extraction, Image Transformation, Document Generation, and Sheet Generation through the verified Iteration Layer n8n node instead of separate HTTP integrations.
Client usage becomes hard to price
When invoice extraction, CMR processing, image work, generated reports, and spreadsheets each bill differently, the monthly client report turns into reconciliation instead of a clean per-project view.
Project keys per client
Create one project per client, issue scoped API keys, set optional budget caps, and keep usage visible without splitting the agency account.
Automations still need deliverables
A useful n8n workflow rarely ends with raw JSON. Clients expect approval PDFs, cleaned images, spreadsheet exports, and files they can hand to another team.
Generated outputs stay in n8n
Extract VAT IDs and IBANs, generate approval PDFs, resize marketplace listing images, and export XLSX files without leaving the same n8n workflow and credit pool.
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.
Convert Contract to Markdown
Convert a contract PDF to clean markdown for clause extraction or LLM analysis.
Convert Document for RAG Ingestion
Convert a document to clean markdown suitable for chunking and embedding in a RAG pipeline.
Convert Invoice to Markdown
Convert a PDF invoice to clean markdown for LLM processing or document pipelines.
Extract 1098 Data
Extract structured fields from 1098 documents.
Extract 1099-MISC Data
Extract structured fields from 1099-misc documents.
Extract 1099-NEC Data
Extract structured fields from 1099-nec documents.
One provider for your entire content workflow
Most document automations chain three or four separate services. Iteration Layer covers extraction, transformation, and generation in one place, and the n8n integration lets you wire those multi-step workflows visually instead of writing glue code.
European by design
Your data is processed on EU-hosted infrastructure and never stored beyond temporary logs. Zero data retention, GDPR-compliant workflows, and a Data Processing Agreement are available for every customer. Learn more about our security practices .
EU-hosted core processing
Application and processing infrastructure runs in Europe, with provider-scope ISO 27001 and BSI C5 evidence documented for procurement reviews.
Zero data retention
Customer files and processing results are not stored after the request. Usage logs are retained for 90 days and automatically deleted.
Clear answers for security teams
Give reviewers the answers they need up front: where files are processed, what is retained, which subprocessors are involved, and how AI inputs, outputs, review gates, and audit records move through each workflow.
Standardize client delivery across projects
When one workflow becomes a repeatable client offer, the partner program helps technical agencies keep client work scoped, billing unified, delivery reusable, and discounts tied to active projects.
Project-scoped client work
Separate client workflows with projects, scoped API keys, usage visibility, and optional budget caps from one organization account.
Reusable delivery patterns
Standardize on n8n, MCP, REST, or SDK workflows instead of rebuilding integration plumbing for every client engagement.
Volume tier discounts
Accepted partners can earn pay-as-you-go discounts as active client projects grow, while each client project stays separately trackable.
Pricing
Start usage-based. Switch to a subscription when your volume becomes predictable.
Usage-based
Graduated pricing. Your effective rate decreases automatically as monthly usage grows.
- No monthly commitment
- Pay only for credits used
- Automatic volume discounts as usage grows
Predictable volume
Fixed recurring credit packs with lower effective credit prices for steady usage.
- Lower effective per-credit prices
- Fixed recurring credit packs
- Predictable monthly budget

One n8n Node for Your Entire Document and Image Pipeline
Most n8n document workflows chain several separate services. The official verified Iteration Layer n8n 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.
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.
