Process

How It Works

Three steps from document to clean, structured data.

01

Send your document

POST a PDF, image, ISDOC, ZUGFeRD or other business document to the API endpoint. Multipart or base64.

02

Documiner extracts the data

Documiner identifies the document type and extracts all relevant fields — vendor, line items, totals, dates, and more. Native parsers handle ISDOC and ZUGFeRD directly.

03

Receive structured JSON

Get back a validated, typed JSON object ready to push into your ERP, accounting system, or custom integration pipeline.

Capabilities

Everything You Need

Built for production integrations. Flexible enough for any setup.

API-first design

A single REST endpoint accepts your document and returns structured JSON. Integrate in minutes, not weeks.

Fast turnaround

Most documents are processed in under 3 seconds. Batch processing available for high-volume use cases.

Zero document storage

Documents are processed in memory and never persisted to disk. Your data stays yours.

AI-powered extraction

Documiner uses AI to extract data from unstructured documents. Native parsers handle structured formats like ISDOC and ZUGFeRD with 100% accuracy.

Native e-document formats

Beyond AI extraction: native parsers for ISDOC and ZUGFeRD deliver perfect accuracy on structured e-invoice formats.

EU data processing

All processing happens on servers inside the European Union. Fully GDPR-compliant by design.

On-premises deployment

Deploy as a Docker container or standalone binary inside your own infrastructure. Full data sovereignty.

User & token management

Create users, generate API tokens, and set per-user permissions. Built for multi-tenant integrations.
