Frequently asked questions

What is a document extraction API?

A document extraction API accepts document files and returns structured data from them — named fields like merchant, total, date, currency, and line items — as a JSON response rather than raw text.

What document types does DocuParse API support?

DocuParse API is built for receipts, invoices, and business documents in PDF, JPG, PNG, and CSV formats.

How is this different from OCR?

OCR converts images to raw text. DocuParse API goes further: it identifies document type, locates relevant fields, extracts values, and returns them as a structured JSON object your application can use directly.

Can I see extraction results in a dashboard?

Yes. All extracted documents are visible in the DocuParse dashboard with their full extraction results, document type, and structured fields.

How does DocuParse handle difficult or low-quality documents?

DocuParse handles difficult scans, unusual layouts, and non-standard formats automatically. The extraction runs and returns the same named fields regardless of document quality.

How do I get started?

Sign up for a free account, generate an API key from the dashboard, and send your first document to the /api/v1/extract endpoint. The free tier includes 20 documents/month with full API access and no credit card required.
