# Introduction

> Parse documents and extract structured data with grounded citations.

Parsimmon is a document intelligence API for teams that need reliable extraction from real business documents.

Send Parsimmon a PDF or document file. The API creates a run, processes the file, and returns normalized output with citations back to the source document. Citations include page and bounding-box coordinates so your product can show exactly where each answer came from.

Use Parsimmon for:

* Parsing documents into structured blocks.
* Extracting fields from invoices, contracts, forms, and operational paperwork.
* Building review workflows where every extracted value stays grounded in the source.

The public API is versioned under `/v1`. Processing requests return immediately with a run record, then clients poll the run until it succeeds or fails.
