# Introduction

> Extract structured data from any invoice PDF in seconds.

# Welcome to Parzo

Parzo is an API that extracts structured data from invoice PDFs — any layout, any language, no templates required.

Send a PDF. Get back clean JSON. That's it.

## Who is Parzo for?

* **Developers** building accounting agents, expense tools, or AP automation
* **Software houses** that need invoice parsing embedded in their products
* **AI agent workflows** on n8n, Make, LangChain, or Claude

## How it works

<Steps>
  <Step title="Send a PDF">
    POST your invoice to `/v1/extract/invoice` with your API key.
  </Step>

  <Step title="Get a job ID">
    Receive a `job_id` immediately. Processing happens asynchronously.
  </Step>

  <Step title="Receive structured JSON">
    Poll `/v1/jobs/:id` or receive the result via webhook.
  </Step>
</Steps>

## What you get back

Every extraction returns a consistent JSON schema with:

* **Vendor** — name, VAT number, address, IBAN
* **Buyer** — name, VAT number, address
* **Invoice** — number, date, due date, currency
* **Financials** — subtotal, tax rate, tax amount, total, discount
* **Line items** — description, quantity, unit price, amount
* **Validation** — confidence score, warnings, scanned document detection
