Add document extraction to your SaaS product

REST API & Node.js SDK No ML infrastructure First integration in minutes
The Problem

Building document parsing in-house is expensive and slow

Your users need to extract data from documents inside your product, but building reliable OCR and extraction from scratch requires ML expertise, significant infrastructure, and months of development time.

Even with cloud OCR APIs, the raw text output still needs custom parsing logic for every document type. Maintaining extraction accuracy as document formats evolve adds ongoing engineering overhead.

6-12 months to build reliable in-house extraction

ML infrastructure costs are high and unpredictable

Every new document format requires custom parsing logic

Hiring ML engineers for a non-core feature is hard to justify

The Solution

Embed extraction with a few lines of code

Use the Parselyze API or Node.js SDK to add document extraction to any endpoint in your application. No ML knowledge, no training data, no infrastructure to manage.

First extraction in minutes

One npm install, one API call. The Node.js SDK handles auth, file upload, and polling.

HMAC-signed webhooks

Every webhook delivery is signed. Verify authenticity server-side before processing.

Multi-tenant ready

Each API key is scoped per project. Manage keys per customer or environment.

Custom templates per document type

Define different extraction schemas for invoices, contracts, receipts, all from one account.
