Getting started
LangParse is a document-intelligence API. Send a document, get back clean, structured data — with per-field confidence, a review queue for anything low-confidence, and tools to measure accuracy over time.
What you can do
Section titled “What you can do”- Parse documents and scans in almost any format — PDF, images, and more.
- Define the fields you want back as a model (a document type + its schema), or extract schemaless and let LangParse infer the fields.
- Extract reliably across variable layouts and 100+ languages, returning a consistent set of fields with confidence scores.
- Route & split multi-document files, classify them, and send each part to the right model automatically.
Pick your path
Section titled “Pick your path”- Just want structured data fast? → Quickstart — parse your first document in a few minutes.
- Want the mental model first? → Core concepts — models, async parsing, confidence, routers, and keys.
- Building an integration? → API Reference — every endpoint, parameter, and response, with a live “try it” console.
Two ways to extract
Section titled “Two ways to extract”| Model-based | Schemaless | |
|---|---|---|
| Schema | You define the fields | Inferred automatically |
| Best for | Repeatable document types | One-offs, exploration, the live demo |
| Endpoint | POST /api/v1/models/{modelId}/parse |
POST /v1/extract |
Everything is scoped to an organization with a data-residency region you choose (US or Australia today). Sign up free to get a key, then head to the Quickstart.
