# Quickstart

> Get started with CAS Parser in under 5 minutes. Choose your preferred language.

## Prerequisites

1. **Get an API key** from [app.casparser.in/developers](https://app.casparser.in/developers), or let your coding agent [obtain one automatically](/learn/authentication#from-a-coding-agent-automated)
2. **Have a CAS PDF** ready, or use our sandbox key for testing

<Note>
  For testing, use `sandbox-with-json-responses` as your API key. It returns sample data without consuming credits.

## What you'll build

In this quickstart, you'll parse a CAS PDF and receive structured JSON containing:

* **Investor details** — Name, email, PAN, mobile
* **Portfolio summary** — Total value, account counts
* **Demat holdings** — Equities, bonds, AIFs, ETFs
* **Mutual funds** — Folios with transactions (50+ years of transaction history from CAMS/KFintech)
* **Insurance & NPS** — Policy details and pension accounts

## API endpoints

| Endpoint                       | Description                                  |
| ------------------------------ | -------------------------------------------- |
| `POST /v4/smart/parse`         | Auto-detect CAS type and parse (recommended) |
| `POST /v4/cdsl/parse`          | Parse CDSL eCAS specifically                 |
| `POST /v4/nsdl/parse`          | Parse NSDL eCAS specifically                 |
| `POST /v4/cams_kfintech/parse` | Parse CAMS/KFintech CAS specifically         |

<Tip>
  Use `/v4/smart/parse` for most cases. It automatically detects the CAS type and returns a unified response format.
