# Introduction

BlinkID Verify is a document verification solution that extracts data from documents, and verifies their authenticity and liveness.
It is a superset of [BlinkID](/blinkid).

BlinkID Verify has two components, the API and the client-side SDK; using both is recommended for optimal performance.

### API

The BlinkID Verify API handles document verification.
At a high level, it's a RESTful API that takes in images of a document and returns a JSON response with the verification results plus extracted document data.

The API can be accessed as a [cloud API](/verify/quick-start) or as a [self-hosted container](/verify/deployment).

It can be used standalone, but for best results, use it with the client-side SDK.

### Client SDK 

The client-side Verify SDK captures document images, optimized for the Verify API.
It ensures any images sent to the API are high quality and verifiable, and provides a smooth user experience.

The SDK is available for [iOS, Android, and web](/verify/sdk).
