# SDKs Overview

> Official KeyPort SDKs and framework integrations for validating license keys in your application.

KeyPort provides official SDKs for the most common server-side runtimes and frameworks. Each SDK wraps the live public API so you can validate and look up license keys without constructing HTTP requests by hand.

## Covered API operations

All SDKs support the following two endpoints:

* `POST /api/v1/validate` — validate a license key
* `GET /api/v1/license/:key` — retrieve full license details

## Configuration styles

Every SDK guide shows both ways to supply your API key:

* **Inline** — pass the key directly when initializing the client
* **Config file** — load from a `keyport.json` file on disk
