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

​
