# Build with the Paragraph API & SDK

> Integrate Paragraph’s API & SDK to access post data, user profiles, coins, and more.

Paragraph provides a powerful API for building applications that interact with onchain publishing. Access publication data, manage posts, work with coins, and integrate user profiles - all through a simple REST API or our TypeScript SDK.

### Important notes

* The API is in alpha. There may be breaking changes until we finalize the design.
* The API is rate-limited. If you're hitting rate limits & want to request an increase, reach out to [support@paragraph.com](mailto:support@paragraph.com).
* Some endpoints require authentication via an API key. You can generate one in your [publication settings](https://paragraph.com/settings/publication/#developer).
