## Using the OpenAPI specification

The OpenAPI specification can be used to:

* **Generate client libraries** - Use tools like [OpenAPI Generator](https://openapi-generator.tech/) to create SDKs in your preferred language
* **Explore endpoints** - Import the spec into tools like [Postman](https://www.postman.com/) or [Insomnia](https://insomnia.rest/) for interactive testing
* **Validate requests** - Use the schema to validate your API requests before sending them

<Note>
  Our documentation and OpenAPI specification are constantly updated to reflect the latest version of our RESTful API. Always use the latest version for the most up-to-date endpoint information.
