Hi, I would like to work on this issue.

Plan:

• Add a practical API usage cookbook with copy/paste request examples and representative responses.
• Cover authentication setup plus common notification workflows end-to-end.
• Include troubleshooting tips for common API errors and local testing issues.
• Keep the guide aligned with the existing project docs so contributors can test endpoints quickly.

I will wait for assignment before opening a PR so this follows the GrantFox workflow.
