## Important Notes
- API requests are rate-limited to 10 requests per 10 seconds (as prescribed by the (https://developers.transistor.fm/#:~:text=API%20requests%20are%20rate%2Dlimited,to%20use%20the%20API%20again.)[Transistor API reference])
- Dates must be in "dd-mm-yyyy" format
- Page numbers start at 0
- All endpoints support:
- Sparse fieldsets: Specify which fields to return using `fields[resource_type][]`
- Including related resources: Use `include[]` to fetch related resources in a single request
- Include arrays use the format `["resource_name"]`
- Fields objects specify which fields to return for each resource type
- All tools return data in JSONAPI format with proper relationships and metadata
