It would be very helpful to have an API endpoint that allows programmatically updating the default availability. Specifically, the ability to block certain dates (e.g., holidays or other unavailable days) would be extremely useful. For example, every week an AI agent could send me an email in which I enter which dates I am not available, and then the agent (e.g. through Tasklet.AI) would update TidyCal accordingly. This would save time and integrate with automation workflows.
