Data and calendar feeds

Each public data endpoint produces a normalized result that can be projected into supported formats. ICS is one projection, not the internal data model.

Use:

• ICS or WebCal for subscriptions.
• JSON for application code.
• XML or text for constrained and legacy clients.
• CSV, TSV, NDJSON, or JSONL for line-oriented and tabular processing.

The OpenAPI reference is authoritative for operation parameters and responses.
