v1.1.0 - Single-Event Headlines Endpoint

New per-event headlines endpoint (/headlines/event/{event_id}) replacing the batch endpoint for significantly improved caching performance. The batch /headlines/events endpoint is deprecated with a planned removal date of 2025-10-15.

Added

• New single-event headlines endpoint /v1/headlines/event/{event_id} for retrieving headlines for a specific event
  • Benefits: Responses can be cached per event ID, resulting in better cache hit rates and faster response times
  • Usage: GET /v1/headlines/event/123 returns headlines for event ID "123"

Deprecated

• Batch headlines endpoint /v1/headlines/events will be removed on 2025-10-15
  • Migration Strategy:
    • Option 1 - For insights workflows: Use show_events=true parameter on insights endpoints to get events and headlines together
      • Before: GET /insights/analyst/{ticker} → GET /headlines/events?event_ids=123,456
      • After: GET /insights/analyst/{ticker}?show_events=true (single request with events and headlines)
    • Option 2 - For direct event queries: Use individual calls to /v1/headlines/event/{event_id}
      • Before: GET /v1/headlines/events?event_ids=123,456
      • After: GET /v1/headlines/event/123 and GET /v1/headlines/event/456
  • Note: The deprecated endpoint remains fully functional until removal date
