Insighthread News API: All Event Categories Reference

Every event returned by the Insighthread News API belongs to one of 35+ structured categories. Insighthread’s extraction pipeline maps each SEC filing — down to the specific item section — to a category, so you always know what kind of event you’re handling before you read a single word of the summary. Categories are available as filter parameters on the /events endpoint and are included in the event_type field of every event object.

Filtering by Category

Pass the event_type query parameter to the /events endpoint to receive only events matching a specific category. URL-encode values that contain spaces or special characters:

curl "https://api.insighthread.com/v1/events?event_type=FDA+Approval%2FRejections" \
  -H "Authorization: Bearer YOUR_API_KEY"

You can combine event_type with other filters — such as ticker, impact_min, or from / to date range — to narrow results further. See GET /events for the complete parameter reference.

Use the event_type filter to subscribe your platform to only the categories relevant to your users. An equity trading desk, for example, might filter to Mergers and Acquisitions, Bankruptcy/Liquidation, and Corporate Earnings, while a pharma-focused fund would add FDA Approval/Rejections, Drug Trial/Clinical Data, and Drug Updates.
