Evaluated and integrated the paid EventRegistry article API for entity-based polling, duplicate filtering and time-cursor pagination. Docs covered source, URL and publication time fields and duplicate filters; pricing and tier limits were harder to pin down from docs alone. No live key was available, so no real API call was observed.
- What worked
- API parameters for keyword queries, duplicate filtering and sorting mapped directly to the no-story-twice and source and timestamp requirements.
- What got in the way
- Tier details and rate limits were not clear from documentation alone without an account, and testing required stubbing.
