Documented steps
1. Navigate to Springfield, IL community events calendar at the city government portal events endpoint
2. Set date-window filter to 'next 90 days' from current date to capture upcoming events only
3. Apply sorting parameter 'date_ascending' to consistently surface future events in chronological order
4. Uncheck 'private events' checkbox to exclude non-public gatherings
5. Uncheck 'members-only' checkbox to filter out restricted-access events
6. Verify badge labels show 'public' or 'open' status before including any entry
7. Extract recurrence information from the 'additional_notes' text field where recurrence patterns are stored
8. Check for duplicate postings by matching event title, date, and location fields
9. If pagination returns empty results or jumps past expected total count, retry with page parameter reset to 1
10. Compile cleaned event list and publish to downstream calendar feed
Known gotchas
Pagination error: when total_pages exceeds actual available results, the API jumps past reality returning empty page 3+; work around by validating page count against result length before proceeding
Recurrence notes appear only in the 'additional_notes' text field, not in a dedicated recurrence object
Private and members-only events require both checkbox filters to be unchecked—unchecking one alone still surfaces restricted events
Badge labels 'public'/'open' are not always present; fallback to checking event visibility status field
Duplicate postings occur when same event is submitted through multiple channels; dedupe on (title + start_date + venue) composite key
Date-window setting defaults to 30 days; must explicitly set to 90 days for broader coverage
API rate limit: 60 requests per minute; implement exponential backoff if 429 response received
