City permitted events (NYC & San Francisco), change detection
Pricing
$1.00 / 1,000 event records
Upcoming permitted public events — block parties, street fairs, farmers markets, parades, races, film shoots — from New York City's and San Francisco's own open-data APIs, in one schema with per-run change flags (new, updated, removed). Official open data only; no contact details are emitted.
Which cities to read. Leave empty for all. Each is the city's own open-data API.
[ "nyc", "sf"]Events that overlap the window from now to this many days ahead. Multi-day permits already in progress are included.
Only output these normalised categories. Empty = all. Filtering never affects change tracking.
[]NYC's feed lists tens of thousands of youth and adult sports field reservations a month. Off by default.
Write (and charge for) only events that are new, changed or removed since your last run. The first run writes everything.
Emit a row for an upcoming event that disappeared from the city feed since your last run (cancelled, denied or rescheduled).
Named key-value store that remembers the previous run for change detection. Use different names for independent monitors.
Safety cap. A capped read still outputs rows but does not update the snapshot or report removals.
