Archive modes

Besides a live query (mode: live, the default), the Actor can read its own archive. The archive is a snapshot Oct 17, 2026 03:08 ADT; refreshes may be added later.

mode	Extra input	Returns
changesSince	since (YYYY-MM-DD)	permits added, changed or removed on or after that day in the snapshot Oct 17, 2026 03:08 ADT; removed ones listed (ID + _deletedOn only, not charged) in the run's key-value record DELETED
asOf	asOf (YYYY-MM-DD)	each record as it stood at the end of that day in the snapshot Oct 17, 2026 03:08 ADT
history	ids (up to 1,000)	every archived version of those records, oldest first (snapshot Oct 17, 2026 03:08 ADT)
archiveExport	–	the current version of every archived record (snapshot Oct 17, 2026 03:08 ADT)

When refreshes are added later they are compared against a complete pull; until then the archive is a snapshot Oct 17, 2026 03:08 ADT. Permits that disappear from the source are kept only as an ID and the date they were removed. Privacy rules are applied again when the archive is read, so a rule tightened later also covers older rows. The normal filters, maxItems and fetchAll apply in every mode, and each row returned is billed at the normal per-result price. Archive modes return at most 50,000 rows per run.

Large pulls

Apify stops a run once its charges reach the account's per-run limit (about $85 by default, which is about 28,000 rows at $0.003). For more than about 25,000 permits, split the pull into several runs by date range (dateFrom / dateTo) or by another filter, and combine the results.

Privacy

• The source has no owner, applicant or contractor fields, and work types are short codes (no free text).
• Most permits are for homes, so the civic number is dropped (only the street is kept, e.g. "DUNN ST"), latitude and longitude are rounded to 2 decimals (about 1 km), and the parcel ID is not output.
• Group homes, bed & breakfasts, and boarding, lodging and rooming houses also lose their street and location (locationWithheld: true): 61 permits on the Oct 16, 2026 data.

Source and licence

• Source: City of Niagara Falls open data, layer "Niagara Falls Completed Building Permits" (FeatureServer layer 0), read through the ArcGIS REST API in pages of 2,000 with a 2-second pause (5 requests for the full set).
• Licence: Open Government Licence – Niagara Falls (based on version 1.0 of the Open Government Licence – Ontario), linked from the dataset's licence field. It grants use "including for commercial purposes" with attribution. Every record carries "Contains information licensed under the Open Government Licence – Niagara Falls." The licence does not cover personal information.

Pricing

$0.003 per result, no start fee. The full dataset costs about $24.55.

Limits

• Not current: the city's layer ends at December 2023. Each run reads the live layer, so newer permits appear if the city adds them.
• Only completed (Final) permits; no construction value. 3 permits have no date.
• The layer has no per-record edit date (only a layer-wide last-edit time, March 2025), so it cannot be asked only for records changed since a date.
