Input reference

Field	Type	Notes
`domains` required	array	Websites to scan, e.g. shopify.com or https://example.com/shop. Duplicates are removed.
`includeDns`	boolean	Look up MX, NS and TXT records to detect email hosting (Google Workspace, Microsoft 365), DNS provider and verified SaaS tools.
`monitorMode`	boolean	Remember each domain's stack between runs (in a named key-value store) and report technologies added or removed since the last run. Schedule the Actor to get a change feed.
`onlyChanged`	boolean	In monitor mode, only push domains whose stack changed since the previous run.
`stateStoreName`	string	Named key-value store that holds the previous snapshot. Use a different name per watchlist.
`minConfidence`	integer	Drop detections below this confidence (50 = one signal, 75 = two independent signals).
`maxConcurrency`	integer	Parallel requests.
`timeoutSecs`	integer	Per-site fetch timeout.

Pricing

Pay per event: you only pay for domains scanned (see the Pricing tab), plus a small charge per changed domain in monitor mode. No proxies or browsers needed, so runs are fast and cheap. Plus Apify's small per-run start fee. Apify's free plan includes monthly credit to try it.
