URLs to watch

urls

Required

One or more URLs to check for content changes. Each URL is fetched, hashed, and compared against its previous hash (stored in the actor's KeyValueStore). Accepts plain strings, { "url": "..." } objects, or { "url": "...", "selector": "..." } to scope just that URL to a CSS selector (e.g. watch only a price div on one page while monitoring the full body on another). A bad/no-match selector falls back to full-page text with a loud warning — it never silently reports a phantom change.

Type:array

Default CSS selector (optional)

defaultSelector

Optional

Fallback CSS selector applied to any URL in the list that doesn't set its own per-URL selector. Example: ".pricing-table". Leave empty to use the legacy selectors field (or full page) instead.

Type:string

Legacy CSS selectors (optional)

selectors

Optional

Deprecated in favor of per-URL { url, selector } entries or defaultSelector — kept for backward compatibility. Applied only to URLs that have no per-URL selector and no defaultSelector. If empty, the full page body text is monitored. Example: [".pricing-table", ".product-description"]

Type:array

Minimum change ratio (noise threshold)

minChangeRatio

Optional

Ignore small changes. 0 (default) reports every content hash difference, same as before. Set e.g. 0.02 to only report/charge a change when at least 2% of the tracked text differs from the previous check — useful for pages with small rotating widgets, ad slots, or view counters that would otherwise trigger noisy false positives.

Type:number

Minimum:0

Maximum:1

Default:0

Max URLs to check

maxItems

Optional

Maximum number of URLs to check in this run. 0 = unlimited. You are charged per check and per detected change.

Type:integer

Minimum:0

Maximum:100000

Default:50

Use residential proxies

useResidentialProxy

Optional

Switch to residential proxies if datacenter IPs are blocked. Increases cost but may be needed for bot-protected targets.

Type:boolean

Default:false
