Input

productsarrayoptional

ASINs or Amazon product URLs, up to 1,000 per run. A URL uses the marketplace in the URL; a bare ASIN uses the Marketplace setting.

marketplacestringoptional

The store a bare ASIN is read from.

track_changesstringoptional

true (default) or false. With true, the actor keeps each product's last reading in a key value store in your account, and a later run writes a change row when the price moves or the product goes out of or back into stock.

state_keystringoptional

Optional name for the set of last readings, when you keep several separate tracking lists. Letters, numbers, dots, dashes, underscores.

previous_snapshotarrayoptional

Optional. Rows from an earlier run of this actor, as a JSON list. When given, changes are computed against these rows, not the stored readings.

max_charge_usdstringoptional

Optional. The run stops before a charge that would pass this amount. Summary rows are always returned.

proxy_modestringoptional

auto (default): amazon.com and amazon.ca are read through the Apify proxy pool with residential as the fallback; other marketplaces use residential addresses in that country, because Amazon prices for the delivery country. residential: every product uses residential addresses in its marketplace country and is billed as product-row-local.

Limits

  • Prices and stock are for the location Amazon assigns the address it read from, shown in delivery_location. You cannot choose a zip code in this version: the location form asked for a sign in on the pages tested.
  • A parent listing that needs an option picked has no featured offer. Pass the ASIN of the exact variation.
  • A residential page is about 200 KB on the wire, so a marketplace outside the US and Canada costs more per row.
  • Coupons, member prices, and tax are not added to or taken from the price.
