Tools · 9

list_apps

Lists the apps and rivals tracked on the account. The appId and storefront codes the other tools want come from here.

list_keywords

Lists an app's keywords in one storefront, with rank, popularity and difficulty.

get_keyword

One keyword: its rank, its scores, its first page and the verdict - should it be targeted, and why. Every unmeasured value comes back null, never zero.

Adds keywords to an app's tracked set in one storefront. Takes a list or a comma-separated paste. They arrive unscored - scoring costs requests to Apple and happens on the collector's schedule - so do…

cusp_actions

The keywords in the 11-30 band, ordered by popularity. The work list a metadata edit pays off on most.
