}Limitations
- Search ranking and index refresh latency are undocumented. This is not a complete App Store index.
- First-seen dates start with our observations; they are not release dates.
- Rating counts are storefront observations, not text review counts, downloads or revenue.
- A successful lookup with no record means not returned by this source; it is not definitive proof of delisting.
- An app absent from the bounded candidate sample has unknown current availability.
- Price filters apply to each storefront currency without currency conversion.
- No metadata resale license or payout eligibility is asserted. Commercial publication requires the owner launch gates.
