App lookup

Metadata for one app (by trackId) per storefront, including whether the app is available in that storefront at all. With full=true returns the complete iTunes lookup record (description, genres, release dates, minimum OS version, ...) instead of the summary. With subtitle=true also scrapes the App Store web listing for the app's subtitle (which the iTunes API omits) — one extra request per storefront; the keyword field is never exposed by any source and is not returned (evaluate metadata drafts, keyword field included, with the coverage tool).
