copied!<p>As you are looking to get price and ratings my guess is that you are doing a lookup, not a search, with the iTunes Search API. </p> <p>If that assumption is true then you can "batch" lookup requests by listing multiple ADAM IDs in a query by separating them with a comma. </p> <p>eg.

(900K / 24 hours / 60 minutes == 625)</p> <p>However, if you batch them in groups of 50 then you are looking at about 13 queries / minute (900K / 50 per request / 24 hours / 60 minutes == 12.5). This should be well within the allowed limit.</p> <p>...@Crashalot - if you are doing app recommendations, then we should talk. </p>
