Sorry for not getting this right away: but are you solely matching the string to a merchant and then returning all of the (already-stored) information for that merchant? Or are you joining that to some other public record of transactions to get additional information?

In other words, in the example on the homepage, is all of the returned data except the dollar amount static data from a DB once you have matched the transaction to the merchant (Google in this case)?

And then sort of unrelated, what are your long-term plans? If step 1 is perfectly hydrating a merchant to a transaction, what is step 2 (if there is one)?
