Just a suggestion, but it seems like n requests in t for free would be a good model too. eg: Free 60 requests free per hour. 600 free test transactions is great, but for ongoing development the sandbox idea or rate limiting for a free plan seems preferable to us 'hackers'

Edit: edited n of free requests per t in eg

Cool, thanks for the suggestion. The sandbox should be rolled out by the end of the week. Any reason why you put 'hackers' in quotations? Does it bother you that we use the word?

Unless the title changed, I don't see quotes anywhere. There is an apostrophe after the word in the HN title, but that's there to show possession (it's their hands).
