We've just been alerted to an issue with the API billing system. Some accounts that have paid for API usage were not credited. We deeply apologiese for this. We have increased daily API usage limits to 2500 calls/day until we resolve this issue. We are also going to be refunding any recent purchases. Thank you so much for your understanding.
