Right now each account is limited to 20 VIN requests a month, we are looking to take it slow and prevent abuse. If you do need more VIN decodings a month, feel free to let us know at Mr. Quotey, we'd be happy to up the max for your account.
Where to next?:
It is too soon to really tell. We'd like your feedback and to know if this service is useful. If it gets enough buzz, we would probably pursue it a bit more and drop the monthly limitations.
