And you thought that faxing was a thing of the past. At Phaxio, it's so new that it doesn't even use XML. The JSON-only Phaxio API lets you send faxes for 7 cents per page and you can get a confirmation of each fax’s total cost through the API itself. Account level information is available as well. Detailed information about all faxes sent over a specific time period can also be retrieved from the API.
