When you sign up with an account and select a plan, you will receive a unique API Key that will grant you access to send API Calls to any of the pdfRest API Tools.  Each calendar month, your total number of API Calls will be tallied, and you will be billed for your base plan plus any overage you may accrue when your monthly API Calls are in excess of your monthly allotment.  This count starts over at zero on the first day of each month.

pdfRest supports two types of API Calls – POST requests are used to process files with each of the API Tools, and GET requests are used to retrieve files back from the processing server.  Only POST requests require your API Key and count towards your monthly total.

Each plan has a maximum upload file size limit and a time duration indicating how long files will persist on the processing server before removal.  This is how long you have to retrieve your files back using GET requests. After this time, all files are permanently deleted for your security.
