create_faxPrepare a fax for a person to send with PayPerFax, the pay-per-fax service: no account, no subscription, one payment for one fax. A common use is a letter or a form for the IRS, a doctor, a court, an insurer or a landlord. The tool does not send the fax and does not charge. It returns a link for the person. The person opens the link, sees the preview and the price, and pays in the browser. Then t
get_fax_statusread-onlyRead where a fax is. Give the id from create_fax, or an address of the fax: the status address from the tracking prompt of the person, or the address of a page of the fax. "status" is pending, delivered, failed or expired. While it is pending, "stage" says more: rendering (we prepare the pages), awaiting_payment (the person did not pay yet; "pages" and "price" are given, and they can still change)
list_supported_formatsread-onlyList what PayPerFax can fax, and the limits: the text that create_fax takes, the file types that a person can add on the form or that a shell can send to the HTTP call, the sizes, and the languages.
