Send a PDF document to a fax number. WITHOUT API key: returns a Stripe checkout link (pay-per-fax from $2.49) – the fax is sent after the user pays. WITH a Mini/Flex subscription key (sff_...): sends immediately from the subscription quota. The document must be a direct, publicly accessible HTTPS link to a PDF (max. 10 MB). Supported: USA, Canada, Australia, New Zealand and 39 more countries (same list as sendfaxfast.com); premium-rate numbers are not supported. Each call transmits (or, for pay-per-fax, prepares the checkout for) a real fax to the given number. DOCUMENT (exactly one): "upload_id" from create_upload_link (for files on the user's device), "file" (a file attached in ChatGPT, filled in automatically), "document_url" (direct public HTTPS link to a PDF) or "document_base64" (tiny files only, max. 700 KB). For an attachment that is not available as "file", create_upload_link provides an upload link. The result states whether the fax was sent, scheduled or is awaiting payment.
