quote_faxread-onlyPrice a fax before committing to anything. Validates the destination and the document, counts pages, and returns an exact total plus a payment link. Free, and sends nothing. Always call this before send_fax.
send_faxcan modifyReturns the authorization instructions for sending a previously quoted fax. THIS ACTION COSTS MONEY AND CANNOT BE UNDONE: paying the returned link transmits a real document to a real fax machine. This tool itself does not charge you — it returns the exact price and a payment link, and the fax is only sent once you deliberately pay that link. Confirm the cost is acceptable before paying.
get_fax_statusread-onlyCurrent delivery state of a fax: awaiting_payment, paid, submitted, sending, delivered, or failed. Failed faxes include a reason you can act on.
get_fax_receiptread-onlyVerifiable delivery receipt for a completed fax. Available once the fax has reached a final state. Use this to prove the workflow finished.
