4 tools

• quote_fax

  Price 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_fax

  Returns 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

• get_fax_status

  Current delivery state of a fax: awaiting_payment, paid, submitted, sending, delivered, or failed. Failed faxes include a reason you can act on.

• get_fax_receipt

  Verifiable delivery receipt for a completed fax. Available once the fax has reached a final state. Use this to prove the workflow finished.
