🟢quote_fax(to, document_url, document_base64)
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(quote_id)
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, and the fax is only sent once you deliberately pay that link. Confirm the cost is acceptable before paying.
