Buy credits at https://www.sendthisfax.com/en/credits.\n- Without an API key: sender_email and billing_country are REQUIRED and the tool returns a checkout_url the USER must pay in a browser; the fax is sent automatically once paid.\n\nIn both modes, poll get_fax_status until status reaches \"delivered\" or \"failed\" (failures after payment are auto-refunded).\n\nFor integration testing, +19898989898 is the designated test recipient number.\n",
