## Tools (3)

- `check_site`: Бесплатно проверяет сайт по 152-ФЗ или перед подключением приёма оплаты. Возвращает находки (fail/warn/ok/info) и, если найденное исправляют наши документы, check_id для create_checkout. Не передавайте персональные данные: нужен только адрес сайта.
- `create_checkout`: По check_id из check_site и выбранному товару возвращает ссылку на страницу нашего сайта. Человек открывает её, видит результат проверки, указывает e-mail, принимает оферту и платит сам. Ссылка действует 48 часов. Агент оплату не проводит.
- `get_offer`: Что продаётся, цены в рублях, что входит, как платит человек, ссылки на оферту и условия возврата.
