Blockchain API для определения подтверждений транзакций

Я пытаюсь определить, была ли подтверждена транзакция в биткойн-блокчейне или нет. Я получил доступ к представлению JSON транзакции из blockchain.info используя этот url: https://blockchain.info/tx/62f9419e56ac1b628840aaf52307867f9856d7a52b3c1d945a9938a3021cbf2c?show_adv=false&format=json

Я не могу найти ничего в ответе, который указывает, сколько подтверждений он имеет...
