What are the limitations of scraping google translate?

Question

Parsing

You need to translate a lot of phrases in Google translator. I'm going to make a program that will automatically request the translation of a word and take the answer. But, given that Google has a paid API for the translator, protection should be provided for robots. The robots.txt file says that robots can go to the word translation page, but nothing is said about the frequency of requests, and I wouldn’t want to be banned, there is a lot of data. What can you say about it?

Answer 1

Yandex seems to be still free
