You need to understand that no one can give a 100% guarantee that the data on the endpoint will be extracted, since many elements are involved in this mechanism, such as: response time and server availability, response time and proxy server availability, account blocking and freezing, the availability of the Instagram server itself, changing the mechanism of work by Instagram itself.

Therefore, at the moment I closely monitor the work of the API, for parsing I use the technology

[POOL1->(search->[error]->repeat(POOL1)->response)]
[POOL1->(search->[success]->response)]

which in 90% of cases gives a successful response

Thank you for using!
