I ran this few times and now I get below error. Any idea how to get around this error?

You are being rate limited.
The owner of this website (koinex.in) has banned you temporarily from accessing this website

Koinex set rate limit for ticker API to limit load on their servers. You may have to wait some time between API calls

what is the ticker api rate per minute?

how can I get PHP code of Koinex api?

just came across this and this is great..
I tried modifying the script for the new crypto to crypto pairings.
Can you update your code to sync with the latest api response.

Great job and thanks!

@surd22:
Simply change the line no 47 into

self.price = reply.json()['prices']['inr']
