I plan to start to accept Ethereum and some tokens based on it, on a website. The volume would be, I think, at most 10-50 payments a day, at most. And I want to allow a user to know the status of a payment in an automatic manner. For this I'll be sending Http request to the API of etherscan.io every, say, 30-60 seconds.
I'm aware of the limit of etherscan which is over 5 requests per seconds. My volume, even if it was 1 req/sec, would be way less than that, that is, it'd work fine.
Are there any downsides or thing to pay attention to that I've overlooked?
