查询免费API，IP阻止
I am using some API which is free. I am using PHP script which is using fopen to download JSON from API. When I make to many requests(eg. 2 requests every minute) API is blocking my PHP server IP. Is there a way to solve it and possibility to make more requests (I don't want to DDoS attack)? Is there better solution than use of many PHP servers with different IP's?

This is a quite abstract question as we don't know the actual api you are talking about.
But, usually, if an api implement a rate limit, it shows this kind of header in it's answer:
- X-Rate-Limit-Limit: the rate limit ceiling for that given request
- X-Rate-Limit-Remaining: the number of requests left for the 15 minute window
- X-Rate-Limit-Reset: the remaining window before the rate limit resets in UTC epoch seconds
Please check the docs (this one is from twitter, https://dev.twitter.com/rest/public/rate-limiting).
