Hi Zaver, A 420 response from the Search API means you have been rate limited. What you should do is stop making requests and then try again 30 seconds later. If you still get 420, wait 1 minute. Continue doubling the time you wait until the 420 stops and you get results. Then gradually increase your request rate again.
For extra back off magic add a little jitter (e.g. a random number of seconds between say 0 and 30) to the doubled wait times. Hope that helps, @themattharris Developer Advocate, Twitter http://twitter.com/themattharris On Tue, Feb 22, 2011 at 12:29 AM, zaver <zave...@hotmail.com> wrote: > Hello, > > I am using the search api with multiple keywords (120 keywords) using > curl (curl_multi_init etc.), querying the api every 5 mins and i need > some help on how to handle some of the response codes. > Specifically: > > 420 -> i get this error on some of my keywords not all.
