query per sec limit on Google Web Search API (Deprecated)

[Kedar Manure]

Hi,

I am trying to access the API through Java. Does anyone if there is a query-per-sec restriction imposed by google..

I am getting a "Suspected Terms of Service Abuse" error if I execute the query frequently..I put a delay still getting the same error...

Google has a Custom Search API but it has 100 queries per day limit and returns max 10 results per query...I want to use more than that free of cost..:)

Thanks

With the deprecated Web Search API, there is no hard query limit, but there is a dynamic throttling mechanism which is triggered by large volumes of requests. There are a few things you can do to increase the throttling thresholds (e.g., include an API key and userip parameter with every request), but there are caveats to that. First, you can't get an API key anymore, and in fact, they may have closed that workaround entirely. Second, the reality is that the API has been deprecated and, as such, Google is gradually clamping down on the number of requests you can submit. So any improvement or workaround will probably have only temporary effects. And the third, biggest caveat is that this all assumes that your use of the API is within the bounds of the TOS. Namely, the TOS prohibit the use of robots, spiders, crawlers, and other applications which submit automated queries (e.g., SEO applications). And to be perfectly frank, I don't recall seeing more than just a couple of applications which ran into the throttling mechanisms which were not of this variety.

Hope that helps.
