I would like to create a simple online service, that needs AdWords API access to do some keyword search.
The subscribers of my service would have to provide their AdWords API developer key and token and so on .. to use all the features of my service. This way our server would connect to the AdWords API server, would collect all the necessary data, do some proprietary calculations and return the data to the subscriber.
So my questions:
- Can I use the AdWords API like this?
- Is it legal?
- Is there any rate limit to the Google API servers? If there is .. is it the rate limitation belongs to a specific client IP address or it belongs to the client developer key? Basically do I need to use some kind of proxy to serve many of my subscribers?
Thank you very much for your help, Peter
