Request limit 
There is no hard and fast limit on read requests, but we ask that you be considerate and try not to take the site down. We also reserve the right to unceremoniously block you if you do endanger the stability of the site.
If you make your requests in series rather than in parallel (i.e. wait for the one request to finish before sending a new request, such that you're never making more than one request at the same time), then you should definitely be fine. Also try to combine things into one request where you can (e.g. use multiple titles in a
titles parameter instead of making a new request for each title. Or use "generator" if possible instead of making a request for each result from another request).
Parsing of revisions 
While it is possible to query for results from a specific revision number this is an expensive operation for the servers. To retrieve a specific revision use the 'oldid' parameter, example:
Use maxlag parameter 
If your task is not interactive (i.e. A user is not waiting for the result) you should use the maxlag parameter. This will prevent your task from running when the load on the servers is high.
