Access to Google Scholar BiBTeX data

Thank you for this API!! It is good to see that at last someone is working on this officially. I've tried scraping Google Scholar via some code I wrote using Swift and whilst I was able to parse each entry, my code was temperamental because of Google's anti-robot mechanisms. Because I was using Swift's internal http client, I had issues with some cookie information that caused Google Scholar to invoke reCaptcha during my runs.

Whilst this issue pertains to extending the API to enable access to the BiBTeX reference information (and other formats for that matter), I would also like to point out that (often) the reference data on Google Scholar is not as accurate as it could be. For example, using the playground to find "M-Coffee: combining multiple sequence alignment methods with T-Coffee" and comparing the returned data with Google Scholar's BiBTeX information as well as Oxford's Academic Database, the discrepancies will be clear:

We show that the procedure is robust to variations in the choice of constituent methods and reasonably tolerant to duplicate MSAs. We also show that performances can be improved by carefully selecting the constituent methods. M-Coffee outperforms all the individual methods …",
