add potential exception data to web apis

[petermakeswebsites]

What would you like to see added to BCD?

It would be fantastic to be able to know what web apis might throw, and what errors they might throw. I noticed that MDN has this data on their website (example). Yet that data does not seem to be available in BCD. It would be fantastic to have that data available without needing to do web scraping.

How impactful do you think this enhancement will be?

It would be great because it would allow tools to automatically catch error handling. For example, people can generate libraries programmatically based off of the data here to let the developer know when a potential error may go unhandled, mapping particular exceptions them to particular api calls.

Do you have anything more you want to share?
