A while ago I was looking for an API that would give me the calendar date that quarterly earnings were reported historically, ideally for all public companies (but a large subset like the S&P500 would do). Do you know if anyone tracks this data, and if so where I might find it?
Yeah, that should be possible with a moderate amount of work. We probably won't support it very soon, but I would start with Intrinio, which is relatively easy to work with compared to some of the bigger providers:
Not the OP but I have side projects in similar veins. I didn't find any great sources for this, so I ended up scraping Zacks and similar sites; both for backfill and future.
If anyone found something easier, I'd certainly be curious as well.
