Twitter’s API issues have frustrated developers in each of Twitter’s new API access tiers. Those with Basic or Pro plans — paying $100 and $5000 a month for API access, respectively — have experienced unannounced changes to their plans, numerous bugs, and often receive zero customer support. And developers shelling out for Twitter’s Enterprise API Plan, which starts at $42,000 per month, are experiencing sudden outages and disappointing service considering the money they’re paying.
I don’t do this work but from what I heard from my uni, librarians are sharing guides to analyze twitter from web archive. So I’m not sure whether there are researchers that actually pay, or at least at that full price. Even reddit/pushshiftapi makes some exceptions for researchers and moderators, for the time being.
