1. A public Google Trends API. It's currently in Beta, and I can't access it.
2. I'd pay a pretty penny for an API for OpenAI trends (or Anthropic trends), etc. To discover what people are talking about.
3. I'd also love a discord 'trends' API. Again, the main question I'm looking to answer is 'what topic are people talking about right now?'.
What's an API that you wish existed?
There's an API but you have to pay for it. Which I understand on one side, but then: immoscout24 is basicly the biggest player and this is not about consumer goods but one essential good: flats, space to live. So I think it should be mandatory to offer data to everyone who wants to research house & flat pricing/demand data.
2. A generic API for governmental financial transaction data! This would make research so much easiere. There are couple of open data platforms, but look at how scrambled the data is. What is a "financial transaction"? It's basically nothing else then "from, to, amount, reason, category" - I know there's more, but you can break it down, if you want. So, right now every city, district and government is maintaining their own "database". I once tried to analyse EFRE data. Turns out, while this data is basically open and free, every party offers their own weird format, XLSX, CSV and you name it.
I don't see why no one ever tooks the effort to "normalize" such a simple thing - again: I know there's more. But the big picture should simply allow you to create a generic protocol/stream for that kind of data.
