Originally I had Twitter support, but they changed the API around and it ended up not working any more, see the project blog for more info: https://blog.trendbowl.app/
The Pro subscription to the API now seems to be $5000 per month!
My current project is TrendBowl (https://www.trendbowl.app) which summarises trending entities across multiple sources on the web, including Mastodon and Wikipedia. On a 24 hour basis you can see which terms are relevant in different languages and sites.
It is implemented in Go, Python and JS, with support from Postgres, TimescaleDB and Kubernetes.
