I'm looking for a good API to pull LN/Blockchain data from for my newly released Bitcoin Metrics, Android app. Suggestions? Currently, I'm pulling from coingecko.com, but I've now added all the metrics they offer.

you can host your own blockchain api server if you have a full node. I think core has a rest interface

https://amboss.space API for more LN metrics

Sweet deal, I'll check these out for sure
