More API related than Alby Hub, but:
1. Bolt11 decode only works for Alby generated codes, it’d be cool if it worked for any
2. Easy API endpoint to pay an npub or Lightning address
3. Can you figure out a way to make payment splits work on Nostr? 
For example: I have a bot that translates content and I want to share any zaps made to that bot with the original content owner

Other than that, keep crushing 💪
