Api Endpoint

nostr.halowerk.com

Takes any public NIP-19 identifier or a 64-character hex value and returns every representation it can be expressed as. A decoded nprofile or nevent yields not only the key or event id but also the relay hints, the author and the kind that the TLV form carries — precisely the fields that make a follow-up query targeted, and precisely what is lost by code that only handles npub.
