We specialize in zap testing. Can u provide an example of an npub who you consistently can’t zap? We can do some testing and find out what the issue is.

This is the message Amethyst gave me..

Could not fetch invoice from https://getalby.com/lnurlp/chiangmai/callback: Recipient wallet error. Please contact the recipient.

nostr:npub1c9r9lad84kpqwnh09u58vdzwnfsnxcr7a40uf5ulkpdguq4667jsgaxu4k Yep, just tried him, his node is not producing an invoice. Here is the deal with nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm lightning addresses, according to our findings.

1. "Alby Pro Cloud" ( https://getalby.com/pricing ) -- should be VERY reliable. You should NEVER have a problem getting zaps if you do this.

2. If you self-host your own Alby node, then things get more complicated. Is your computer online 24/7? Is your internet connectivity really good? (And lots of people **think** their connectivity is good, but in reality, their internet goes up and down, and they don't notice.)

I'd be willing to bet that nostr:npub1c9r9lad84kpqwnh09u58vdzwnfsnxcr7a40uf5ulkpdguq4667jsgaxu4k might be in situation #2.

Self-hosting is good for other reasons (decentralization of the network). But it is challenging to get zaps.

This is definitely helpful to know

I’m building a PWA nostr client that primarily focuses on short form video events and run into issues when trying to directly zap users with different LNURLs that have CORS-restrictive policies

how do you deal with CORS issues when requesting invoices from different origins?

Are there any specific tools or libraries that you recommend for handling CORS issues in a browser-based application?
