How this service works
Accepts three forms of recipient. A bech32 lnurl is decoded to its callback URL, a Lightning address is resolved through the well-known lnurlp path, and a Nostr public key is resolved by reading its kind 0 profile from relays and taking the lud16 or lud06 field it publishes.
Output
A Lightning Network payment request (invoice) string that can be paid immediately, derived by resolving the recipient's LNURL callback URL, Lightning address well-known path, or Nostr kind 0 profile lud16/lud06 field.
Example use cases
Pay a Nostr user via their profile
“I want to send a tip to the Nostr user with public key npub1xyz789... — can you get me a Lightning invoice for 21000 millisatoshis by resolving their profile's Lightning address?”
Resolve a Lightning address to invoice
“Get me a payable Lightning invoice for the Lightning address user@domain.com for 50000 millisatoshis.”
Decode bech32 LNURL to invoice
“I have this bech32 LNURL: lnurl1dp68gurn8ghj7... — can you decode it and generate a Lightning invoice for 10000 millisatoshis?”
Technical details
Endpoint
POSThttps://nostr.halowerk.com/lnurl-invoice?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to obtain a Lightning invoice for a recipient identified by a Nostr public key, a Lightning address (user@domain.com), or a raw bech32 LNURL string. It is the right choice when you want a single endpoint that handles all three LNURL recipient formats, especially when the recipient is a Nostr user whose Lightning info is embedded in their kind 0 profile on relays.
Side effects
- Nostr public key has no lud16 or lud06 field in kind 0 profile — returns resolution error
- Relay lookup fails or returns no kind 0 event for the given public key
- Invalid or malformed bech32 LNURL input — decoding fails
- Lightning address domain's well-known LNURL path is unreachable or returns an error
- LNURL callback server returns an error or invalid invoice
- Amount outside min/max sendable range specified by the LNURL endpoint
