-                    LNURL is a range of lightning-network standards that allow
-                    us to use lightning-network differently. An LNURL-pay is a
-                    link that wallets use to fetch an invoice from a server
-                    on-demand. The link or QR code is fixed, but each time it is
-                    read by a compatible wallet a new QR code is issued by the
-                    service. It can be used to activate machines without them
-                    having to maintain an electronic screen to generate and show
-                    invoices locally, or to sell any predefined good or service
-                    automatically.

-                  <p>
-                    Exploring LNURL and finding use cases, is really helping
-                    inform lightning protocol development, rather than the
-                    protocol dictating how lightning-network should be engaged
-                    with.

-                    <b>WARNING: LNURL must be used over https or TOR</b><br />
-                    LNURL is a range of lightning-network standards that allow
-                    us to use lightning-network differently. An LNURL-pay is a
-                    link that wallets use to fetch an invoice from a server
-                    on-demand. The link or QR code is fixed, but each time it is
-                    read by a compatible wallet a new QR code is issued by the
-                    service. It can be used to activate machines without them
-                    having to maintain an electronic screen to generate and show
-                    invoices locally, or to sell any predefined good or service
-                    automatically.
-                  </p>
-                  <p>
-                    Exploring LNURL and finding use cases, is really helping
-                    inform lightning protocol development, rather than the
-                    protocol dictating how lightning-network should be engaged
-                    with.

+        <b>WARNING: LNURL must be used over https or TOR</b><br />
+        LNURL is a range of lightning-network standards that allow us to use
+        lightning-network differently. An LNURL-pay is a link that wallets use
+        to fetch an invoice from a server on-demand. The link or QR code is
+        fixed, but each time it is read by a compatible wallet a new QR code is
+        issued by the service. It can be used to activate machines without them
+        having to maintain an electronic screen to generate and show invoices
+        locally, or to sell any predefined good or service automatically.
+      </p>
+      <p>
+        Exploring LNURL and finding use cases, is really helping inform
+        lightning protocol development, rather than the protocol dictating how
+        lightning-network should be engaged with.

-# Terms and Conditions for LNbits Extension
-
-## 1. Acceptance of Terms
-
-By installing and using the LNbits extension ("Extension"), you agree to be bound by these terms and conditions ("Terms"). If you do not agree to these Terms, do not use the Extension.
-
-## 2. License
-
-The Extension is free and open-source software, released under [specify the FOSS license here, e.g., GPL-3.0, MIT, etc.]. You are permitted to use, copy, modify, and distribute the Extension under the terms of that license.
-
-## 3. No Warranty
-
-The Extension is provided "as is" and with all faults, and the developer expressly disclaims all warranties of any kind, whether express, implied, statutory, or otherwise, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranties arising out of course of dealing or usage of trade. No advice or information, whether oral or written, obtained from the developer or elsewhere will create any warranty not expressly stated in this Terms.
-
-## 4. Limitation of Liability
-
-In no event will the developer be liable to you or any third party for any direct, indirect, incidental, special, consequential, or punitive damages, including lost profit, lost revenue, loss of data, or other damages arising out of or in connection with your use of the Extension, even if the developer has been advised of the possibility of such damages. The foregoing limitation of liability shall apply to the fullest extent permitted by law in the applicable jurisdiction.
-
-## 5. Modification of Terms
-
-The developer reserves the right to modify these Terms at any time. You are advised to review these Terms periodically for any changes. Changes to these Terms are effective when they are posted on the appropriate location within or associated with the Extension.
-
-## 6. General Provisions
-
-If any provision of these Terms is held to be invalid or unenforceable, that provision will be enforced to the maximum extent permissible, and the other provisions of these Terms will remain in full force and effect. These Terms constitute the entire agreement between you and the developer regarding the use of the Extension.
-
-## 7. Contact Information
-
-If you have any questions about these Terms, please contact the developer at [developer's contact information].

-Nostr-transport RPC handlers for the lnurlp (LNURL-pay) extension.
-
-Exposes the same CRUD surface that `views_api.py` exposes via HTTP, but
-encrypted over kind-21000 events through the LNbits nostr transport.
-Mirrors the withdraw extension's `transport_rpcs.py`; both extensions
-hang their handlers off the core dispatcher via their `*_start()` hook.
-
-Auth model (set by the registrations in `__init__.py:lnurlp_start`):
-- *_create / *_get / *_update / *_delete → AUTH_WALLET. The transport
-  resolves the caller's pubkey to a wallet (admin access) before
-  invoking the handler, so we know `auth.wallet.id` and `auth.wallet.user`.
-- *_list → AUTH_ACCOUNT. The caller may list links across all wallets
-  they own, optionally narrowed by `request.wallet_id`.
-
-Ownership: *_get / *_update / *_delete also verify the link's stored
-`wallet` field matches the caller's wallet id — defense in depth, since
-a malicious client could otherwise probe link metadata they don't own.
-
-`resolve_lnurlp_owner` is registered with the core subscription module
-under tag `"lnurlp"` (default link_extra_key `"link"` — that's where
-`views_lnurl.py:86` stamps the link id on settlement). That lets clients
-call `subscribe_payments({tag:"lnurlp", link_id:...})` and stream real-
-time pay events without polling, with ownership enforced server-side.
