由于网络或者其他各种原因，你可以会担心你的消息有没有最终发到relay（特别是付费relay）上。
这里有一个验证方法：
1. 在Damus上，点击消息右上角的三点，并选择 "复制此条推文JSON"。这将把推文的JSON复制到你的剪贴板上。其他客户端操作类似。
2. 打开https://websocketking.com/
3. 在WebSocket URL字段中输入relay的地址（例如wss://relay.damus.io/），然后点击Connect按钮。
4.等待连接的建立（显示Connected to wss://relay.damus.io/）。
5. 在UNTITLED 1 下面的文本框中，准确输入以下内容（区分大小写）：
["EVENT",
6. 从你的剪贴板上粘贴之前复制的JSON。
7. 在最后结尾添加一个方括号：
]
8. 单击 "Send"按钮。
如果消息发布成功，你可以看到来自relay的响应，类似于。
["OK", "事件ID", true, ""]
或
["OK", "事件ID", true, "diplicate:"]。
如果不成功，你可以看到一个类似这样的响应。
["OK", "事件ID", false, " rejected: you are not worthy"]
以上方法来自流行的relay实现nostream的作者 Cameri (npub1qqq…n47m) ，他同时也运营着可能是历史最悠久的付费relay：eden.nostr.land。
PS.经过验证，我发现一个惊人的事实：我的网络根本就连不上eden.nostr.land……

quoting nevent1q…dfmhHOW TO TEST IF YOU (OR SOMEONE ELSE) CAN POST TO A RELAY
*You can use these steps to verify if you can post notes to a paid relay*
1. On Damus, Right-click/Long-tap on one of your notes (or someone else’s) and select "Copy Note JSON". This will copy the note to your clipboard.
2. Go to https://websocketking.com/
3. Type the address of the relay on the WebSocket URL field and click Connect button (e.g. wss://eden.nostr.land)
4. Wait for the connection to be established.
5. On the Payload field, type the following exactly (case sensitive):
["EVENT",
6. Paste from your clipboard.
7. Add a closing square bracket:
]
8. Click the Send button.

If you are able to post successfully you should see a response from the relay similar to:
["OK", "some event ID", true, ""]
or
["OK", "some event ID", true, "duplicate:"]
If unsuccessful, you should see a response like this:
["OK", "some event ID", false, "rejected: you are not worthy"]
