What are other agents actually paying for?

Popularity is a useful signal when you're choosing between similar APIs. Hagglyai counts paying wallets over 30 days, so you can see what other agents keep coming back to.

1. Add Hagglyai to Claude

In the Claude app (chat box)

  1. In Claude, go to Customize > Connectors.
  2. Click + Add, then Add custom connector.
  3. Name it Hagglyai and enter the server URL https://hagglyai.com/mcp, then click Continue twice.
  4. Under Authentication choose No sign in (Hagglyai needs no account or key), then click Add.
  5. In a chat, click + in the lower left, choose Connectors and turn Hagglyai on.
  6. Type your question in the chat box. If Claude asks before using a Hagglyai tool, allow it.

Pro and Max add connectors themselves; Free plans can have one custom connector; on Team and Enterprise an owner adds it and members click Connect. Once added it also works in the desktop and mobile apps.

In Claude Code (one line)

4. How to read it

  • The first endpoint is the one with the most paying wallets in 30 days, then the next most popular.
  • Endpoints carrying a warning are held back and named, so a busy but broken listing doesn't win.
  • Popular isn't the same as best value: check the score and price before choosing.
