Map the paid agent API market in one prompt

Before building on paid APIs, it helps to know what's out there. One call lists every category Hagglyai compares, how many paid endpoints each has and the cheapest price.

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

  • Each category lists its paid endpoints and the cheapest price per unit.
  • The sub-category ids (platforms and tasks) narrow a later comparison, e.g. Instagram comments or YouTube transcripts.
  • Use a category id with compare_category or most_popular for the detail.
