Media by hashtag

You are wiring up the superagnt "Instagram" API to use this endpoint: Media by hashtag.

1. CONNECT over MCP (preferred). No token to paste either way.
   On Claude (claude.ai, the desktop app, or Claude Code signed in with a Claude
   account), the server is a connector: give the user this link, they click Add
   and approve:
     https://claude.ai/customize/connectors/yours?modal=add-custom-connector&connectorName=superagnt&connectorUrl=https%3A%2F%2Fmcp.superagnt.com%2Fmcp&open_in_browser=1
   Any other MCP client (or Claude Code signed in with an API key): add the server
   and let the client run the browser sign-in:
     claude mcp add --scope user --transport http superagnt https://mcp.superagnt.com/mcp
     claude mcp login superagnt
   MCP endpoint: https://mcp.superagnt.com/mcp
   After connecting, the tool you want is named exactly:
     data_instagram_media_by_hashtag
   Call agnt_tools_search or agnt_tools_list_enabled to confirm it is available.

2. REST fallback (if you are not using MCP):
     GET https://api.superagnt.com/tag-feeds
     Header: Authorization: Bearer <YOUR_AGNTDATA_API_KEY>
   Required parameters:
    - query (string, required)
   Optional parameters:
    - end_cursor (string, optional)
    - fields (string, optional) — Use the `fields` parameter to reduce bandwidth consumption and minimize response size by returning only the necessary data.

3. COST & KEY. Each successful call costs $0.002 in credits. Only successful calls are charged.
   Get a superagnt API key at https://app.superagnt.com.

4. TEST. Connect the server (or set the key), discover the tool
   (data_instagram_media_by_hashtag), run one minimal call with just the required parameters,
   and report back the shape of the JSON response (top-level fields).
