User Post Rank In Subreddit

You are wiring up the agntdata "Reddit" API to use this endpoint: User Post Rank In Subreddit.

1. CONNECT over MCP (preferred). Add the superagnt MCP server, then let the client
   run OAuth on first tool call — no token to paste:
     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_reddit_user_post_rank_in_subreddit
   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.agntdata.dev/getUserPostRankInSubreddit
     Header: Authorization: Bearer <YOUR_AGNTDATA_API_KEY>
   Required parameters:
    - sort (string, required) — Sort order: hot, new, rising, top
    - username (string, required) — Reddit username (e.g. spez)
    - subreddit (string, required) — Name of the subreddit (e.g. reddit)
   Optional parameters:
    - time (string, optional) — Required when sort is top: hour, day, week, month, year, all
    - max_pages (number, optional) — Maximum pages to scan (1-10, default: 4)

3. COST & KEY. This endpoint is priced per call in credits, and each successful response reports its own cost in its meta.costCents field. Only successful calls are charged.
   Get an agntdata API key at https://app.agntdata.dev.

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