Get Profile's Posts

You are wiring up the agntdata "LinkedIn" API to use this endpoint: Get Profile's Posts.

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_linkedin_get_profile_s_posts
   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/get-profile-posts
     Header: Authorization: Bearer <YOUR_AGNTDATA_API_KEY>
   Required parameters:
    - username (string, required)
   Optional parameters:
    - start (string, optional) — use this param to get posts in next results page: 0 for page 1, 50 for page 2 100 for page 3, etc.
    - postedAt (string, optional) — It is not an official filter. It filters posts after fetching them from LinkedIn and returns posts that are newer than the given date. Example value: 2024-01-01 00:00
    - paginationToken (string, optional) — It is required when fetching the next results page. The token from the previous call must be used.

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.

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