Find a domain's organic competitors

You are wiring up the agntdata "SEO" API to use this endpoint: Find a domain's organic competitors.

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_seo_competitors
   Call agnt_tools_search or agnt_tools_list_enabled to confirm it is available.

2. REST fallback (if you are not using MCP):
     POST https://api.agntdata.dev/competitors
     Header: Authorization: Bearer <YOUR_AGNTDATA_API_KEY>
   Required parameters:
    - target (string, required) — Domain to find competitors for, no protocol.
   Optional parameters:
    - location_code (integer, optional) — Geo target as a location code. Default 2840 (United States).
    - language_code (string, optional) — Two-letter language code. Default 'en'.
    - limit (integer, optional) — Max competitor domains to return. Default 100.
    - filters (array, optional) — Optional filter expression as [field, operator, value] triples. Recipe: [["intersections",">",50]] keeps only domains sharing 50+ keywords with the target.
    - order_by (array, optional) — Sort rules, e.g. ["intersections,desc"].

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_seo_competitors), run one minimal call with just the required parameters,
   and report back the shape of the JSON response (top-level fields).

Note: the first row is the target itself, and generic high-overlap mega-domains (youtube.com, linkedin.com) dominate the default output — skip the self row and filter, e.g. filters: [[\"intersections\",\">\",50]], or sort with order_by: [\"metrics.organic.count,desc\"] and judge overlap yourself.
