Enrich a person

You are wiring up the agntdata "Lead APIs" API to use this endpoint: Enrich a person.

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_agnt_people_enrich
   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/people/enrich
     Header: Authorization: Bearer <YOUR_AGNTDATA_API_KEY>
   Required parameters:
    - identifiers (object, required) — Unique handles used to resolve a person upstream. Provide AT LEAST ONE of `email` or `linkedin_url`. Name + company are NOT accepted here — for that flow, call `/people/email-finder` first to obtain an email.
   Optional parameters:
    - fields (array, optional)
    - max_cost_cents (number, optional)

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

  "description": "Enrich a person with normalized fields (email, mobile, job title, company, LinkedIn URL, location, …). REQUIRES a `identifiers` object containing ONLY `email` and/or `linkedin_url` — these are the unique handles we use to resolve the person upstream. `first_name`, `last_name`, `domain`, `company`, etc. are NOT accepted here and will return a VALIDATION_ERROR. If you only have a name + company, call `/people/email-finder` first to obtain an email, then pass that email here. Optional `fields[]` narrows the waterfall to only fetch the fields you care about. agntdata runs a field-aware waterfall: it stops once all requested fields are filled or your `max_cost_cents` budget is exhausted.",
