Verify a professional email
/people/email-verifierVerify whether an email address is deliverable. Returns a normalized status (valid, accept_all, unknown, invalid) plus provider-agnostic signals (smtp, mx, disposable, webmail, gibberish) — usable as a hygiene step before any outbound send.
Call it over REST
Authenticate with a bearer token against https://api.superagnt.com. Swap the placeholders for your key and parameter values.
curl -s -X POST "https://api.superagnt.com/people/email-verifier" \
-H "Authorization: Bearer <YOUR_AGNTDATA_API_KEY>" \
-H "Content-Type: application/json" \
-d '{ "email": "<string>" }'Copy-paste prompt
Paste this into a coding agent. It connects the superagnt MCP server, finds the tool data_agnt_people_email_verifier, and runs a first call — with the REST fallback if MCP is unavailable.
You are wiring up the superagnt "Lead APIs" API to use this endpoint: Verify a professional email.
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_agnt_people_email_verifier
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.superagnt.com/people/email-verifier
Header: Authorization: Bearer <YOUR_AGNTDATA_API_KEY>
Required parameters:
- email (string, required)
Optional parameters:
- max_cost_cents (number, optional)
3. COST & KEY. This endpoint is metered — pricing varies by request, from $0.002 per call. Only successful calls are charged.

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