# Verify an email address

Checks whether an email address is deliverable and returns its status (valid, invalid, accept_all, webmail, disposable or unknown), a score and the checks behind it.

Note: Past 20 seconds it returns `202`: call again with the same email until the result arrives. Read `status`, not the deprecated `result`. Costs half a credit and saves the email to your Hunter leads unless that is turned off.

## Set up

Use the first option your agent supports.

### MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

```json
{ "mcpServers": { "hunter": { "url": "https://mcp.hunter.io/mcp" } } }
```

Call the MCP tool `Email-Verifier`.

Server URL: https://mcp.hunter.io/mcp

### API (official)

- Base URL: https://api.hunter.io/v2
- Endpoint: `GET /email-verifier`
- Auth: send the header `X-API-Key: $HUNTER_API_KEY`
- Get a key: https://hunter.io/api-keys
- Docs: https://hunter.io/api-documentation/v2

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
