## Request

```json
{"email": "user@example.com"}
```

## Response

```json
{
  "success": true,
  "code": 200,
  "message": "Email validation complete",
  "data": {
    "email": "user@example.com",
    "valid": true,
    "syntax_valid": true,
    "mx_valid": true,
    "disposable": false,
    "domain": "example.com",
    "normalized": "user@example.com",
    "reason": null
  },
  "credits_used": 1,
  "remaining_credits": 99
}
```

**Key fields:**
- `valid`: `true` only when both `syntax_valid` AND `mx_valid` are true
- `disposable`: `true` if the domain is a known throwaway email service
- `reason`: explanation when validation fails (null on success)
- `normalized`: canonical lowercase form of the email

## Error Codes

| Code | Meaning |
|------|---------|
| 400 | Invalid request |
| 401 | Missing or invalid API key |
| 402 | Insufficient credits |

**Cost:** 1 credit per request

## Usage Pattern

1. Use `$APIPICK_API_KEY` env var as the `x-api-key` header value; if not set, ask the user for their apipick API key
2. Make the POST request with the email address
3. Report the `valid` status and flag if `disposable` is true
4. Show `reason` when validation fails
