Verify Email

Use case

Check a specific address you already have, such as an email typed into a signup or booking form, before you rely on it. The request returns the verdict directly, typically in under a second.

/verify-email checks the exact address you send. To discover an address for a person, use Find Email.

Endpoint

POST https://api.sixtyfour.ai/verify-email

Errors

For error responses (400, 403, 422, 429, 503, etc.), see Handling Errors. Each organization can make 120 requests a minute. Past that, the API returns 429 with a Retry-After header.

Request

Field	Type	Description
`email`	string	The address to check. Required.

Response

Field	Type	Description
`email`	string	The address that was checked.
`status`	string	`OK`, `RISKY`, `INVALID`, or `UNKNOWN`. See Statuses.
`score`	integer or null	0 to 100. Higher is more likely to be delivered.

Statuses

OK and RISKY mean the same as in Find Email. Here UNKNOWN always means the check was inconclusive; Find Email can also return UNKNOWN as a placeholder for an address you supplied and it did not check. Verify Email returns INVALID for an invalid address. Find Email leaves invalid addresses it discovers out, and returns NOT_FOUND when it has no address.

Status	Meaning
`OK`	The mail server accepted the address.
`RISKY`	The address can receive mail but delivery is uncertain. Most often the company’s domain accepts every address, so the mailbox itself cannot be confirmed.
`INVALID`	The address or its domain does not exist, or the server rejected it.
`UNKNOWN`	The mail server did not give a clear answer.

Usage

curl -X POST "https://api.sixtyfour.ai/verify-email" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"email": "jane@gmial.com"}'

import requests

response = requests.post(
    "https://api.sixtyfour.ai/verify-email",
    headers={
        "x-api-key": "YOUR_API_KEY",
        "Content-Type": "application/json"
    },
    json={"email": "jane@gmial.com"}
)

response.raise_for_status()
result = response.json()

const response = await fetch("https://api.sixtyfour.ai/verify-email", {
  method: "POST",
  headers: {
    "x-api-key": "YOUR_API_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({ email: "jane@gmial.com" })
});

if (!response.ok) {
  throw new Error(`Verification failed (${response.status}): ${await response.text()}`);
}

const result = await response.json();
console.log(result);

Response

{
  "email": "jane@gmial.com",
  "status": "INVALID",
  "score": 0
}
