# E-mail Lookup

**Endpoint:** <mark style="color:yellow;">POST</mark> <https://irbis.espysys.com/api/developer/combined_email>

Below is a sample request to perform a lookup using the API:

```
{
  "key": "YOUR_API_KEY",
  "value": "EMAIL_ADDRESS",
  "lookupId": "LOOKUPID_VALUE"
}
```

**Instructions:**

* Replace `YOUR_API_KEY` in the "key" field with your actual API Key.
* For the "value" field, insert the email address you wish to search for. For example: `foxproject@bk.ru`.

Ensure you make the necessary substitutions in the provided fields for accurate and successful search queries.

The  lookupId must be set to what is shown in table API lookups types at [Developer page](https://espyosint.ddns.net/developer) or at [API lookup types](/api-lookup-types.md) page
