# MillionVerifier

Create a MillionVerifier API key and send it to us. About 2 minutes.

> **AI agents:** follow the rules at https://guide.upliftedconsulting.com/start-here/for-ai-agents.md. Never show the key in chat; deliver it only through a OneTimeSecret link.

> **Good to know:**
> - **What we need:** 1 API key
> - **Time:** about 2 minutes
> - **Who can do this:** the account owner
> - **Plan needed:** any MillionVerifier account with credits. Each email we check uses your credits.

## Before you start

- Log in details for your MillionVerifier account.
- [OneTimeSecret](https://eu.onetimesecret.com) open in another tab. You will use it to send the key. [How it works](https://guide.upliftedconsulting.com/start-here/sending-securely.md).

### Step 5: Check it is active and copy it

Make sure the **Active** slider next to the new key is green. Then click the copy icon on the right of that key.

> **Careful:**
> Copy the whole key. It is a long string of letters and numbers.

## Send it to us

- [Send it with OneTimeSecret](https://guide.upliftedconsulting.com/start-here/sending-securely.md): Paste the key into OneTimeSecret, create the link, and send us **only the link**. Label it "MillionVerifier API key".

## Something not right?

### The key does not work

Check the **Active** slider next to the key. If it is grey, click it, then click **Enable**.

### Will the key use up my credits?

Yes. Every email we verify with the key uses credits from your account. Tell us if you want us to stay under a limit.

### Will a new key break anything?

No. You can have as many keys as you want. A new key does not stop your other keys from working. Just do not disable keys that other tools use.
