Every request to the ApexVerify API must be authenticated with an API key. This guide walks you through creating your account, generating your first key, and verifying it works — in under 2 minutes.

ApexVerify uses a custom HTTP header for authentication: X-Api-Key: YOUR_API_KEY. Include this header on every API request. Requests without a valid key return 401 Unauthorized.


Steps

1

Create your account

Go to app.apexverify.com and sign up for a free account through your preferred provider.

Sign up for an ApexVerify account

2

Open the Dashboard

Log in at app.apexverify.com. The dashboard is your control center for API keys, uploads, credit usage, and settings.

3

Generate your API key

Navigate to API Access and click ADD API KEY.

Rename the key (e.g. production, dev-local, or ci-pipeline) to describe it for later easy analytics. Copy the key immediately and start use it.

4

Test your key

Run the following request to confirm the key is working. It fetches your current credit balance:

$curl -X GET https://api.apexverify.com/v1/account/credits \
> -H "X-Api-Key: YOUR_API_KEY"

A successful response looks like this:

1{
2 "email_credit": 1000.0,
3 "phone_credit": 500.0
4}

If you receive 401 Unauthorized, double-check that the key was copied correctly and the header name is exactly X-Api-Key.

You can also try it from documentation like above on ApexVerify API Web UI


Never expose your API key in client-side code, public repositories, or unsecured environments. Treat it like a password. If a key is compromised, revoke it immediately from the Dashboard and generate a replacement.

See Creating Additional API Keys for key rotation best practices.
