## What is ApexVerify?

ApexVerify provides two core verification modes:

#### Batch Verification

Upload a TXT file of emails or phone numbers. Configure targeting parameters, trigger parsing, launch verification, and export results as XLSX or JSON. Ideal for lists of any size.

#### Unit Verification

Submit a single email or phone via `POST /v1/unit` and receive a real-time result in under 5 seconds. Built for live form validation and inline data hygiene.
