  description: >-
    Abstract API authenticates by an API key passed as the `api_key` query
    parameter on the request, e.g.
    https://phonevalidation.abstractapi.com/v1/?api_key=YOUR_API_KEY&phone=+14152007986.
    Each Abstract API product (phone validation, email validation, IP
    geolocation, etc.) issues its own distinct key. Live-confirmed 2026-07-12: a
    missing or invalid key returns HTTP 401 with an "Invalid API key provided"
    error.
