  description: >-
    Apollo authenticates every request with an API key passed in the
    `x-api-key` header (for example `x-api-key: YOUR_API_KEY`). Keys are
    generated in Apollo's developer settings. Some endpoints - such as People
    Search and listing account users - require a key that has been marked as a
    master key. API access is gated by plan tier: programmatic access begins on
    the Professional plan.
