  description: >-
    Horizon is a prepaid-credits REST API for LinkedIn/company enrichment, email
    finding and verification, job search, and web search. Every request
    authenticates with an `Authorization: Bearer <key>` header and, on a billed
    endpoint, debits a fixed number of credits from your prepaid balance (see
    each endpoint's description for its exact cost). Check your balance any time
    with GET /v1/usage.
