  base: https://api.vulncheck.com/v3
  note: >-
    The major version is carried in the path. A v4 advisory surface exists and ships in the MCP
    server as the v4_* tool family; the 2026-09-02 release notes state "v4 advisory support is
    now complete". No public REST base URL or OpenAPI for v4 is published, and v3 remains the
    documented API. Callers therefore cannot yet plan a v3-to-v4 migration from published
    material.

  note: >-
    No deprecation or sunset policy is published, and the OpenAPI marks no operation
    `deprecated: true`. Nothing in the 521-operation contract, the docs or the changelog states
    a notice period or an end-of-life process for an index or an endpoint. Given that the
    product is 490+ named indices which the changelog shows being added continuously, the
    absence of a stated retirement policy is a real gap for anyone building on a specific index.

    The 2026-07-22 release notes reference "Production API Service Level Objectives (SLOs)"
    being refined internally, but no SLO or SLA figure is published to customers.
