  title: SigRank SignalAF Operators API
  version: 1.0.0
  description: Versioned public API for AI operator benchmark data. Read endpoints are public unless stated otherwise. Errors use RFC 9457 Problem Details. API versioning uses URL path segments (/api/v1, /api/v2, etc.). Breaking changes ship under a new major version. Deprecated operations return a Deprecation header (RFC 8594) and a Sunset header with the retirement date. See the versioning and deprecation policy at /developers#versioning.
