  title: API Evangelist enrichment overlay — ValueSERP News API
  version: 1.0.0
  x-description: Non-destructive enrichment applied by the API Evangelist pipeline on top of openapi/valueserp-news-api-openapi.yml.
    It adds provenance, agent-governance classification, billing and retry semantics, and cross-links
    to the runtime-semantics artifacts in this repository. It changes no path, parameter, schema or response
    defined by the underlying document.

      note: Traject Data publishes no OpenAPI for ValueSERP. api.valueserp.com returns HTTP 404 for /openapi.json,
        /openapi.yaml, /swagger.json, /api-docs and /docs; docs.trajectdata.com is an Archbee SPA that
        answers 200 with an HTML shell. This document was derived from the published reference, not harvested.
