  title: API Evangelist enhancements for Cyware Intel Exchange (CTIX) v3 Open API
  version: 1.0.0
extends: openapi/cyware-intel-exchange-openapi.yml
x-generated: '2026-08-04'
x-method: generated
x-note: >-
  Cyware publishes no OpenAPI document; the spec this overlay extends was assembled by API Evangelist
  from Cyware's own structured per-endpoint reference documents at https://ctixapiv3.cyware.com. This
  overlay records the API Evangelist annotations layered on top of that reconstruction — provenance,
  the authentication contract that the reference states in prose, and the cross-cutting conventions
  captured elsewhere in this repo. It never changes a path, method, parameter or schema.

        note: >-
          OpenAPI cannot express a three-parameter signed request as a single securityScheme, so the
          spec declares the AccessID query parameter as an apiKey scheme and this extension records
          the full contract.

    update:

        Intel Exchange is tenant-hosted. There is no shared SaaS endpoint; the server variable must be
        replaced with the customer's own Intel Exchange host.
