  title: API Evangelist enhancements for the ACMA Spectrum Licensing API
  version: 1.0.0
extends: openapi/acma-spectrum-licensing-openapi.yml
x-generated: '2026-07-25'
x-method: generated
x-note: >-
  ACMA publishes no OpenAPI. The document this overlay extends is itself an API Evangelist
  reconstruction from ACMA's published guide, the live WSDL and live-probed responses. This
  overlay records the API Evangelist annotations layered on top of that reconstruction — the
  rating, the artifact cross-links, the agent-facing warnings and the licence constraint —
  so they stay separable from the reconstructed contract.

      attribution_required: 'Based on Australian Communications and Media Authority information'
      prohibited_uses:
      - Unsolicited commercial electronic messages (Spam Act 2003)

      note: >-
        This is the real access control on an otherwise anonymous API. Any agent or product
        redistributing these records inherits these constraints.

  update:
    x-agent-warnings:
    - >-
      Results are silently truncated at 2,000 records per query. Always read TOTAL_RESULT and
      page with offset before treating a result set as complete.
    - >-
      An empty result is HTTP 200 with an empty array, not a 404.
    - >-
      Errors are HTML fault pages with no machine-readable body — there is no problem+json,
      no error code and no correlation id.
    - >-
      Frequency units differ by operation: Hz on registration and assignment rows, MHz on the
      400 MHz register.
    - >-
      Request dates on AssignmentRange are DD-MM-YYYY; response dates are ISO local datetimes.
    - >-
      Identifier types are inconsistent — CLIENT_NO is a JSON number on some operations and a
      string on others. Treat all identifiers as strings.
    - >-
      The register records LICENCES, not transmissions. Absence from the register is not proof
      a band is clear; class-licensed and defence spectrum are not in this dataset.

        ACMA's published answer for whole-dataset use is a daily complete extract, not paging
        this API. The 2,000-record cap exists to enforce that.

    x-withdrawn-operations:
      note: >-
        Documented in ACMA's guide with the single word "Deprecated" and absent from the live
        WSDL. Not modelled as paths in the reconstructed OpenAPI because no URI template was
        ever published for them.
