Patch Changes

  • Add URL query parameter support for filtering (e.g., /members?type=sales_agent)

• 00cd9b8: Extract shared PriceGuidance schema to fix duplicate type generation

  Schema Changes:

  • Create new /schemas/pricing-options/price-guidance.json shared schema
  • Update all 7 pricing option schemas to use $ref instead of inline definitions

  Issue Fixed:

  • Fixes Type definition issues causing mypy errors in v3.0.0 #884 (Issue 1): Duplicate PriceGuidance classes causing mypy arg-type errors
  • When Python types are generated, there will now be a single PriceGuidance class instead of 7 identical copies

  Note: Issue 2 (RootModel wrappers) requires Python library changes to export type aliases for union types.

• d66bf3d: Remove deprecated v3 features: list_property_features task, list_authorized_properties task, adcp-extension.json schema, assets_required format field, and preview_image format field. All removed items have replacements via get_adcp_capabilities and the new assets discovery model.
