AEMO WEMDE DispatchSummary

AEMO's public API catalogue lists 4 operation(s) for this API, gateway-routed under the path prefix /WEM/v1/dispatchSummary. AEMO's own openapi-link export for this API is a shell — it declares paths: {} with zero operations and names an internal host — so the 4 operation(s) in the OpenAPI captured here were harvested from AEMO's developer-portal operations endpoints (https://dev.aemo.com.au/developer/apis/wemde-dispatchsummary-external-v1/operations?api-version=2022-04-01-preview), complete with parameters, headers, response codes and response examples.
