AEMO Capacity
The Capacity API is used by facility operators and trading participants to submit and receive data relating to capacity trades and day ahead auction for AEMO’s Capacity Transfer Platform (CTP) and Day-Ahead Auction (DAA) market systems. AEMO's public API catalogue lists 13 operation(s) for this API, gateway-routed under the path prefix /ws/gsh/capacity. 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 13 operation(s) in the OpenAPI captured here were harvested from AEMO's developer-portal operations endpoints (https://dev.aemo.com.au/developer/apis/capacity-v1/operations?api-version=2022-04-01-preview), complete with parameters, headers, response codes and response examples.
