HTTP QUERY: the immediate future of API queries

A new way to carry complex queries without turning the URL into a puzzle or presenting a read operation as if it were a write.

A small demo because the ecosystem is only getting started

To explore this immediate future, the Demo_http_query project was created with PowerBuilder 2025 R2 and a local ASP.NET Core API. During preparation of the demo, we did not identify a widely documented public API exposing a QUERY endpoint that would be suitable for a reproducible demonstration. A small, controlled API was therefore built around an in-memory product catalog.

The window builds one query and sends it as GET, POST, or QUERY. It also uses OPTIONS to discover supported methods and the Accept-Query header to advertise the accepted format. The response is displayed as a navigable JSON tree, making the difference between methods visible without hiding the result behind a console.
