#26207
REST calls via TL script to external APIs according to OpenAPI specification
It should be possible to define TL-Script functions that call external APIs according to the OpenAPI specification (https://www.openapis.org/) and return the result for further processing.
This issue is related to #25644, where new TL-Script functions are to be defined that, in turn, are defined via TL-Script and executed locally.
