PSRESTful: A REST/JSON and Protobuf layer over PromoStandards SOAP APIs

Short summary

PSRESTful wraps PromoStandards SOAP/XML APIs in a clean REST/JSON layer with OpenAPI documentation, reducing payload sizes by 35-53%. The platform also supports Protocol Buffers for heavy endpoints (80%+ smaller than XML) and adds query, filter, and sort capabilities absent from the original standard. Open-source .proto schemas are published for generating typed clients across multiple languages.
