  "whatItIs": "IANA assigns 10010/tcp to rxapi, the Open Object Rexx API daemon. It brokers queues, the macrospace, and registered external functions for ooRexx programs, and the interpreter starts it automatically the first time a script needs it — which is why it appears on machines nobody thinks of as ooRexx hosts. The matching UDP entry is Reserved. Nmap sees the port open on about 0.29% of scanned hosts, unusually high for a niche runtime service.",
