Retrieving reanalyses using the PROXI API

I noticed that MassIVE reanalyses (`RMSV*`) projects don't seem to be supported by the PROXI API. For example, the following returns a 404 error:
```
https://massive.ucsd.edu/ProteoSAFe/proxi/v0.1/datasets/RMSV000000253
```

Is there another API endpoint for reanalyses that I've missed? Thanks!
