<div class="section-label"><span class="num">04</span> Binary</div>
<div class="section-title">A qualifier for <em>categorical</em> analysis.</div>
Each prediction path — [[API/Prediction Engine/Grid|Grid]], [[API/Prediction Engine/MaxFit|MaxFit]], and [[API/Prediction Engine/PSR|PSR]] — has a binary qualifier. Append <span class="mono">/binary</span> to the path. Request body, headers, and options stay the same.
## How to call it
```http
https://api.csanalytics.io/v2/prediction-engine/grid/binary
https://api.csanalytics.io/v2/prediction-engine/maxfit/binary
https://api.csanalytics.io/v2/prediction-engine/psr/binary
```
The qualifier transforms the prediction for binary / categorical work (probability of success or failure, yes / no) instead of a magnitude on the original outcome scale. That is the hosted counterpart of running with a logistic prediction scale.
> [!note]
> Example: if the model is about a sports outcome, `/binary` converts the forecast into a categorical result (win / lose) that lines up with logit-style analysis.
## Configuration
No extra parameters. Use the same [[API/Prediction Engine/Grid#Quick start|basic]] or [[API/Prediction Engine/Grid#Custom settings|extended]] body you would send to the non-binary path. Then retrieve the job with [[API/Prediction Engine/Results|GET /results]].
