Thank you for your query.
If you are trying to fetch the screening results of an already screened case by passing the entity name, I would like to inform you it is currently not possible via World-Check One API. You can only do that using the World-Check One UI.
If you are trying to fetch the results as soon as you pass the name for screening, you can do that using the API call - 'SEQ-screen-sync-individual: Perform Synchronous Screening: Individual', which saves, screens and fetches the screening results using a single API call. More details around this is availble in the following link under 'World-Check One API sync Screening Steps'-
Hope this answers your query.
