Zero Footprint Screening - V2


LSEG World-Check One API Zero Footprint Screening (ZFS) API enables customers to screen entities without the need to permanently store data on LSEG’s platform. No case or matched data is stored, thus offering an ideal lightweight solution for on-demand screening.

The ZFS API provides a subset of the capabilities of Case Management and Audit, namely:

  • Screen names, with or without secondary identifiers

  • Provide results of the screening process

  • Provide the detailed World-Check information for matched individuals, organizations, or vessels

  • Allow the use of Internal Watchlists


Since there are no saved cases and matches when using the Zero-Footprint Screening API, integrations should be using the available API endpoints to perform the necessary operations:

  • Cases are created and screened via the API using a synchronous approach

  • Case details are returned via the API for review and investigation, or local storage

  • Group configuration and other Admin-related functions are done via the WC1 Desktop

ZFS API clients may also do ad-hoc screening via the WC1 Desktop. All provided information and match results will not be stored.

Sample Use Cases
