The short answer: RegSearch Web is the web-based route for reviewing supported MiFID II and EMIR Refit reference data, available ESMA and FCA FIRDS data, identifier- and date-based ToTV/uToTV information and evaluation history.
It is designed for reporting, compliance and data teams that need a practical way to review current and historical regulatory-data questions without turning the public website into an instrument-level lookup service.
What RegSearch Web supports
RegSearch Web brings RegTech DataHub’s regulatory reference data into a web-based review service. It can support day-to-day checks, historical case review and back-reporting investigations.
- Review MiFID II and EMIR Refit reference data.
- Work with available ESMA and FCA reference data, including supported FIRDS coverage.
- Use identifier- and date-based ToTV/uToTV information for supported workflows.
- Review evaluation history for current and historical investigations.
Three ways teams use RegSearch
Day-to-day checks
Review a supported identifier together with the available reference-data and evaluation context for the current case.
Historical case review
Use date-aware information and evaluation history when investigating how an earlier reporting case was assessed.
Back-reporting investigations
Use source-backed reference data, relevant dates and documented limitations when reviewing historical reporting obligations.
RegSearch Web, MiFID API and EMIR API
RegSearch is the web-based review service. The MiFID API and EMIR API are separate subscription services for structured delivery into reporting, reconciliation and downstream data workflows.

Coverage and interpretation
Coverage depends on the product, source, identifier, date and jurisdiction. RegSearch Web provides regulatory reference data, product support and decision support for use within clients’ own regulatory interpretation, control and reporting-decision processes.
This public overview does not return instrument-level results or reproduce RegSearch data, product logic, mappings, schemas or API responses.
