Delphi V5 Sources and Signals

The legacy V4 API is being phased out. See the V4 to V5 Migration Guide for guidance on migrating existing queries.

V5 Sources

Sources available in V5, and the legacy equivalent each one replaces. Legacy sources may originate from the COVIDcast endpoint (V4) or classic source-specific endpoints (V3). A legacy source not listed here has not migrated and remains legacy-only. The table entries are filled real-time using /epidata/v5/metadata/.
