atlasref
Reference data for countries, regions and public holidays — versioned, sourced and API-first.
atlasref publishes reference data with provenance: every record names its source, licence and verification status.
- Official sources first, with the source and licence stated on every record.
- Snapshots and change feeds, so you can follow what changed and when.
- One API, two products: country data and public holidays.
