# Catalogue of every official source — keyless

**GET /api/open/central-banks**

Every central bank and tax authority the API serves, with the date of its latest published table, its age in days, a stale flag and its publication cadence. No API key. Use it to discover source codes for the other central-bank endpoints and to check freshness before citing a rate.
