How this service works
Snapshot of every series, all countries
Output
An array of country objects, each containing a list of data series. Each series includes: the ISO 3166-1 alpha-2 country code, series identifier, current value (numeric for rates/wages, array of date-name pairs for holidays), effective_from date, last_confirmed date, source name and URL, a stale boolean flag, optional unit and notes, optional rate components breakdown, and an optional effective_rate where composite levies stack. Covers all countries and all series in a single response.
Example use cases
Example prompt
“Pull the full usaref snapshot — every government data series for every country — so I can check current VAT rates, minimum wages, and public holiday calendars all at once.”
Technical details
Endpoint
GEThttps://usaref.dev/v1/all?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need all series for all countries in a single call — ideal for bulk lookups, compliance tooling, populating a local cache, or cross-country rate comparisons. Prefer this over per-country or per-series endpoints when you need comprehensive coverage and want to avoid multiple round trips.
Side effects
- Payment required (402): x402 payment of $0.02 USDC was not provided or was invalid
- Service unavailable (503): upstream data pipeline is down
- Timeout: large payload may exceed client timeout on slow connections
- Stale data: series marked stale=true means the value is past its expected update cycle and should be treated with caution
