How this service works
Compare one government reference series (VAT, policy rate, minimum wage, CPI, corporate tax...) across up to 10 North American countries in one call, each row cited to its official source with effective and last-confirmed dates
Output
A structured JSON array with one row per requested country, each containing the current value for the specified series, the official government source URL it was cited from, the date the value became effective, and the date it was last confirmed — all in a single response.
Example use cases
North America corporate tax comparison
“I need to compare corporate tax rates across the US, Canada, and Mexico — can you pull the current rates with their official sources and effective dates?”
Central bank policy rate dashboard
“What are the central bank policy rates right now for the US, Canada, and Mexico? I need each one cited to the official source.”
Minimum wage research across NAFTA countries
“Can you give me the current minimum wage for the US, Canada, and Mexico in one comparison, with the date each rate took effect?”

Endpoint
GEThttps://usaref.dev/v1/compare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compare a single government economic or fiscal reference series across multiple North American countries simultaneously with full citation metadata. It is superior to making individual per-country calls when you need a side-by-side view. Prefer it over general web search when you need machine-readable, officially cited, structured data rather than scraped or unverified figures.
Side effects
- Invalid series identifier returns an error — only catalog-listed series IDs are accepted
- More than 10 country codes in a single request is rejected
- Non-North-American ISO country codes may return empty or error responses
- Data may lag behind very recent government announcements if not yet confirmed
- Missing required query params (series or countries) returns a validation error
