Example prompt: I need to add UK VAT to a price of £250 — what's the VAT-inclusive total using the current 2026 standard rate?

## When to prefer this

Use this endpoint when you need accurate, up-to-date 2026 standard VAT/GST rates for major global economies (UK, EU, Australia, Canada, Japan, Singapore, UAE, India, and others) and need to either gross-up (add tax) or net-down (remove tax) a monetary amount. Prefer this over a generic tax API when you specifically need international VAT/GST rather than US sales tax, and when you need verified current-year rates without maintaining your own rate table.

## Known failure modes

- Unsupported country code returns an error — only 16 major economies are supported
- Invalid ISO country code format returns a validation error
