Taxrates.io / TaxRate.io provides tax-rate lookup and monitoring data, including U.S. sales tax and international VAT/GST rates. It offers online lookup tools and APIs for retrieving tax rates by location and related tax data.
taxrates.io exposes one documented REST API at `https://api.taxrates.io/api` with an OpenAPI spec and a separate TaxRate.io REST API at `https://www.taxrate.io/api/v1`; both require a user-issued API key.
