Economia.Awesome vs VATComply.com

AwesomeAPI's currency service is a Brazil-centric quote engine spanning 150+ pairs, from majors to BRL tourism rates, PTAX central-bank fixings, and a handful of crypto pairs, with distinct endpoints for the latest quote, minute-by-minute intraday sequences, and up to 360 days of historical closes filterable by exact date range. No credentials are required for basic use, and registering for a free API key raises the request ceiling and removes a short response-caching delay. Documentation is Portuguese-only.

VATcomply bundles several EU compliance primitives behind one free, keyless API: VIES-backed VAT number validation, current VAT rates for all 27 EU member states, daily ECB foreign-exchange reference rates with history back to January 1999, IP-based geolocation, and IBAN validation. Rather than gating access behind an API key, it simply rate-limits anonymous callers, and it ships both narrative documentation on its homepage and a full interactive OpenAPI reference at a separate endpoint.
