Government — entry 003 of 90
Brazil
BrasilAPI is a community-maintained, open-source project — not an official government service — that aggregates and normalizes public Brazilian registries into one keyless REST API. A live `GET /api/cep/v1/{cep}` call confirmed the postal-code lookup works with no key over HTTPS with a wildcard `Access-Control-Allow-Origin` header; the same gateway also fronts CNPJ business-registry lookups, bank/ISPB codes, DDD area codes, national holidays, and IBGE municipality data, each sourced from the relevant official agency. Because it re-serves government data rather than being run by a government body, treat it as a convenience layer, not a primary source for compliance-grade queries.
