Brazil Receita WS
ReceitaWS looks up registered Brazilian companies by CNPJ (tax ID) and returns name, address, share capital, and partner (QSA) data sourced from the Receita Federal. The free tier is keyless but capped at 3 requests/minute and omits Simples Nacional and state (Estadual) registration status; a paid token starting around R$149/month lifts the rate limit and unlocks the fuller record.
ReceitaWS is a keyless CNPJ (Brazilian company tax ID) lookup service, mirroring registration data from the Receita Federal. A live GET this run against /cnpj/27865757000102 (Globo's CNPJ, a stable public company) returned a genuine 200, 5,093 B JSON record at content-type: application/json; charset=utf-8, with no access-control-allow-origin header on any probe — confirming the stored cors: no; browser code needs a server-side proxy. The free tier is capped at 3 requests/minute (x-ratelimit-limit: 3), live-confirmed this run, and omits Simples Nacional/Estadual registration status; a paid token via https://developers.receitaws.com.br/ lifts the limit and adds those fields.
