ZumData’s CNPJ snapshot API

Editorial interest 77/100 Selection signal · not a rating of the site

A Portuguese-language API for querying and monitoring Brazilian company-registry data, with each response identifying its source month and reported coverage.

Landing page captured for the 2026-10-07 issue.

For: Products that need Brazilian company-registry data
Worth noticing: A partially loaded snapshot can return `not_in_snapshot` instead of claiming a company does not exist; the site says these responses are not billed.

Field notes

The site says it fetches the Receita Federal’s monthly files in resumable ranges, streams and converts the ZIP contents, then swaps prepared tables in a single transaction. Its example status output reports coverage separately for company and establishment data, including a case where only one of ten establishment parts is loaded. These are descriptions and examples on the homepage, not independent confirmation of a running service.
