How this service works
Brazilian company & public-procurement data for due-diligence, KYB & B2B agents: company profiles by CNPJ, regulatory risk & compliance screening (federal debarment, anti-corruption, leniency & forced-labor register — CEIS, CNEP, 'Lista Suja'), mass search & segmentation across ~28M active companies, and public tenders / licitações (PNCP).
Output
A JSON object containing the parsed NF-e key components: the Brazilian state (code, name, abbreviation), invoice model (code and description), series, full access key, check digit, issuer CNPJ (raw and formatted), numeric code, emission type, invoice number, emission year-month, and a human-readable document type description.
Example use cases
Supplier invoice verification for accounts payable
“I received this NF-e key from a supplier and need to confirm the issuing CNPJ, invoice number, and emission month before we process payment: 35250611444777000161550010000123451000000011 — can you decode it?”
Extracting issuer CNPJ for KYB screening
“Pull the issuer's CNPJ out of this NF-e access key so I can run a compliance check on them: 35250611444777000161550010000123451000000011.”
Auditing NF-e metadata for tax reconciliation
“I need to reconcile this NF-e against our ERP records — decode the access key 35250611444777000161550010000123451000000011 and give me the state code, series, invoice number, and emission date.”
Technical details
Endpoint
GEThttps://brdata.thomenz.me/nfe/%7Bchave%7DWhen to prefer
Use this endpoint when you have a raw Brazilian NF-e access key (chave de acesso) and need to extract structured metadata from it — particularly the issuer CNPJ, state, invoice number, and emission date — for compliance, accounts payable automation, or KYB workflows. It is specifically designed for the Brazilian electronic invoice ecosystem and returns a ready-to-use English-schema JSON, making it ideal for agents that need to bridge Brazilian fiscal data into international workflows.
Side effects
- Invalid or malformed 44-digit access key returns an error
- Non-NF-e document type keys (e.g. NFS-e, CT-e) may not parse correctly
- Check digit mismatch may result in validation error
- Missing or empty chave parameter returns a bad request error
