## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability brdata-nf-e-access-key-parser-5f3d00ba
```

Example prompt: Parse this Brazilian NF-e access key for me and tell me the issuer's CNPJ, the state it was issued in, the invoice number, and the emission date: 35250611444777000161550010000123451000000011.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
