Dados Financeiros Abertos

Infraestrutura open source para consultar dados financeiros públicos do Brasil em Python, REST, CLI e MCP.

CI Versão Python Licença MIT Estado

O que é

O projeto agrega fontes públicas brasileiras em uma camada única e auditável para analistas, desenvolvedores, pesquisadores e agentes:

  • biblioteca Python assíncrona;
  • API REST com Swagger e ReDoc;
  • CLI findata;
  • servidor MCP em /mcp;
  • registro local para resolver CNPJ, ticker e nome.

As fontes principais não exigem chaves de API e os testes unitários não acessam a rede. O slug de distribuição é openfindata; o pacote importável e a CLI continuam sendo findata.

Instalação

pip install openfindata

Para desenvolvimento local:

git clone https://github.com/robertoecf/openfindata.git
cd openfindata
pip install -e '.[dev]'
bash scripts/git/install-hooks.sh

Uso rápido

CLI

findata bcb get selic -n 10
findata bcb ptax
findata cvm search Petrobras
findata b3 quote PETR4
findata registry lookup 33000167000101
findata serve

Python

import asyncio

from findata.registry import lookup
from findata.sources.bcb import sgs


async def main() -> None:
    selic = await sgs.get_series_by_name("selic", n=5)
    print(selic)

    entity = await lookup("PETR4")
    print(entity.entities[0])


asyncio.run(main())

REST e MCP

findata serve
curl 'http://localhost:8000/bcb/series/name/selic?n=5'
curl 'http://localhost:8000/registry/lookup?q=PETR4'
