Implement cnpj information from brasiliapi

[aniltonveiga]

The Brasilapi project (https://brasilapi.com.br/) maintains open and free information about CNPJ such as: opening date, registration status, and partners.

For BrasiliApp, this information is important, as it is known that many politicians hire front companies, or companies belonging to relatives, to perform services.

Como

When clicking on the 'Verificar' button, make a request to: https://brasilapi.com.br/api/cnpj/v1/{CNPJ} Entering the company's CNPJ without dots or dashes.

In the response of this request will require the use of the following properties:

• razao_social
• nome_fantasia
• capital_social
• data_inicio_atividade
• descricao_situacao_cadastral
• qsa (Sócios da empresa)
