# CNPJ.ws Project

This project is a byproduct of [**Bitize**](https://www.bitize.com.br/), a procurement management platform focused on finding good suppliers.

[**Bitize**](https://www.bitize.com.br/) is developing a tool for prospecting **Suppliers** and for this, a database with public information of Brazilian companies has been developed and is being enriched with information from various public agencies.

The focus of CNPJ.ws is to provide a fast, updated, and easy-to-use API that returns public data of Brazilian companies made available by the [Access to Information Law](http://www.planalto.gov.br/ccivil_03/_Ato2011-2014/2011/Lei/L12527.htm).

We have a public API because this information should be accessible to everyone.

The challenge now is to obtain data regarding state registrations. We already have data from some states ([see the states here](https://docs.cnpj.ws/modelos-de-dados/inscricoes-estaduais)) but the task is really complicated due to the lack of standardization among the states. We are working hard on this!

We will be posting updates here! See you soon!
