How to fill in address data through the CNPJ? [closed]

You can try searching for the CNPJ in the federal income website .

Process

• Use some curl or soap service via server to simulate a client and retrieve information.
• Use an HTML parser to retrieve the desired data.

Problems

• It has captcha, but for my tests only the need to fill once, after that just consult normally.
• It has a session timer
for the captcha of + or - 5min.

I do not know of a framework that can bring this "tray" information to you, I do not think it exists.

A database service will be required, in which there will be at least cnpj (primary key), address, zip, etc.

For development, you can use mySql with xampp or wampServer. =)

There are some companies that make this available:

But a charge is made per query.
