What can your agent do in BrasilAPI?

Any of BrasilAPI's 20 actions, including Get address by CEP, Get area code info, Get bank by code and Get book info by ISBN. Your agent maps the data both ways and tests every scenario before it ships.

Which apps can BrasilAPI connect to?

Any app in the catalog; the list on this page pairs BrasilAPI with each of them. If the other app is missing, point your agent at its API documentation and it builds the connector.

What happens when something fails?

Is there a free plan?
