Datanomik API and developer resources

Datanomik exposes through its API everything the treasury platform collects from banks: accounts, balances, statements, transactions, investments, fees and payments, in Brazil and Uruguay. This page gathers the official entry points to integrate over REST, to automate workflows, and to connect AI agents to the Datanomik MCP server.
