Open Finance API: how access works and how AI agents use it
Open Finance Brasil is a Brazilian open banking ecosystem regulated by the Central Bank, in which institutions expose standardized APIs for data and payment initiation, always with the customer's consent. Only authorized participants connect directly. Ordinary companies usually go through a regulated aggregator or payment initiator. For iTeam, the path is to integrate that partner's API with the company's credential.
What the Open Finance API offers
Consent
Record and manage the account holder's consent, with a defined scope and term.
Accounts and balances
Account data, balances and limits shared with the customer's authorization.
Transactions and statements
Account movements for reconciliation and cash flow analysis.
Credit cards
Statements, limits and card transactions of the account holder.
Credit operations
Information on contracted loans and financing.
Payment initiation
Starting payments, such as Pix (Brazil's instant payment system), through an authorized initiator, with confirmation from the payer.
How to access the Open Finance API
- For partners and customersDirect access requires being an authorized participant, with ecosystem certificates and a secure connection to the institutions. Companies that are not participants use the authentication of the aggregator or initiator they hire, usually an API key or OAuth.
- All access depends on the account holder's consent, with a term and a scope, so track renewals.
- Financial data is sensitive: follow Brazil's data-protection law (LGPD), banking secrecy and the partner's security policies.
- Payment initiation must have human approval and value limits.
What an iTeam agent does with the Open Finance API
Daily bank reconciliation
With the company's consent, the agent pulls statements from several banks through an aggregator and matches entries with accounts payable and receivable in the ERP.
Cash projection
The agent consolidates balances and movements and sends finance a weekly projection with low-balance alerts.
Credit analysis with consent
In a credit operation, the agent organizes the data the customer shared and prepares the file for the analyst to decide.
Payments with dual approval
The agent assembles the payment batch and sends it for approval. Only then does the initiator trigger the Pix payment.

Questions about the Open Finance API
Is the Open Finance API free?
It depends. Data sharing is regulated, and direct access is for authorized participants. Companies that use aggregators or initiators pay according to their contract with that partner.
Do I need to code to use the Open Finance API with iTeam?
Not necessarily. iTeam's HTTP tool reads the API documentation and learns the endpoints, and the deployment team sets up credentials, permissions and tests with you.
Does my company need Central Bank authorization to use Open Finance?
For direct access, yes, you must be a participant. Most companies use an authorized partner, which delivers the data or initiates payments through its own API.
