Available tools · 22

Each tool is independent — your agent loads only what it needs to reduce context and response time.

READget_oauth_token

Mint or return a cached OAuth2 client_credentials bearer token for the Itaú Developer Portal. Exposed so agents can inspect token freshness; normal tool calls obtain tokens implicitly.

WRITEsend_pix

Initiate an outbound Pix payment from the merchant's Itaú account. Amount in BRL major units (e.g. '10.50').

WRITEcreate_pix_qr

Create a dynamic Pix charge with QR code (cob). Returns the txid, copy-paste EMV payload, and location URL.

READget_pix

Retrieve a Pix transaction by its BCB endToEndId (E<ispb><yyyymmddhhmm><sequence>).

READresolve_dict_key

Resolve a DICT key (CPF, CNPJ, email, phone, EVP) to the owner's account data before sending a Pix. Subject to BCB rate limits per consenting payer.

DELETErefund_pix

Refund (devolução) a previously received Pix. Must reference the original endToEndId and a merchant-side refund id.

WRITEcreate_boleto

Issue a boleto via Itaú Cobrança. Returns nosso_numero, linha_digitável, barcode, and PDF URL.

READget_boleto

Retrieve a boleto by its Itaú identifier (id or nosso_numero).

Frequently asked questions

All credentials are encrypted at rest in an isolated vault scoped per organization. OAuth2 tokens are automatically refreshed before expiry. Your agent code never sees raw secrets — it receives scoped, short-lived session tokens.
