    TESA's B2B treasury infrastructure API. USDC comes in through Circle's CCTP

    (Ethereum and Solana) and is allocated to tokenized Treasuries (USDY and
    BUIDL).

    The API is non-custodial: it never receives a private key or a signed
    transaction.

    It returns unsigned transactions and approval requests, and the signer is
    the

    company or its custodian.


    Resource paths, field names, event names and error codes are in Portuguese
    by

    design. Amounts are USDC decimal strings with two decimal places, dates are
    ISO

    8601 UTC and lists use cursor pagination (`limite` and `apos`). All example

    values are illustrative.
