Relates to this document: https://bitsomx.atlassian.net/wiki/spaces/Rails/pages/3263234056/Pix+third+party+withdrawals

• In order to perform a withdrawal to a PIX key, first we have to get the bank account details related to that PIX key; this is done though BR banking integration and goes to the central bank;
• Bank account details contain sensitive personal information;
• We (as a company) are subject to throttling/temporary blocks as this mechanism may be abused to obtain sensitive personal information;
• This throttling/temporary block that may be applied on us is based on token bucket concept;
• We are going to temporarily block our users individually when they take us to scenarios where we spend tokens; this is what this new error is about

Just one question: Is this going to be used by the frontend or would anyone interacting with the site through the API could get that error?

Front ends are using our error messages (coming from message bundles in withdrawal-* services) as pass-through, i.e. they are not using the error code to map to an error message. This API is accessible through public API (withdrawals) though as far as I understand, and they may suffer this error too.
