This endpoint allows you to retrieve a specific bank by providing the bank ID. You can include related data like scores and country information in the response.

This tool queries a directory of banking information and returns data about a specific bank based on its ID. It performs no write, delete, execute, or financial operations. The data retrieved (bank ratings, scores, country information) is informational only and carries no blast radius if misused by an AI agent—at worst, an agent retrieves incorrect or irrelevant banking information.
From the tool's definition Tool name 'bank_getById' and description 'retrieve a specific bank by providing the bank ID' indicate a pure read operation. The verb 'retrieve' and phrase 'include related data...in the response' confirm no data modification or side effects.
