The Routing Bank Number Checker API is a tool that allows developers to validate bank routing numbers. This API checks the validity of the routing numbers entered, ensuring that they are correct and belong to a legitimate bank. It can be integrated into banking or financial software applications to prevent fraud and errors in transactions.

Check up to fifty addresses per call, or extract every link of a page and validate each one: status code, redirect chain, response time and a working or broken summary. Smart checking with automatic fallback.
