bunq tooling

The official bunq SDKs make authentication and request signing more painful than they need to be, so I wrote a TypeScript client that hides the signature handling behind a plain interface.

On top of it sit a custom n8n node for wiring bunq into automation flows, and a set of experiments in categorising and querying my own transactions. The client is a personal proof of concept and has not been audited — it is not meant for production use.
