+Title: Add verbose CLI flag (-v) with redacted HTTP logging
+
+Short description:
+- Add a global `-v/--verbose` CLI flag to enable redacted HTTP request/response logging to help debug interactions with the Databus and Vault.
+
+What changed:
+- Add global `-v/--verbose` option to `databusclient` CLI and propagate it to API calls.
+- Implement redacted HTTP logging helper (redacts `Authorization` and `X-API-KEY` headers).
+- Instrument `download` and Vault token exchange flows to print HTTP request/response details when `-v` is enabled.
+- Add unit tests ensuring verbose logs are printed and sensitive tokens are redacted.
+- Update `README.md` and add a `CHANGELOG.md` entry.
+
+Why:
+- Provides safe, actionable debugging output for issues involving HTTP communication and auth problems without exposing secrets.
+
+Security note:
+- Authorization and API-key headers are redacted in verbose output. Avoid enabling verbose output in public CI logs.
+
+Closes #27
