What R2 buckets are on this account?
Short answer: You can list r2 buckets in Cloudflare R2 by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Cloudflare R2 List R2 Buckets action to a workflow, map its 0 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ
Questions about List R2 Buckets.
What does the List R2 Buckets action do in Cloudflare R2?
Returns every R2 bucket in the account with name and creation date. Useful for bucket-inventory workflows and for resolving bucket names at workflow-build time.
What inputs does List R2 Buckets require?
List R2 Buckets has no required inputs. Sensible defaults are applied if you leave fields blank.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Cloudflare R2 returns an error?
The run history shows the failed step with its input and the error message Cloudflare R2 returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.
Does List R2 Buckets support batch operations?
Run List R2 Buckets inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Cloudflare R2's rate limits.
