How this service works
List objects
Output
An XML document (ListBucketResult) containing the bucket name, prefix used, whether results are truncated, the marker position, max keys limit, and a list of matching object keys stored in the bucket.
Example use cases
Example prompt
“Show me all the files stored in my tempo.xyz R2 bucket under the prefix 0x9cc42f3d9245b867acccd630b43f906c1665b176/ — I want to see the full object listing.”
Technical details
Endpoint
GEThttps://storage.mpp.tempo.xyz/?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover what objects exist in an S3/R2-compatible bucket before downloading, deleting, or processing them. Prefer this over direct object access when you don't know exact object keys in advance or need to enumerate files under a namespace/prefix.
Side effects
- Empty result set if no objects exist under the given prefix
- Truncated results if more than 1000 objects exist — requires pagination via marker
- Authentication/authorization error if credentials are missing or invalid
- Malformed XML response if the service is degraded
- Timeout if the bucket is very large
