GET /v1/s3/buckets/{bucket}/objects

Address	`https://api.hanzo.ai/v1/s3/buckets/{bucket}/objects`
Method	`GET`
Operation	`get_s3_buckets_by_bucket_objects`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Lists one folder level of a bucket.

Folder-style by default: sub-prefixes come back as directory entries, which is the file-manager view. ?recursive=true lists every key flat under the prefix instead. Keys are RELATIVE to ?prefix=, and the listing is bounded so a huge bucket cannot exhaust memory — Total is what came back, not what the bucket holds.

Billed per call: the balance is checked BEFORE anything is touched, so an unfunded org is refused with nothing read, and the debit lands only once the listing has succeeded.

MCP reaches s3 through the s3 tool, which names its 6 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_s3_buckets"
         }
       }
     }'
