Address	`https://api.hanzo.ai/v1/s3/buckets`
Method	`POST`
Operation	`post_s3_buckets`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Makes a new bucket for the caller's org and answers 201 with it.

The physical name is derived from the caller's validated org, so a tenant can only ever create inside its own namespace and no request field can redirect that. A name already taken in the org is 409.

Billed per call: the balance is checked BEFORE anything is touched, so an unfunded org is refused with nothing created, and the debit lands only once the bucket exists.

Request

1 field, body application/json (required).

Field	In	Type	Required	Description
`name`	body	string	—	Name is the bucket's friendly name, matching ^a-z0-9?$.

Response

Status	Body	Meaning
`201`	s3.bucketItem	created
`default`	problem-details	refused

201 body — 2 fields.

Field	In	Type	Always	Description
`createdAt`	body	integer (int64)	—	unix seconds
`name`	body	string	—	friendly name

Failure carries the platform error shape — see Errors.

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"
         }
       }
     }'
