List datasets

The datasets your org has, each with its name, description, metadata and timestamps.

GET /v1/eval/datasets

Address	`https://api.hanzo.ai/v1/eval/datasets`
Method	`GET`
Operation	`get_eval_datasets`
Auth	`Authorization: Bearer $HANZO_API_KEY`

The datasets your org has, each with its name, description, metadata and timestamps.

It is the only way to enumerate what an org holds. Requires a validated principal; 401 without one. Every row is filtered on the validated org, so there is no parameter that reaches another tenant's datasets. The item count is NOT populated here — read one dataset to get it.

Request

1 field.

Field	In	Type	Required	Description
`limit`	query	integer	—	Limit caps the rows returned.

Response

Status	Body	Meaning
`200`	eval.datasetList	ok
`default`	problem-details	refused

200 body — 8 fields.

Field	In	Type	Always	Description
`data`	body	eval.datasetView[]	—	Data is the caller org's datasets, newest first, bounded by limit.
`data[].createdAt`	body	string	—	CreatedAt is when the name was first written, kept across later edits.
`data[].description`	body	string	—	Description is free text the org wrote about what this set measures.
`data[].items`	body	integer (int64)	—	Items is how many examples the set holds.
`data[].metadata`	body	object	—	Metadata is the free-form object stored with the set, echoed back verbatim.
`data[].metadata.*`	body	any	—
`data[].name`	body	string	—	Name is the dataset's org-unique handle and the segment that addresses it.
`data[].updatedAt`	body	string	—	UpdatedAt is when the description or metadata last changed.

Failure carries the platform error shape — see Errors.

MCP reaches eval through the eval tool, which names its 16 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_eval_datasets"
         }
       }
     }'
