List releases

Lists the signed binary releases this deployment can serve.

GET /v1/licensing/releases

Licensing → · All API references → · Get started →

Address	`https://api.hanzo.ai/v1/licensing/releases`
Method	`GET`
Operation	`get_licensing_releases`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Lists the signed binary releases this deployment can serve.

Metadata only, and no download URL: the artifact is behind GET /v1/licensing/download/{release}, which is gated on a valid license token. Knowing that a release exists is not permission to run it, which is why this list needs no license of its own.

Request

GET /v1/licensing/releases takes no parameters and no body — the credential is the whole request.

Response

Status	Body	Meaning
`200`	licensing.ReleaseList	ok
`default`	problem-details	refused

200 body — 13 fields.

Field	In	Type	Always	Description
`releases`	body	licensing.Release[]	—	Releases is the published releases, always an array and never null.
`releases[].app_id`	body	string	—	AppID scopes the release to an app build ("hanzo" \| "lux" \| "zoo").
`releases[].artifact_ref`	body	string	—	ArtifactRef is where the binary lives (object-store key / OCI ref / path).
`releases[].cosign_cert`	body	string	—	CosignCert is the cosign/Fulcio cert (keyless) or public key ref used to verify CosignSignature.
`releases[].cosign_signature`	body	string	—	CosignSignature is the base64 cosign signature over the artifact digest.
`releases[].created_at`	body	integer (int64)	—
`releases[].id`	body	string	—	ID is the release identifier, e.g. "engine-rocm-0.4.2-linux-amd64".
`releases[].min_features`	body	string[]	—	MinFeatures, when set, are features the license must include to download.
`releases[].platform`	body	string	—	Platform is "<os>/<arch>", e.g. "linux/amd64".
`releases[].product`	body	string	—	Product is the licensed product this artifact belongs to (commerce SKU): "engine" for every one of those builds.
`releases[].sha256`	body	string	—	SHA256 is the hex digest of the artifact (integrity + cosign subject).
`releases[].version`	body	string	—	Version is the semantic version of the binary.
`releases[].yanked`	body	boolean	—	Yanked marks a pulled release (download refused; tokens may be revoked release-scoped too).

Failure carries the platform error shape — see Errors.

MCP reaches licensing through the licensing tool, which names its 9 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": "get_licensing_download"
         }
       }
     }'
