AuthAuthorization: Bearer $HANZO_API_KEY

Reads one release's metadata: its product, version, platform and the cosign material a client verifies the binary against.

An unknown id is 404. Like the list, this is metadata only — the bytes are behind the license-gated download.

200 body — 12 fields.

FieldInTypeAlwaysDescription
app_idbodystring—AppID scopes the release to an app build ("hanzo" | "lux" | "zoo").
artifact_refbodystring—ArtifactRef is where the binary lives (object-store key / OCI ref / path).
cosign_certbodystring—CosignCert is the cosign/Fulcio cert (keyless) or public key ref used to verify CosignSignature.
cosign_signaturebodystring—CosignSignature is the base64 cosign signature over the artifact digest.
created_atbodyinteger (int64)—
idbodystring—ID is the release identifier, e.g. "engine-rocm-0.4.2-linux-amd64".
min_featuresbodystring[]—MinFeatures, when set, are features the license must include to download.
platformbodystring—Platform is "<os>/<arch>", e.g. "linux/amd64".
productbodystring—Product is the licensed product this artifact belongs to (commerce SKU): "engine" for every one of those builds.
sha256bodystring—SHA256 is the hex digest of the artifact (integrity + cosign subject).
versionbodystring—Version is the semantic version of the binary.
yankedbodyboolean—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"
         }
       }
     }'
