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

Publishes the Ed25519 PUBLIC verification key, at both /pubkey and /jwks.

This is the only public-safe surface here and the reason the whole scheme works offline: the engine embeds or fetches this key once and then verifies every license itself, with no call home per launch. The private half lives in KMS, so nothing served here is a secret. provider names where that half lives: "kms" is the production key every engine embeds; "local" is a development key, and a token signed by one is not a production credential.

Request

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

Response

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

200 body — 10 fields.

Field	In	Type	Always	Description
`alg`	body	string	—	Alg is always "Ed25519".
`keys`	body	licensing.JWK[]	—	Keys is the same key as a single-entry JWKS (OKP/Ed25519), for JWKS-shaped consumers.
`keys[].crv`	body	string	—	Crv is always "Ed25519".
`keys[].kty`	body	string	—	Kty is always "OKP".
`keys[].use`	body	string	—	Use is always "sig".
`keys[].x`	body	string	—	X is the public key, base64url (the JWK convention).
`provider`	body	string	—	Provider names where the private half lives: "kms" (production) or "local" (a development key — never trust it in production).
`public_key`	body	string	—	PublicKey is the 32-byte Ed25519 public key, standard base64.
`schema`	body	integer (uint8)	—	Schema is the license payload schema version this key signs.
`token_format`	body	string	—	TokenFormat states the wire layout so an implementer can verify a token without this service's source.

Failure carries the platform error shape — see Errors.
