Address	`https://api.hanzo.ai/v1/principal/keys`
Method	`GET`
Operation	`get_principal_keys`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Publishes the keys attestations are signed with, as a JSON Web Key Set (RFC 7517; Ed25519 keys as RFC 8037 writes them). Open to anyone: a verifier verifying an agent's statement fetches this once and verifies offline.

A key a rotation retired stays here and signs nothing, so a statement signed before the rotation verifies until it expires.

Request

GET /v1/principal/keys takes no parameters and no body — the credential is the whole request.

Response

Status	Body	Meaning

MCP reaches principal through the principal tool, which names its 7 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_principals"
         }
       }
     }'
