Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| message | string | yes | UTF-8 message to sign. |
| service | any | no | Sign with this service-derived key instead of your root identity (e.g. 'github.com') — must already exist via bardo_derive. |
| session_token | any | no | Bardo session token, only needed if this call's identity was established somewhere other than this exact connection (a plain HTTP/curl solve, a previous conversation, a different MCP connection). Omit it if this connection already called bardo_solve. |
