Auth	`Authorization: Bearer $HANZO_API_KEY`

Sends one request on the org's bus and waits for one reply — the synchronous half of pub/sub, for callers speaking to a responder subscribed on the NATS port. 404 when nobody is listening on the subject; 408 when a responder exists but no reply arrived within the timeout.

Request

5 fields, body application/json (required).

Field	In	Type	Required	Description
`data`	body	string	—	Data is the request payload, carried verbatim as UTF-8 text.
`headers`	body	object	—	Headers are optional request headers, one value per name.
`headers.*`	body	string	—
`subject`	body	string	—	Subject is the subject a responder listens on, in the org's namespace.
`timeoutMs`	body	integer (int64)	—	TimeoutMs bounds the wait for a reply.

Response

Status	Body	Meaning
`200`	pubsub.busMessage	ok
`default`	problem-details	refused

200 body — 6 fields.

Field	In	Type	Always	Description
`data`	body	string	—	Data is the payload as UTF-8 text.
`headers`	body	object	—	Headers are the message's headers, when it carries any.
