# Send one test watch notice to your relay inbox

`POST /v1/agent/watches/{id}/test-notice`

## Request

- Base URL: `https://api.voidly.ai`
- URL: `https://api.voidly.ai/v1/agent/watches/{id}/test-notice`
- Auth: API key in header `X-Agent-Key`

For a watch with inbox delivery on, Voidly's watch notice sender writes one test notice (schema voidly.watch-notice.v1) to this identity's relay inbox. Read it with GET /v1/agent/receive/raw and open it locally with nacl.box.open, the sender's encryption key and your own X25519 secret key. Voidly writes the notice, so Voidly can read it: it is not end-to-end encrypted. At most 3 test notices per identity per 24 hours. Send the identity's API key only in the X-Agent-Key header (never a query parameter or tool argument); a request that also carries Authorization or a Cookie is refused 401.

## Path parameters
