Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability deadman-switch-ping-onchain-trading-intelligence-platform-c1f442ea -d '<json body>'
```

Example prompt: Ping my deadman switch with switch ID 'switch-abc123' and token 'my-secret-token-xyz' so it doesn't trigger.

## When to prefer this

Use this endpoint when you need to keep a deadman switch alive from within an automated agent loop — specifically when the switch was created on this onchain intelligence platform and requires a secret token for authentication. Not for general health checks or external monitoring services.

## Known failure modes

- Invalid or expired token returns authentication error
- Unknown switch ID returns not-found error
- Network timeout if the Railway deployment is unreachable
- Missing required fields (id or token) returns validation error

## How this service works

Dead-man's switch: heartbeat to keep the switch from firing. Send { id, token }.

## Output

Returns an acknowledgment confirming the deadman switch was successfully pinged and its timer reset; may include switch status or timestamp of last ping.
