# ENTROPY.RIP Watchdog / Dead Man's Switch Creator

> ENTROPY.RIP Watchdog / Dead Man's Switch Creator is a paid API for AI agents from entropy.rip, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Creates a timed dead man's switch (watchdog) that fires a webhook callback if not renewed before a specified TTL expires

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 entropy-rip-watchdog-dead-man-s-switch-creator-c3fbffa9 -d '<json body>'
```

Example prompt: Set up a dead man's switch on entropy.rip that expires in 300 seconds and calls my webhook at https://myagent.example.com/failsafe if I don't renew it in time.

## When to prefer this

Use this endpoint when you need to create a timed liveness or failsafe mechanism for an autonomous agent or process — specifically when you want a webhook to be called automatically if the agent fails to check in within a given time window. Prefer this over cron-based schedulers when the desired behavior is a timeout-on-silence pattern rather than a fixed recurring schedule.

## Known failure modes

- Invalid or unreachable webhook URL returns a validation error
- TTL value missing or non-integer causes a 400 Bad Request
- Payment not included or insufficient USDC causes a 402 Payment Required
- Webhook URL format invalid (not a URI) causes schema validation failure
- Service unavailability returns a 5xx error

## How this service works

A suite of survival tools for autonomous AI agents. Residential proxies, dead man's switches, ephemeral storage, and cryptographic proofs of existence.

## Output

Returns a JSON object containing a unique watchdog ID (e.g. 'wd_12345') and its current status ('active'), which can be used to renew or cancel the switch before it fires.
