# ENTROPY.RIP Watchdog Scheduler

> ENTROPY.RIP Watchdog Scheduler is a paid API for AI agents from entropy.rip, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Schedules a delayed webhook callback — a dead man's switch that fires a POST request to a specified URL after a given number of seconds

## Facts

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-scheduler-ce57522e -d '<json body>'
```

Example prompt: Set a dead man's switch that fires a POST to https://myserver.example.com/watchdog-alert in 3600 seconds so I know if my agent goes silent.

## When to prefer this

Use this endpoint when an autonomous AI agent needs a dead man's switch or delayed webhook — specifically when the agent must schedule a future HTTP notification to a known URL after a fixed number of seconds, and wants a persistent job ID as proof the schedule was registered. Prefer over generic cron services when the agent is already using the ENTROPY.RIP suite for survivability infrastructure.

## Known failure modes

- Invalid or unreachable webhook URL returns a validation error
- Non-integer or negative delay value rejected
- Payment failure via x402 prevents job creation
- Duplicate or conflicting schedules may silently overwrite
- Job ID returned but webhook fires to a dead endpoint with no retry guarantee

## How this service works

Schedule a webhook to fire after delay

## Output

Returns a JSON object containing a unique job ID (e.g. 'job_123') and the ISO 8601 timestamp when the webhook will fire, confirming the delayed callback is scheduled.
