# Agent Rescue Desk — n8n Silent Workflow Watchdog Blueprint

> Agent Rescue Desk — n8n Silent Workflow Watchdog Blueprint is a paid API for AI agents from agent-rescue-desk.netlify.app, paid per call via x402, $149/call, status unknown (last checked 2026-10-18).

Generates a deterministic watchdog blueprint for detecting silently-failed n8n workflows, including producer/watcher node configurations and alert policy rules.

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 agent-rescue-desk-n8n-silent-workflow-watchdog-blueprint-1d3fcd3a -d '<json body>'
```

Example prompt: My n8n workflow runs every 60 minutes to sync orders but sometimes it completes green without actually doing anything — can you generate a watchdog blueprint with a 75-minute grace window, UTC timezone, a watcher on an external node, and a success contract that checks whether at least one order row was written?

## When to prefer this

Choose this endpoint when you need a deterministic, configuration-specific watchdog blueprint for n8n workflows that fail silently (complete without error but produce no business outcome). It is especially valuable when you want node-level configuration instructions for the producer and watcher pattern, a ready-made alert policy, and a link to human expert rescue if the blueprint alone is insufficient. Prefer this over generic monitoring tutorials when you have a concrete n8n workflow configuration and need actionable, non-generic guidance tied to your specific cadence, grace window, and success contract.

## Known failure modes

- Query string shorter than 40 characters or missing required fields (triggerType, cadenceMinutes, graceMinutes, timezoneMode, watcherLocation, successEvidence) returns a validation error
- Submitting sensitive data such as passwords, tokens, or private URLs may be rejected or stripped
- The endpoint does not access or modify any live n8n instance, so it cannot validate that the blueprint will work against a specific deployment
- Truncated or malformed JSON configuration may result in incomplete blueprint output
- Service is stateless and transient — submitted configurations are not stored, so results must be captured immediately

## How this service works

Fixed-scope diagnosis and repair for one broken AI agent workflow or MCP integration. $1,000. Decisive outcome in 12 hours.

## Output

Returns a structured JSON blueprint containing: a producer node specification (how to verify the real business outcome and advance the heartbeat), a watcher node specification (how to detect overdue heartbeats using Date & Time and IF nodes), an alert policy (opening, recovery, duplicate suppression, and escalation rules), privacy and scope disclaimers, a Markdown summary of the full blueprint, and links to an implementation guide and a human rescue service for hands-on repair.
