n8n

Error Workflows only fire when a node errors. A workflow that runs, does nothing, and exits green is invisible. RunVouch adds expected-cadence, evidence and cost per run.

The community node

Install n8n-nodes-runvouch from Settings, Community Nodes, Install, add a RunVouch API credential with your key, and use two nodes: Start Run after the Schedule Trigger and End Run at the end with status and evidence, or a single Heartbeat node. The first run registers the agent with the cadence you set in the node. Source, README and an importable example workflow: integrations/n8n-nodes-runvouch; details on the integration page.

Two HTTP Request nodes

At the start: POST https://api.runvouch.com/v1/runs/start with header X-API-Key and body {{"agent":"lead-enricher","source":"n8n"}}; save run_id. At the end: POST https://api.runvouch.com/v1/runs/end with status, cost (from your OpenAI/Anthropic node usage) and evidence such as {{"rows_written": true}}.

Cadence

rv agent lead-enricher --cadence 1h --grace 15m --cap-day-cost 5

Now a workflow that stops being triggered, or quietly returns nothing, alerts you.
