Dead credentials, rate limits, and quota warnings arrive as email verdicts with a stable failure_class.\n\n**How to set up (5 min)**\n1. Install the **Apify** community node (n8n Cloud: search \"Apify\" in the nodes panel and install) and connect your Apify account.\n2. Open **Initiate Datasource Pulse** and edit *Input JSON*: paste your real keys. 35+ vendors come pre-wired (OpenAI, Anthropic, Stripe, GitHub, SerpAPI and more, see the actor README for per-vendor fields), plus generic_http for any endpoint you add.\n3. `quotaSoftCap` is YOUR budget line in the vendor's native unit (searches for SerpAPI, USD for Apify).\n4. Set your address in **Send Gmail Alert**, connect Gmail, run once.\n\n**Requirements**\nApify account ($0.02 per key per run), the Apify community node (verified on n8n Cloud; self-hosted installs @apify/n8n-nodes-apify), a Gmail connection, the API keys you want watched.\n\n**How to customize**\nThe pre-wired list is a head start, not a limit: any other authenticated HTTP endpoint can be watched with a generic_http check. Tune quotaWarningPct (default 80) and the schedule. Cost: 3 keys at 1 run/day is about $1.83/month.\n\nDocs: https://datasourcepulse.com/integrations/n8n",
