HOW IT WORKS

Up and running in 3 minutes.

Register your API

Paste any endpoint URL — Stripe, OpenAI, HubSpot, Twilio, or any REST API. Set your expected response and thresholds.

Connect your team

Add your Slack or Discord webhook. Your entire team gets notified the moment something breaks — before customers notice.

Sleep well

We ping every 60 seconds. If the status, payload, or response time changes, you're the first to know — not your customers.

FEATURES

Everything you need to protect your integrations.

60-second ping interval

We monitor your APIs every minute, 24/7. No lag, no gaps.

Slack & Discord native

Instant alerts where your team already works. No new app to check.

Schema change detection

We validate payload structure, not just status codes. Know when a field disappears.

Public SLA report

Share a public uptime page with your customers or use it to hold vendors accountable.

Multi-API dashboard

All your critical dependencies in one place. Incident history, trends, response times.

Escalation policies

Alert Slack first. If unacknowledged in 5 minutes, escalate to email or a different channel.

FAQ

Common questions.

Those tools check if your server is up. We monitor the APIs you depend on — third-party services like Stripe, OpenAI, or HubSpot — and validate that their responses match what your code expects. A 200 OK with a broken payload will fool uptime monitors but not us.

Any REST API endpoint. Public APIs like Stripe, OpenAI, HubSpot, Twilio, Shopify, SendGrid — or your own internal services.

We ping every 60 seconds. From the moment an API fails, you'll have an alert in your Slack or Discord within 2 minutes.

No. You provide a URL, expected status code, and optionally a JSON schema to validate. No SDKs, no config files.
