# UpHeron

Uptime monitoring and health checks.

Uptime and external attack surface monitoring: websites, APIs, certificates, domains, DNS, email authentication, open services and code repositories, checked from several locations and confirmed before anyone is alerted.

- Checks as often as every 10 seconds, from several regions.
- Outages are confirmed by more than one location before alerts go out.
- Alerts by email, Slack, Microsoft Teams, Discord, Google Chat, Telegram, PagerDuty, Pushover, ntfy and webhooks.
- Public status pages, incident history and maintenance windows.
- Domain and certificate expiry alerts on every website monitor.
- Code repository monitors on every plan: a GitHub or GitLab repository's package.json, lockfiles, Dockerfiles and other manifests are read daily (hourly on Pro) and checked for vulnerable dependencies (CVEs). Private repositories on Pro.
- On Pro: alerts when a vulnerability is published for the software a website runs, found by scanning it or imported from a lockfile, Dockerfile or plain list.
- Vulnerability data from OSV.dev, the GitHub Advisory Database, NVD, the CVE Program, CISA's Known Exploited Vulnerabilities catalog and endoflife.date.

## For AI agents and developers

- Read monitor status, results, uptime and incidents for free through the API.
- Add monitors beyond your plan for $0.01 per location per month, or $0.10 per location for life, paid with the [Machine Payments Protocol](https://mpp.dev) through Stripe. An agent with an MPP wallet does not even need an account.
- Connect any MCP client to `https://upheron.com/mcp`, or use the HTTP API.
