# UpHeron

Uptime monitoring and health checks.

> Uptime and external attack surface monitoring for websites, APIs, certificates, domains, DNS, mail servers and code repositories, from several locations, with vulnerability (CVE) alerts. AI agents read status for free through the API and pay for extra monitors (per location, monthly or for life) with the Machine Payments Protocol (HTTP 402) through Stripe. No account is needed to buy a monitor.

API base: https://upheron.com/api/v1 · MCP server: https://upheron.com/mcp · authenticate with the X-API-Key header, or get access yourself with auth.md: https://upheron.com/auth.md · every page is available as Markdown with Accept: text/markdown or a .md suffix.
