# Uptime/health probe for any public URL

`GET /api/uptime`

## Request

- Base URL: `https://api.webbersites.com`
- URL: `https://api.webbersites.com/api/uptime`
- Auth: API key in header `X-PAYMENT`

Uptime/health probe for any public URL: sends a HEAD request (auto GET fallback when the server refuses HEAD), follows redirects with per-hop safety checks, and returns up/down, HTTP status, latency in ms, redirect chain, final URL, and key response headers. Deterministic, no page download — a monitoring probe agents can call on a schedule.

Price: $0.002 per call, paid in USDC via the x402 protocol (see the x402 security scheme).
