Uptime Check API

GET /api/uptime $0.002 per call USDC on Base · x402

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.

Parameters

Name	In		Description
`url`	query	required	Public http(s) URL to check, e.g. https://example.com

Example request

curl "https://api.webbersites.com/api/uptime?url=https%3A%2F%2Fexample.com"
# first call returns 402 + payment requirements; an x402 client pays and retries automatically

MCP tool: get_uptime — via npx -y webbersites-x402-mcp (local, key stays on your machine) or the remote endpoint https://api.webbersites.com/mcp.

How payment works

There is no signup and no API key. Call the endpoint; it replies 402 Payment Required with machine-readable payment requirements. Your client signs a USDC transfer authorization (EIP-3009, gasless) and retries with the X-PAYMENT header — @x402/fetch does this automatically. See the overview for a working snippet.
