Site Health Report API

GET /api/uptime/report $0.01 per call USDC on Base · x402

Deep uptime & health report from one socket-level HEAD probe: DNS/TCP/TLS/TTFB timing waterfall, TLS certificate (issuer, expiry countdown, trust status), HTTP/2 support via ALPN, server IP + hosting location, CDN detection, redirect chain, caching + security response headers, compression, server clock skew. On failure, says exactly which phase died. Everything a monitor needs in one deterministic call — no page download.

Parameters

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

Example request

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

MCP tool: get_uptime_report — 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.
