--- title: WatchFor — uptime & infrastructure monitoring description: Modern monitoring for humans and AI agents: 25 check types, confirmed alerts, on-call and public status pages. From one website to millions of endpoints. canonical: https://watchfor.io/ --- # WatchFor *Watch for anything on the internet.* WatchFor is modern uptime and infrastructure monitoring for humans and AI agents: 25 check types — HTTP/HTTPS, APIs, MCP servers, SSL/TLS, DNS, TCP/UDP, ping, MTR, email, Core Web Vitals, heartbeat/cron check-ins and more — run from 20 locations across 7 regions, with **confirmed alerting** (a failure is only "Down" once confirmed from several locations, so fewer false alarms), incidents with on-call and escalations, post-mortems, reports, 16+ notification channels, and public status pages on your own subdomain. Everything in the dashboard is also available to AI agents through the REST API, MCP server and A2A. It starts with one URL on a genuinely useful free plan and scales to millions of endpoints; paid plans cost significantly less than legacy competitors. ## What you can do - **Monitor** websites, APIs, servers and networks from the outside — nothing to install. - **Get confirmed alerts** to Slack, Discord, Telegram, Teams, PagerDuty, Opsgenie, webhooks and more. - **Publish a status page** on `yourname.watchfor.io` with incidents, maintenance and uptime history. - **Run on-call** rotations, escalation policies and incident management. ## For AI agents & developers ### API & protocols - **REST API:** `https://watchfor.io/api/v1` — OpenAPI 3.1: https://watchfor.io/openapi.json (66 operations) - **MCP server** (45 tools, Streamable HTTP): `https://watchfor.io/api/mcp` — manifest: https://watchfor.io/.well-known/mcp.json - **A2A agent** (16 skills, JSON-RPC): `https://watchfor.io/api/a2a` — Agent Card: https://watchfor.io/.well-known/agent-card.json - **Live diagnostics** (22 on-demand checks from the probe fleet, any public target): `https://watchfor.io/api/v1/diagnostics` — [docs](https://watchfor.io/docs/api/diagnostics) - **In-page WebMCP** (9 read-only/navigational tools on `document.modelContext`, registered by the marketing pages for agentic browsers) - **NLWeb /ask** (natural-language query): `https://watchfor.io/ask` - **Monitor-type catalog:** https://watchfor.io/api/v1/meta/monitor-types - **API catalog (RFC 9727):** https://watchfor.io/.well-known/api-catalog ### Authentication - **API key:** `Authorization: Bearer wf_live_…` (Settings → API keys; `read`/`write` scopes) - **OAuth 2.1:** https://watchfor.io/.well-known/oauth-authorization-server (dynamic client registration + PKCE, no manual key) - **Walkthrough:** https://watchfor.io/auth.md - **Free tier, self-serve keys, zero-auth discovery** (MCP initialize / tools-list, A2A card, OpenAPI all respond without a key).
