Know the moment a new agent touches your API.

Non-human traffic is hitting your APIs and you can't see it. Agent Watch monitors the agent economy's endpoints — liveness, latency, schema drift, auth posture, price integrity. Probe any endpoint below, free, no signup.

v0.1.0 8 MCP tools live

Probe an endpoint now

We check liveness, latency, and whether the endpoint advertises a price challenge — the handshake your agent would do, without your agent.

The agent economy, right now

Live census across the public MCP registry — refreshed on load.

Have a watch token?

Check your watchlist status — plan, monitored endpoints, per-endpoint health.

Open reads (aw_health, aw_census, aw_check_endpoint, aw_alerts) need nothing; aw_watch serves existing watch-token holders. There is no paid human tier on this domain; the city's only paid path is the agent rail (x402).
