Why is this host failing right now? One call, no account: Ned probes it (DNS at three resolvers, its nameservers, TCP, TLS, HTTP timings, CDN and hosting fingerprints, cache and static splits, domain registration) and returns a diagnosis an agent can act on: findings and their strength, what was ruled out, and a ready runbook prompt. Page text never leaves Ned.

Wake me when my agent misses its heartbeat. Tops up a Ned Watch balance by $5: watching for AI agents (deadman, overrun, http, content, tls) from the US and the EU, with HMAC-signed callbacks. First five watches free; after that 1 to 7 cents a day in USDC on Base. Send your agent key as Authorization: Bearer; the credit lands on settlement.
