Before you scrape a job posting, Shopify or HTML product page, or eBay item, POST the specific URL you already have and Livecheck returns live, closed, or unknown plus title and signals (apply form, in-stock, sold-out, 404); not a search engine. Price is $0.01 USDC on Base per request.

The 402 response includes a payment-required header (x402 v2, Stripe deposit address, USDC on Base).

Confirm for operators

How do you know the agent actually did it?

A success toast and a calendar invite aren’t proof. Livecheck Confirm checks the real-world result — independently.

Watch the Confirm demo.

Live stats

Includes internal test traffic. Headline watchers, checks, and confirm windows are all wallets. traffic.external omits configured team wallets.

Source of truth: GET /stats?format=json (https://livecheck.fly.dev/stats?format=json). On Fly that document sums started machines' volumes, so the strip does not flip between live Sentinel counts and an empty volume. Gil owns landing copy — this strip only fetches that JSON.

Loading /stats?format=json…

Not a search engine. Not an aggregator copy. HTML + status only — no page JS in v1. Paid route is POST /v1/verify. Free: GET /, GET /health, and GET /stats?format=json. Mock header livecheck-dev is ignored when live keys are set.
