One price, no surprises

$0.0005
per delivered check

That's the whole price list. One flat rate, in USDC, for each check delivered to you — no subscription, no account, no tiers to jump between. You build the schedule; the total is just your check count times half a tenth of a cent.

The model

You pay per check delivered

Not per "monitor per month," not per seat, not a plan you pick and hope you sized right. PingDog prices in something you can count: one check delivered to you, at a single flat rate. Build any schedule you like and the price is exactly its total number of checks times that rate.

price = total checks × $0.0005
Every paid monitor costs its delivered-check count times a single flat rate. That is the entire formula. Check less often, run for less time, or add a UTC window and day mask, and the price falls in direct proportion — no minimums, no seats, no plan to outgrow.

Pay once, not per month

One USDC payment for the monitoring you configured, to a single-use address. Nothing renews, nothing recurs, and there's no account to cancel. A schedule that runs "for 20 weeks" is paid up front — the weeks are a shape for the checks, never a subscription.

Fixed, never shared out

The rate is the same whether you buy a thousand checks or a million, and it never depends on how many other people watch the same target. Thanks to poll-once-fan-out we serve many customers from one probe — but your price is fixed per delivered check, always predictable.

Real numbers

What real monitoring costs

These are worked from the actual rate — checks × $0.0005. The builder shows your exact figure live as you drag; these just anchor your intuition for the scale.

How the math works: count the checks a schedule fires, multiply by $0.0005. A 5-minute interval, 24/7, is 288 checks a day; over 6 months (≈ 182.5 days) that's 52,560 checks × $0.0005 = $26.28. A 1-minute schedule for 12 UTC hours on Mon/Wed/Sat is 720 × 3 = 2,160 checks a week; across 20 weeks that's 43,200 × $0.0005 = $21.60. The builder does this live and shows the exact USDC amount before you pay.
Zero cost

A real free tier

Not a trial that expires into a paywall and not a locked demo — the same builder, run in its zero-cost range. No payment, no wallet, no account.

Free while you stay within the floors: up to 3 monitors, checked no faster than every 5 minutes. That's genuine monitoring you can run to watch a few things — and to check us — before sending any payment. Cross either floor (a faster interval, or a fourth target) and the order simply becomes a paid one, priced by the checks you added at $0.0005 each. Scheduling controls are available free too, since they only lower load.
Payment

How you pay

  • Paid monitoring is settled once, up front, in USDC — a US-dollar stablecoin — on Base.
  • Each order generates its own single-use address, shown as a QR code, a one-tap wallet link, and a copyable amount + address; you send the exact amount, and monitoring dispatches on confirmation.
  • No card, no account, no KYC, no wallet linking. We're non-custodial — we read a public blockchain to confirm your payment, nothing more.
  • All sales are final — there's no subscription to cancel and no refunds. See the Terms for the full detail.
