Checkly service levels

Figures are quoted from the pages listed in sources. Guarantees are what the provider promises. Observed figures are what the provider reports about itself. APIs.io runs no monitors and has not measured or verified any of them. Read 2026-11-02.

Promised uptime

Commitments on the provider's own SLA page.

Not checked: we hold no SLA page for this provider.

Reported uptime
