Uptime Promise

Paid accounts are promised 99% API uptime each UTC calendar month, measured by the API check on this page. A month below it pays 10% of that month's charges back as service credit, without anyone asking. Read the Uptime Promise.

How checks work

Every 2 minutes, a scheduled job at Vercel's Washington, D.C. region (iad1) requests https://api.withruntime.com/healthz and counts the check as passed only when it answers HTTP 200 within 8 seconds; it runs outside our servers, so an outage of our host reads as down rather than as silence.

Every 10 minutes, a scheduled job at Vercel's Washington, D.C. region (iad1) uses an account of our own, through the public API like any customer, to create the smallest sandbox, run echo ok in it and stop it, and counts the run as passed only when the sandbox answers running, the command prints ok and the stop is confirmed within 60 seconds; start time runs from the create request to the answer that the sandbox is running.

Uptime is the share of readings taken that passed. An hour or a day with no reading counts as no data, never as up. Each reading is kept for 30 days and each day's totals for good, so the record reaches back to September 23, 2026.

The API is checked every 2 minutes and sandbox starts every 10 minutes. Raw readings use a one-minute cache; their freshness is evaluated for every request. This copy was made at November 8, 2026, 00:32 UTC. For agents: Markdown and JSON.
