How we check
Up means the endpoint answered an unpaid test request with a valid x402 payment challenge. We never pay, so we can't see whether the paid response works.
Checks come from our server, about every 4 hours for this listing over the last 7 days. A failure can also mean the service blocks our checks. Two failed checks in a row count as an outage, which ends at the next passing check.
