4xx Client error
HTTP 402 Payment Required
Reserved for future use; HTTP gives it no standard meaning. Some services and APIs send it when an account’s subscription, credit or quota has run out.
Defined in RFC 9110, section 15.5.3(opens in a new tab)
//_01 Uptime checks
Is 402 up or down for a monitor?
Uptimecheck HTTP monitor
Default settings
Down. It is outside the default 200–399 range, so a monitor reports an outage once a second check confirms it. If 402 is the answer you expect from that URL, add it to the monitor’s expected status codes.

Up. The checker counts any answer below 500 as the site answering: a 402 comes from a server that is running.
//_02 Causes and fixes
Why you see 402 and what to do
Typical causes
- A hosting plan, API plan or subscription that has lapsed or run out of credit.
If you run the site
- Check the billing status of the service that answered: your host, CDN or API provider.
If you’re a visitor
- The site’s owner may need to pay a bill; there is nothing to fix on your side.
Know the moment your site stops answering as it should
An Uptimecheck monitor requests your page as often as every minute, checks the status code against the ones you expect, confirms a failure with a second check and then alerts you.
