What “down” means here

  • Up: any answer below HTTP 500 (except 404/410) within 8 seconds. A healthy x402 endpoint answers an unpaid call with HTTP 402 and its price.
  • A failed check: no answer within 8 seconds, an HTTP 5xx error, or 404/410 (endpoint gone).
  • Down: 2 or more failed daily checks in a row. One failure alone is not counted.
  • Check unavailable: HTTP 525 is a TLS error on our checker’s side. It is never shown as down.

Check StableUpload yourself

The same unpaid request we send. It costs nothing: without a payment header nothing is charged.

curl -i -X POST "https://stableupload.dev/api/upload"

HTTP 402 with a payment request: up and asking for payment. HTTP 5xx, 404/410 or no answer: failing. Our median for this endpoint is 391 ms.

StableUpload status FAQ

Is StableUpload down right now?

No. StableUpload's paid endpoint answered our last check on Nov 9, 2026, 10:50 AM ET with a valid x402 payment request.

When was StableUpload last down?

We have not recorded an outage since we started checking on Oct 27, 2026: all 14 daily checks so far were up. A short outage between two daily checks would not show here.

How fast does StableUpload respond?

391 ms (median, last 7 days); 390 ms (median, all 15 days so far), measured as time to the response headers of our unpaid request. The last check took 235 ms.

Is StableUpload down for everyone or just me?

We check from our own server once a day, so if it answered us but fails for you, the problem may be on your side (network, wallet, a different route) or a short outage after our check. You can test it yourself with the curl command on this page: an HTTP 402 answer means the endpoint is up and asking for payment.

What counts as down?

Down means no answer within 8 seconds, an HTTP 5xx error, or 404/410 (endpoint gone). We list a service as down only after 2 failed daily checks in a row. An HTTP 525 is a TLS error on our checker's side and is shown as "check unavailable", never as down.
