# StubHub Uptime Checker

> StubHub Uptime Checker is a paid API for AI agents from monitor.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Performs a live HTTP check from Cloudflare's edge to determine if stubhub.com is currently up or down, returning status, response time, redirect URL, server header, and TLS certificate validity.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability stubhub-uptime-checker-880d74fa
```

Example prompt: Can you check if stubhub.com is actually down right now or if the problem is just on my end — I'm trying to buy tickets but the site won't load.

## When to prefer this

Use this endpoint when a user reports stubhub.com is inaccessible and you need to distinguish between a global outage and a local connectivity issue. It is specifically scoped to stubhub.com and provides TLS and redirect metadata beyond a simple ping. Prefer it over generic uptime tools when you need a stubhub-specific verdict with minimal cost ($0.01/check).

## Known failure modes

- stubhub.com is genuinely down — returns down verdict with last known HTTP status
- TLS certificate invalid or expired — check fails with cert error
- DNS resolution failure — endpoint cannot reach stubhub.com
- Request timeout — response time exceeds threshold and returns down verdict
- Cloudflare edge probe itself has an issue — may return inconclusive result

## How this service works

Is stubhub.com down right now? Live check from Cloudflare's edge: HTTP status, response time, final URL after redirects, server header and whether the TLS certificate is valid, with an up/down verdict. Call it when a user or agent says "stubhub.com isn't loading" to tell a real outage from a local problem. $0.01 per check.

## Output

Returns an HTTP status code, response time in milliseconds, the final URL after any redirects, the server header value, TLS certificate validity, and a clear up/down verdict indicating whether stubhub.com is accessible from Cloudflare's edge.
