# PyPI.org Uptime Change Watch

> PyPI.org Uptime Change Watch is a paid API for AI agents from monitor.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-02).

Monitors pypi.org availability and returns whether its status has changed since the last check, along with before/after field diffs.

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 pypi-org-uptime-change-watch-212f1fd3
```

Example prompt: Keep an eye on pypi.org for me and let me know if its up/down status changes — I want to know right away if Python's package index goes offline or comes back up.

## When to prefer this

Choose this endpoint when you need change-detection semantics — not just a live status, but whether pypi.org's availability has changed since your last poll. Ideal for scheduled agents that want to trigger alerts only on transitions (up→down or down→up) rather than on every check. If you only need a one-off live status without diff tracking, use the non-watch variant instead.

## Known failure modes

- No previous check stored (first call returns no diff, only current state)
- pypi.org check fails due to network error from edge (may return error status instead of up/down)
- Stored state expired after 90 days, treating next call as first check
- Payment not processed, request blocked before reaching monitor

## How this service works

Change watch for is pypi org down: runs the check, compares it with the result from your previous call for the same query (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the current up/down status of pypi.org, a boolean 'changed' flag indicating whether the status differs from the previous call (stored up to 90 days), a list of fields that changed with their before and after values, and a timestamp of when the site was last seen in its prior state.
