## 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 twilio-com-downtime-change-watch-aa278c71
```

Example prompt: Keep an eye on twilio.com for me and let me know if its up/down status changes from what you last saw — I want to be alerted the moment it goes down or comes back up.

## When to prefer this

Use this endpoint when you need change-aware monitoring of twilio.com — specifically when you care not just about the current status but whether it has changed since your last poll. Ideal for scheduling recurring checks and triggering alerts only on transitions (up→down or down→up), avoiding noise from repeated same-state results. Prefer over a plain is-down check when building event-driven alerting workflows.

## Known failure modes

- No previous result stored (first call in 90-day window) — 'changed' may default to true or be undefined
- Twilio.com itself returns ambiguous or partial responses making up/down determination uncertain
- Payment failure via x402 protocol results in no check being performed
- Network timeout reaching twilio.com from Cloudflare edge means status may be inconclusive
- Stale comparison if 90-day stored result has expired

## How this service works

Change watch for is twilio com 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 twilio.com, a boolean 'changed' flag indicating whether the result differs from the previous call stored for up to 90 days, a list of fields that changed with their before and after values, and a timestamp of when the status was last seen.
