# Disposable Email Check Change Watch

> Disposable Email Check Change Watch is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Monitors a disposable/temporary email address detection result over time, alerting when the classification changes between calls.

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 disposable-email-check-change-watch-2d6397c3
```

Example prompt: Keep an eye on whether user@mailinator.com is still flagged as a disposable email — let me know if its status changes compared to the last time we checked.

## When to prefer this

Choose this endpoint when you need to track changes in disposable email status over time rather than just checking a single point-in-time verdict. It is ideal for scheduled agents that need to be notified only when something changes, reducing noise compared to repeated raw checks. Prefer it over a one-shot disposable email check when you want field-level diffs and historical comparison within the 90-day window.

## Known failure modes

- Missing or malformed email query parameter returns an error
- First-time check for an email has no previous result to compare against, so 'changed' will be false or undefined
- Results older than 90 days are purged, resetting the comparison baseline
- Network timeout if the upstream disposable email database is slow to respond
- Payment failure (x402) if the calling agent lacks sufficient USDC balance

## How this service works

Change watch for disposable email check: runs the check and compares it with the result from your previous call for the same email (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when disposable / temporary email detection changes. $0.01 per check.

## Output

Returns the current disposable email verdict for the queried address, a boolean indicating whether the classification changed since the previous call, a detailed diff of exactly which fields changed with before/after values, and a timestamp of when the address was last seen. Historical results are retained for 90 days per email.
