# Email Domain Intel Change Watch

> Email Domain Intel 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).

## 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 email-domain-intel-change-watch-8e7f6bea
```

Example prompt: Keep an eye on the domain intel for john.doe@acmecorp.com and let me know if the company or any other domain fields change since the last time you checked.

## When to prefer this

Use this endpoint when you need automated change detection on email-to-company/domain intelligence over time, rather than a one-shot lookup. It is ideal for scheduled agent workflows that need to react to organizational changes (company rebrands, domain transfers, MX record shifts) associated with specific email contacts. Prefer it over a plain email domain lookup when you need the diff — before/after field comparison — rather than just the current value.

## Known failure modes

- No previous result exists (first call for this email, so changed=false or no diff available)
- Email address not recognized or unparseable domain
- Domain intel unavailable for the given domain
- Previous result expired after 90-day retention window, treated as first call
- Rate limiting or payment failure at $0.01 per check

## How this service works

Change watch for email domain intel: 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 from an email address to its company changes. $0.01 per check.

## Output

Returns the current domain intel result for the email address, a boolean indicating whether anything changed since the previous call, a list of exactly which fields changed with their before and after values, and a timestamp of when the record was last seen. Previous results are retained for 90 days.
