# Email Provider Detect Watch

> Email Provider Detect 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-provider-detect-watch-5767a94a
```

Example prompt: Keep an eye on the email provider for acme.com — check it on a schedule and let me know if the provider ever changes, including what it was before and what it changed to.

## When to prefer this

Choose this endpoint when you need to be notified of changes in email provider detection over time rather than just performing a one-off lookup. It is ideal for scheduled monitoring pipelines, sales intelligence workflows, or infrastructure change alerting where you want structured diffs (before/after field values) and a change flag rather than raw current state.

## Known failure modes

- Email or domain not resolvable — returns error or null provider
- No prior call stored — first call has no diff, changed=false by default
- Results older than 90 days are purged — comparison resets
- Payment not fulfilled — request rejected due to x402 payment requirement
- Rate limiting or network errors reaching the provider's detection backend

## How this service works

Change watch for email provider detect: 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 email provider detection for an address or domain changes. $0.01 per check.

## Output

Returns the current detected email provider, a boolean indicating whether the result changed since the last call, a list of exactly which fields changed with before and after values, and a timestamp of when the result was last seen. Historical comparison is retained for 90 days.
