> SPF Flatten 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).

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 spf-flatten-change-watch-09403a94
```

Example prompt: Check whether the SPF flatten result for example.com has changed since the last time you ran it, and tell me exactly which fields changed with the before and after values.

## When to prefer this

Choose this endpoint when you need to continuously monitor SPF flattener output for a domain and want automated change detection with structured before/after diffs, rather than manually comparing raw SPF flatten results yourself. Ideal for scheduled agent workflows that need to alert on DNS email configuration drift.

## Known failure modes

- Domain not found or invalid domain name provided
- No previous result stored (first call for this domain returns current result with no diff)
- DNS lookup failure for the target domain
- Previous result expired beyond the 90-day retention window causing a fresh baseline
- Payment not processed resulting in 402 response
- Rate limiting or service unavailability

## How this service works

Change watch for spf flatten: runs the check and compares it with the result from your previous call for the same domain (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 spf flattener changes. $0.01 per check.

## Output

Returns the current SPF flatten result for the domain, a boolean 'changed' flag indicating whether it differs from the previous call, a detailed diff of exactly which fields changed with their before and after values, and the timestamp of when the result was last seen. Previous results are retained for 90 days for comparison.
