## How to call it through Zero

```sh
zero fetch --capability www-vs-apex-check-watch-139958aa
```

Example prompt: Keep an eye on whether the www vs apex redirect check for my domain has changed since the last time you checked — tell me what's different and what the current result is.

## When to prefer this

Choose this endpoint when you need to detect changes in www vs apex domain redirect/DNS behavior over time on a polling schedule, rather than just fetching the current state once. It is ideal for automated monitoring pipelines, post-deployment verification, and SEO audits where you need a diff of exactly what changed and when, without maintaining your own state storage.

## Known failure modes

- Domain not provided or malformed — returns validation error
- First-time call for a domain has no previous result to compare against — returns current result with changed=false or null baseline
- Domain unreachable or DNS resolution failure — check result may be an error state
- State older than 90 days has been purged — treated as a fresh baseline
- Payment failure or insufficient USDC balance — request rejected before check runs

## How this service works

Change watch for www apex check: 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 www vs apex check changes. $0.01 per check.

## Output

Returns the current www-vs-apex check result for the domain, a boolean indicating whether it 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. State is retained for 90 days per domain.
