# WAF Detect Watch

> WAF 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).

Monitors a domain's web application firewall (WAF) detection status over time, alerting when the WAF configuration changes between polling calls.

## Facts

- Endpoint: GET https://intel.rallylive.ca/watch/site/waf
- Price: $0.02/call
- Payment: x402
- Status: unknown

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 waf-detect-watch-49da9fc4
```

Example prompt: Keep an eye on example.com and let me know if its web application firewall detection changes from what you last recorded — I want to know exactly which fields changed and what they were before and after.

## When to prefer this

Choose this endpoint when you need scheduled, stateful change detection for WAF presence rather than a one-shot WAF lookup. It is ideal for security monitoring pipelines, CI/CD security gates, or competitive intelligence workflows where knowing *when* something changed (not just what it currently is) is critical. Prefer it over a plain WAF detection endpoint when you want diffs and change history rather than just the current state.

## Known failure modes

- Domain not reachable or invalid URL returns an error or empty detection result
- First call for a domain has no previous state to compare against, so 'changed' may be false or undefined
- Rate limiting or payment failure ($0.01 per check via x402) blocks the request
- Domain behind a CDN may intermittently show different WAF signatures causing false positives
- Stored comparison state expires after 90 days, resetting the change baseline

## How this service works

Change watch for waf detect: 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 web application firewall detection changes. $0.01 per check.

## Output

Returns the current WAF detection answer, a boolean 'changed' flag indicating whether the result differs from the previous call for the same domain (stored for 90 days), a diff of exactly which fields changed with their before and after values, and the timestamp of when the state was last seen.
