How this service works
Footer semantics audit fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.
Output
Returns a structured report containing: the observed footer state, the evaluated criterion, a pass/fail verdict against a defined threshold, the exact public evidence source used, any limitations of the passive check, and a mode-specific recommended action — no login, injection, or intrusive testing is performed.
Example use cases
Pre-launch agent readiness check
“Before we launch our new site at mybrand.com, can you audit the footer semantics and tell me if it'll be readable by AI agents — include the verdict and any recommended fixes?”
Competitor footer benchmarking
“Run a footer semantics audit on competitor-site.com and a separate one on our site mybrand.com so I can compare how our footer stacks up against theirs for agent readiness.”
Ongoing footer compliance monitoring
“Check the footer semantics on our blog at blog.acme.com against last week's baseline snapshot and tell me if anything has changed or regressed since then.”
Technical details
Endpoint
POSThttps://agentreadiness.halowerk.com/v1/footer-semantics-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a passive, non-invasive semantic audit of a public website's footer for AI agent readiness or discoverability signals. It is ideal for pre-launch compliance checks, ongoing monitoring pipelines, or benchmarking against a baseline or comparison URL. Prefer it over general SEO crawlers when the specific concern is footer-level semantic structure as evaluated against agent-readiness criteria rather than broad site health.
Side effects
- Target URL is unreachable or returns non-200 status — audit cannot proceed
- Target requires authentication — passive check cannot access gated content
- Footer content is rendered only via JavaScript and not available in static HTML — evidence may be incomplete
- Malformed or overly short target URL fails schema validation (minLength:3)
- Rate limiting or blocking by the target server prevents fetching
