# Halowerk Agent Readiness List Structure Audit

> Halowerk Agent Readiness List Structure Audit is a paid API for AI agents from agentreadiness.halowerk.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-14).

Passively audits a public URL's list structure (HTML lists, navigation menus, etc.) for agent-readability, returning an observation, threshold verdict, evidence source, limitations, and a recommended action.

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 halowerk-agent-readiness-list-structure-audit-1399c271 -d '<json body>'
```

Example prompt: Can you audit the list structure on https://example.com to see if it meets AI agent-readability standards — I want to know the verdict, what evidence was found, and what action I should take?

## When to prefer this

Use this endpoint when you need a passive, read-only verdict on whether a specific website's HTML list structure (lists, menus, navigation) meets AI agent-readability criteria. Prefer it over generic accessibility checkers when the goal is specifically AI/LLM agent compatibility. It is part of the Halowerk agent-readiness suite and pairs well with sibling audits (header semantics, article boundaries, machine-readable titles) for a full site assessment.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — audit cannot fetch evidence
- Target domain does not resolve — normalization to HTTPS fails
- Page has no list elements — observation returns empty with a no-list-structure verdict
- Rate limiting or bot protection on target blocks passive fetch — evidence source unavailable
- Baseline schema mismatch if a prior snapshot is incompatible with current endpoint version

## How this service works

List structure 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 audit result including: the observation (what was found on the target page), the threshold used to evaluate it, a pass/fail verdict, the exact evidence source (URL/element), known limitations of the passive check, and a mode-specific recommended action. No login, form submission, or exploit is performed.
