# Agent-Readable Article Boundaries Decision

> Agent-Readable Article Boundaries Decision 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).

Fetches live public evidence from a target URL and evaluates whether the page has agent-readable article boundaries, returning an observation, threshold, verdict, evidence source, limitations, and 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 agent-readable-article-boundaries-decision-b4cb53b4 -d '<json body>'
```

Example prompt: Check whether the article at https://example.com/blog/my-post has clear, agent-readable article boundaries — I want to know if AI crawlers can detect where the article starts and ends, and what I'd need to fix if not.

## When to prefer this

Use this endpoint when you need a fast, passive, verdict-based check specifically on article boundary semantics (e.g. <article> tags, semantic section delineation) for a single public URL. Prefer this over general SEO audits or full site crawlers when the goal is agent-readiness compliance for AI bots. Choose the sibling 'repair plan' endpoint if you want actionable remediation steps instead of just a verdict.

## Known failure modes

- Target URL is unreachable or returns non-200 status — evaluation cannot proceed
- Target URL is behind authentication or a paywall — passive check cannot access content
- Malformed or non-HTTP(S) URL supplied — request rejected with validation error
- Target page has no article-boundary-relevant markup — observation returns inconclusive or absent evidence
- Rate limiting or timeout on the target server during fetch — incomplete evidence returned

## How this service works

Agent-readable article boundaries decision 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: an observation of what was found on the target page, the threshold criterion being evaluated, a pass/fail verdict, the exact evidence source (e.g. HTML element, meta tag), any limitations of the passive check, and a recommended action for the specific mode — all derived from live, passively fetched public page content.
