# ClaudeBot Access Decision

> ClaudeBot Access 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).

Passively inspects a public URL to determine whether ClaudeBot (Anthropic's crawler) can access and read it, returning an observation, verdict, evidence source, and recommended action.

## Facts

- Endpoint: POST https://agentreadiness.halowerk.com/v1/claudebot-access-decision?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-14

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 claudebot-access-decision-0469bf10 -d '<json body>'
```

Example prompt: Check whether ClaudeBot is allowed to access https://example.com — I need to know the verdict, what evidence was found, and what action I should take.

## When to prefer this

Use this endpoint specifically when you need to determine if Anthropic's ClaudeBot crawler is permitted to access a given public URL or domain. Prefer it over generic crawler audits when the specific concern is Claude AI indexability. It is a passive read-only check with no side effects, making it safe to call repeatedly for monitoring. Choose sibling endpoints for other crawlers (e.g., generic crawler access audit) or for different agent-readiness checks (e.g., llms.txt availability).

## Known failure modes

- Target URL unreachable or returns non-200 status — verdict may be indeterminate
- robots.txt absent — may default to open access assumption
- Rate limiting on target may prevent evidence retrieval
- Ambiguous robots.txt rules may produce uncertain verdict
- Malformed or non-HTTP URL rejected with validation error

## How this service works

ClaudeBot access 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 result containing: the raw observation (what was found at the target), the evaluated threshold/criterion, a binary or graded verdict on ClaudeBot access, the exact evidence source used, any limitations of the passive check, and a mode-specific recommended action — all without performing any login, exploit, form submission, or load test.
