## 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-access-check-x402-domain-url-accessibility-verifier-1a394c95
```

Example prompt: Can you check whether openai.com is accessible and whether an AI agent can reach it — just pass the bare domain to The Stall's agent access check?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call check on whether a specific domain or URL is accessible without needing API keys or accounts. Ideal for agents that need to verify web resource reachability before attempting to fetch or interact with content, especially in x402 micropayment workflows on Base mainnet.

## Known failure modes

- Missing required 'url' query parameter — returns validation error
- Invalid or malformed URL/domain input — may return error or negative access status
- Domain does not exist or DNS fails — returns inaccessible status
- Network timeout reaching the target domain — may return timeout error
- Payment not completed via x402 — returns 402 Payment Required

## How this service works

Checks whether a website is accessible and agent-friendly. Fetches robots.txt, .well-known/ai.txt, and sitemap.xml; inspects HTTP headers (CORS, CSP, rate-limit); and returns a readiness verdict. Useful for agents that need to decide whether to scrape, crawl, or interact with a domain before committing to a workflow. Returns allowed/blocked status, disallowed paths, crawl delay, AI-specific rules, and sitemap URL if present.

## Output

Returns an access status result indicating whether the given domain or URL is reachable and accessible to AI agents, likely including an access flag and reachability indicators.
