> agent-services x402 web tools – robots.txt / sitemap lookup is a paid API for AI agents from 49112-hjhjtioxvirqvcvo.splox.app, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-02).

Fetches and parses a website's robots.txt file, returning crawl rules, allowed/disallowed paths, sitemap URLs, crawl delay, and existence status for a given site URL.

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-services-x402-web-tools-robots-txt-sitemap-lookup-6a2583ef
```

Example prompt: Can you check the robots.txt for https://example.com and tell me whether crawling is allowed, what the crawl delay is, and list any sitemap URLs it references?

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically check a website's crawl permissions, discover sitemap URLs, or verify bot policies before crawling — especially when you want a structured, parsed result rather than raw text. It is paid per-call via x402/USDC on Base, making it suitable for lightweight, on-demand checks without a subscription.

## Known failure modes

- Site does not have a robots.txt (exists=false, empty rules)
- Target site is unreachable or times out (error field populated)
- Site returns non-200 status for robots.txt (status field reflects actual HTTP code)
- Malformed robots.txt that cannot be parsed (rules array may be empty or partial)
- Payment failure over x402 protocol preventing the call from being processed

## How this service works

Paid per-call web tools for AI agents: DNS, TLS, robots.txt, hashing, JavaScript rendering and screenshots. Payment over x402 (USDC on Base).

## Output

Returns a JSON object containing the canonical robots.txt URL, whether the file exists, its HTTP status code, an array of parsed crawl rules (with user-agent, allow/disallow paths), discovered sitemap URLs, crawl delay (if specified), and any error or note messages.
