How this service works
Agent-visibility check: does an AI crawler (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot) actually see your site? ENTRY pack: 1 check for $2 ($2/check). Same service, best rate $1.25/check at https://402registry.com/buy/four. Ladder: 1/$2, 2/$3, 4/$5. All packs: https://402registry.com/.well-known/402registry.json. A passing check earns a dated badge and a registry listing. No account, no card, no human.
Output
Returns a pass or fail result indicating whether the specified site is visible to major AI crawlers (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot). On a passing check, the agent receives a dated compliance badge and a public registry listing confirming crawler accessibility.
Example use cases
Verify AI crawler access before launch
“Before we launch our new blog, can you check if AI crawlers like GPTBot and ClaudeBot can actually see it at myblog.com, and get us a registry badge if it passes?”
Audit competitor AI visibility
“Can you run an AI crawler visibility check on competitor-site.com to see whether GPTBot and PerplexityBot can index it?”
Confirm AI bot access after robots.txt change
“We just updated our robots.txt — can you verify that AI crawlers like ClaudeBot and GPTBot can still access our site at mycompany.com and get us a new dated badge?”
Technical details
Endpoint
GEThttps://402registry.com/buy/one?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, one-off AI crawler visibility check for a website and want a dated badge and public registry listing as proof of compliance. It is ideal for site owners who have just launched or updated their robots.txt and need immediate verification without an account or subscription. At $2/check (ENTRY pack), it is best suited for occasional checks; for frequent or bulk checks, higher-tier packs at 402registry.com offer better per-check rates.
Side effects
- Site is blocking AI crawlers — returns a fail result with no badge issued
- Invalid or unreachable URL — endpoint may return an error or non-200 status
- Payment not completed — check is not executed without the $2 USDC payment
- Robots.txt disallows crawling — check may fail even if the site is live
- Rate limiting or transient network issues causing the check to time out
