How this service works
Pay-per-call data & tool APIs
Output
A JSON object containing: whether llms.txt and llms-full.txt exist and their byte sizes, a per-crawler verdict (allowed/blocked) for major AI bots including GPTBot, ClaudeBot, ChatGPT-User, Amazonbot, Bytespider, PerplexityBot, Google-Extended, CCBot, and anthropic-ai, a human-readable summary, the canonical domain URL, and the timestamp of when the data was scraped. Also includes run time in milliseconds and payment settlement confirmation.
Example use cases
Pre-scrape AI crawler policy check
“Before I try to crawl techcrunch.com with my AI agent, can you check whether it has an llms.txt and whether it blocks GPTBot or ClaudeBot?”
Competitor content access audit
“I want to know if our competitor's site salesforce.com blocks AI crawlers like Amazonbot, PerplexityBot, and Google-Extended — can you run an llms.txt audit on it?”
Research dataset sourcing validation
“I'm building a training dataset and need to know if wikipedia.org allows CCBot and Bytespider — check its llms.txt and robots.txt AI crawler rules for me.”
Technical details
Endpoint
POSThttps://api.timzinin.com/api/llms-txt-auditorWhen to prefer
Use this endpoint when you need to quickly determine AI crawler access policy for a specific domain without manually fetching and parsing robots.txt or llms.txt yourself. Ideal for agents that need to validate whether a site permits AI scraping before attempting it, for dataset curation pipelines that must respect publisher permissions, or for monitoring whether a domain's AI crawler policy has changed. At $0.01 per call it is cost-effective for per-domain spot checks.
Side effects
- Domain not found or unreachable — found:false with empty crawler data
- Network timeout fetching robots.txt or llms.txt — may return partial or stale results
- Invalid domain format in input — likely returns an error or empty result
- Domain exists but has no robots.txt and no llms.txt — all crawlers reported as allowed by default
- Rate limiting or firewall on target domain may cause scrape failure
