Output

Returns a JSON object containing the page URL, whether llms.txt exists, a list of named AI crawlers (e.g. GPTBot, ChatGPT-User, OAI-SearchBot) with their allowed/blocked status, robots.txt existence, opt-out flags (noai, noimageai, metaRobots, xRobotsTag), the data source (robots.txt + static HTML), and a timestamp of when the check was performed.

Example use cases

Pre-crawl AI permission check

“Before I scrape https://openai.com/ with my AI agent, can you check whether it allows GPTBot and OAI-SearchBot in its robots.txt and whether it has an llms.txt file?”

AI training data opt-out audit

“I want to know if https://nytimes.com/ has opted out of AI image training or AI crawling — check its robots.txt, meta robots tags, and X-Robots-Tag for any AI opt-out signals.”

Dataset source compliance verification

“I'm building a dataset from web pages and need to confirm https://huggingface.co/ permits AI crawlers — can you check its crawler policy including llms.txt and any noai or noimageai directives?”

Technical details

Endpoint

GEThttps://api.sitecheck-api.workers.dev/api/ai-crawlers?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need to programmatically verify whether a specific webpage or domain permits AI crawlers before scraping, indexing, or training on its content. It is the right choice when you need granular per-bot permission data (GPTBot, ChatGPT-User, OAI-SearchBot) and want to check both robots.txt and llms.txt in one call. Prefer it over generic robots.txt parsers when you specifically care about AI crawler opt-out signals (noai, noimageai) and meta/header-level directives.

Side effects

URL not reachable or returns non-200 — robots.txt may be assumed absent
Malformed URL input causes validation error
Site uses JavaScript-rendered robots directives that static HTML parsing misses (no JS execution)
robots.txt exists but is malformed or uses non-standard syntax — partial parsing may occur
Rate limits or network timeouts on the target server may cause incomplete results
