How this service works
Paid HTTP endpoints for AI agents, settled in USDC on Base via the x402 protocol. No account, no API key — pay per call.
Output
Returns a JSON object indicating: whether the URL returns a 2xx HTTP status, whether AI bots (GPTBot, ClaudeBot, and wildcards) are permitted by robots.txt, whether the page is behind a paywall, whether JavaScript is required to render the page, whether the page is blocked, and if blocked, the reason.
Example use cases
Bot access check before scraping
“Before you scrape https://www.bloomberg.com/news/articles/2024-03-01/some-article, can you preflight it to see whether AI bots like GPTBot or ClaudeBot are allowed and if the page is behind a paywall?”
JS rendering requirement detection
“I want to extract content from https://app.somesite.com/dashboard — can you preflight that URL first to tell me if it requires JavaScript to render, or if it's likely to return a blank page?”
Confirming open access before paid fetch
“Before spending credits to fetch https://techcrunch.com/2024/05/10/openai-news/, can you do a quick preflight to confirm it's not paywalled and that bots are actually allowed in the robots.txt?”
Technical details
Endpoint
GEThttps://api.neuroterminal.xyz/v1/fetch-preflightWhen to prefer
Use this endpoint when you need a lightweight, cheap ($0.01) pre-check before committing to a more expensive or complex web fetch operation. It is ideal for filtering out paywalled, bot-blocked, or JS-heavy URLs before sending them to a full rendering or scraping pipeline. Prefer this over full-fetch endpoints when you only need access metadata rather than page content.
Side effects
- URL is unreachable or returns a network error — blocked flag may be true with a reason
- Malformed or missing URL parameter — returns a validation error
- robots.txt is absent or unparseable — wildcard permissions may default to true
- JavaScript detection may produce false positives for complex SPAs
- Paywall detection may not catch soft paywalls or metered access
