How this service works
Fetch a public HTTP(S) URL and return status, final URL, headers summary, and redirect chain. This deterministic endpoint does not call an upstream model. Pay up to $0.001 per request with x402 USDC on Base. Public paid calls are limited to 1500 input characters and 128 output tokens.
Output
Returns a JSON object with an 'ok' boolean, the tool name ('httpStatus'), a summary of HTTP status and redirect details, and a fetchedAt timestamp indicating when the check was performed.
Example use cases
Monitor link health in content
“I'm publishing an article with a bunch of external links tomorrow. Can you quickly check all these URLs to make sure they're actually live and not returning errors or broken redirects? Here's my list: https://example.com, https://another-site.org, https://third-link.net”
Validate URLs before sending
“Before I send out this newsletter with these three resource links to our subscribers, I need to verify they're all up and working properly. Can you check the status of each link and let me know if any of them are down or redirecting unexpectedly?”
Detect redirected checkout pages
“I'm trying to debug why some users report confusion when they click our payment links. Can you check what's happening with https://checkout.example.com – does it return a 200, is it redirecting somewhere else, and what's the actual final URL they end up on?”
Technical details
Endpoint
GEThttps://gpt55.558686.xyz/v1/tools/http-statusWhen to prefer
