How this service works
Fetches a public web page and returns its title, meta description, outbound links and readable plain text as JSON.
Output
Returns a JSON object containing the final resolved URL, HTTP status code, response time in milliseconds, and a map of all HTTP response headers (e.g. content-type, cache-control, set-cookie, server, etc.).
Example use cases
Verify security headers on a site
“Check what HTTP security headers https://mycompany.com is returning — I want to know if it has things like Strict-Transport-Security, X-Frame-Options, or Content-Security-Policy set.”
Inspect CORS policy of an API
“Fetch the headers for https://api.openweathermap.org/data/2.5/weather and tell me what CORS-related headers it returns, like Access-Control-Allow-Origin.”
Detect redirect and final URL
“Can you probe https://bit.ly/3xyz and tell me the HTTP status code and what URL it ultimately resolves to based on the response headers?”
Technical details
Endpoint
GEThttps://automatom.matt-d59.workers.dev/headers?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to inspect the raw HTTP headers returned by a public URL — e.g. to check security posture, content-type, caching policy, CORS settings, or redirect behavior — without needing to parse the page body. It is distinct from full-page scraping endpoints on the same service that return title, links, and readable text.
Side effects
- URL is unreachable or times out — likely returns an error object or non-200 status
- Invalid or malformed URL provided — may return a 400-level error
- Private or localhost URLs may be blocked by the worker sandbox
- Some sites may block automated requests, resulting in 403 or empty header sets
- SSL/TLS errors on the target site may prevent fetching
