How this service works
Advanced micro-tools for AI agents: cryptographic randomness, text analysis, math helpers, date arithmetic, web metadata, and IP intelligence. All under $0.01 per request, paid in USDC via x402.
Output
Returns a JSON object with ok:true and the full set of HTTP response headers returned by the target URL, including header names and their values as key-value pairs.
Example use cases
Security header audit for a domain
“Check what security-related HTTP headers https://mybusiness.com is returning — I want to know if they have HSTS, X-Frame-Options, and Content-Security-Policy set.”
Detect CDN or server technology
“Fetch the response headers for https://shopify.com and tell me what CDN and server software they're using based on the headers.”
Debug CORS configuration
“Pull the HTTP headers from https://api.myservice.io/data so I can see if it's returning the right CORS headers like Access-Control-Allow-Origin.”
Technical details
Endpoint
GEThttps://agent-micro.annushka1190.workers.dev/v1/web/headersWhen to prefer
Choose this endpoint when you need lightweight, low-cost ($0.004 USDC) programmatic access to the raw HTTP headers of any public URL without fetching the full page body. Ideal for agents performing security audits, CDN detection, cache policy inspection, or CORS debugging without needing full page content.
Side effects
- Invalid or malformed URL returns an error response
- Target URL is unreachable or times out
- URL requires authentication and returns 401/403 without headers
- Non-HTTP/HTTPS schemes are not supported
- Rate limiting or firewall on the target server blocks the request
