How this service works
URL and content micro-tools for AI agents: parse URLs, probe HTTP status and security headers, extract text from HTML, text stats, and similarity. Pay with USDC via x402 — no API keys.
Output
Returns a JSON object with a success flag and details about the HTTP response including status code and security headers observed when making a GET request to the probed URL.
Example use cases
Broken link detection in content
“Check whether https://docs.mycompany.com/setup is actually returning a 200 or if it's broken — I want to know the status code and any security headers it sends back.”
Security header audit for a site
“Probe https://api.stripe.com with a GET request and tell me what security headers it has — I'm trying to see if they're using Content-Security-Policy and HSTS.”
Pre-flight check before scraping
“Before I try to extract content from https://news.ycombinator.com, can you check if it's reachable and what HTTP status it returns?”
Technical details
Endpoint
GEThttps://agent-link.annushka1190.workers.dev/v1/url/probeWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call HTTP probe without setting up API keys — ideal for checking link liveness, status codes, or security header presence as part of an automated agent workflow. Prefer it over full-page scraping tools when you only need response metadata, not content.
Side effects
- Target URL is unreachable or times out — may return an error or non-OK status
- Invalid or malformed URL input causes a 400-level error
- Target server blocks bot/automated requests, returning 403 or CAPTCHA
- Payment not completed via x402 protocol results in 402 response before the probe executes
- URL requires authentication, returning 401 or redirect to login
