How this service works
Inspect URL reachability, status, latency, and key headers for $0.001 USDC. Call when you need a cheap uptime preflight before paying a heavier fetch—not a full page extract and not a crawl. Returns status and timing via x402. No API key, no subscription.
Output
Returns whether the URL is reachable, the HTTP status code, response latency in milliseconds, and key HTTP response headers observed during the probe.
Example use cases
Pre-deploy endpoint reachability check
“Before I deploy, can you verify that https://staging.myapp.com/api/status is actually responding with a 200 and tell me how fast it replies?”
Diagnose broken third-party integration
“Our integration with https://partner-api.acme.com/webhook keeps failing — can you check if that URL is reachable and what HTTP status and headers it's returning?”
Monitor uptime for a public URL
“I want to know if https://status.myservice.io is up right now — check its reachability, latency, and status code and tell me the results.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/url-health?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, lightweight probe of a single URL's availability, status code, latency, and headers without needing full content retrieval or deep inspection. Ideal for pre-flight checks, uptime verification, or diagnosing connectivity issues from an agent context.
Side effects
- URL is unreachable or DNS does not resolve — returns error with reachability failure indicator
- Target URL times out — returns timeout error with no status or headers
- Invalid or malformed URL input — returns validation error
- Target server returns unexpected or non-standard HTTP response
