How this service works
Independent public URL, HTTP, DNS, TLS, browser screenshot and deployment verification for AI agents. Pay per completed job with x402 V2 USDC on Base.
Output
A JSON object containing the requested URL, the final URL after following any redirects, the UTC timestamp of the check, and a result_status of PASS or FAIL indicating whether the URL was publicly reachable.
Example use cases
Post-deployment liveness check
“I just deployed my new app to https://app.myproject.io — can you probe that URL from the outside and confirm it's actually returning a passing status before I announce it?”
Redirect chain verification
“Check if https://myoldsite.com is still correctly redirecting to https://www.mynewsite.com — I want to know the final URL it resolves to and whether the probe passes.”
Third-party service reachability
“Can you verify that https://api.partner-service.com/health is publicly reachable right now? I need an independent check to confirm it's not just down on my end.”
Technical details
Endpoint
POSThttps://td-agent-utility.duckdns.org/v1/probe-url?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need an independent, external HTTP reachability check that is not subject to local network conditions or the agent's own connectivity — ideal for post-deployment verification, confirming public accessibility of APIs or websites, or validating redirect behavior. Prefer over self-hosted monitoring scripts when you need a neutral third-party perspective on liveness.
Side effects
- URL is unreachable or returns a non-success HTTP status, resulting in result_status: FAIL
- Malformed or invalid URL input causes a request error
- Target server times out before responding
- DNS resolution failure for the given hostname
- Payment authorization failure via x402 before the probe executes
