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: result_status (PASS or FAIL indicating HTTP reachability), final_url (the fully resolved URL after any redirects), requested_url (the original URL submitted), and checked_at (ISO 8601 timestamp of when the check was performed).
Example use cases
Deployment go-live verification
“I just deployed a new version of my site to https://staging.mycompany.com — can you externally probe that URL and confirm it's live and returning a PASS status before I send it to the team?”
Redirect chain confirmation
“Check whether https://old.mysite.com actually redirects correctly to the new domain — I need to know the final URL it resolves to and whether it passes the HTTP reachability check.”
Third-party link health check
“Before I publish this newsletter, can you probe https://partner-offer.example.com and confirm it's publicly accessible and not broken?”
Technical details
Endpoint
POSThttps://td-agent-utility.abrdns.com/v1/probe-url?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an independent, third-party HTTP reachability check of a public URL — especially to confirm deployments are live, verify redirect chains, or validate that a URL is externally accessible from outside your own network. It returns a clean PASS/FAIL result with the final resolved URL, making it ideal for automated deployment pipelines or pre-send link validation.
Side effects
- URL is unreachable or returns an error status — result_status will be FAIL
- Invalid or malformed URL input causes request rejection
- Timeout if the target server takes too long to respond
- DNS resolution failure for the target domain
- Payment not completed via x402 V2 USDC results in no probe being executed
