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 original requested URL, the final URL after any redirects, the ISO 8601 timestamp of when the check was performed, and a result_status string (e.g. 'PASS' or 'FAIL') indicating whether the page was successfully reached.
Example use cases
Deployment smoke test after release
“I just pushed a new version of my app to production at https://app.mycompany.com — can you independently verify it's publicly reachable and tell me the final URL and whether it passes?”
Redirect chain validation after domain migration
“We migrated our site and set up a redirect from https://old.mysite.com to https://new.mysite.com — can you verify that URL is reachable and confirm what the final resolved URL actually is?”
Pre-campaign landing page live check
“Before we launch the email campaign, can you verify that the landing page at https://promo.brand.com/summer-sale is live and returning a PASS — I need an independent confirmation it's not down.”
Technical details
Endpoint
POSThttps://td-agent-utility.duckdns.org/v1/verify-page?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an independent, third-party, deterministic check that a specific public web page is live and reachable — especially for post-deployment verification, redirect validation, or pre-launch confirmation. Prefer it over self-monitoring (which can't detect issues visible only from outside your network) and over simple ping tools (which don't follow redirects or render browser-level responses). The pay-per-use x402 USDC model means no subscription required.
Side effects
- URL is unreachable or times out — result_status returns FAIL
- Invalid or malformed URL input — likely 4xx error response
- Page exists but returns an HTTP error code (e.g. 404, 500) — FAIL status
- DNS resolution failure for the domain — FAIL status
- Payment not completed via x402 — request rejected before verification runs
