How this service works

Quality-scored paid utility APIs for AI agents over x402 on Base USDC.

Output

A JSON object containing the HTTP status code, the originally requested URL, the final resolved URL after any redirects, an array of intermediate redirect URLs, and the content type of the final response.

Example use cases

Broken link checker for content pipeline

“Check whether https://oldsite.com/some-page is still reachable and tell me its HTTP status and whether it redirects somewhere else.”

Redirect chain audit for SEO

“I need to know if https://mycompany.com redirects to www or HTTPS — can you probe that URL and show me every redirect hop and where it finally lands?”

Domain liveness check before deployment

“Before I update our DNS, can you confirm that https://staging.myapp.io is returning a 200 and the content type looks like HTML?”

Technical details

Endpoint

POSThttps://agent-utility-network.frosty-sound-4560.workers.dev/v1/paid/domain-http-probe

When to prefer

Use this endpoint when you need to check HTTP reachability, resolve redirect chains, or verify the content type of a URL without downloading the full body. Prefer it over generic HTTP fetch tools when you specifically need the redirect path and final URL, or when you want a lightweight liveness check on a domain. It is ideal for link validation, SEO redirect audits, and pre-flight domain health checks.

Side effects

URL is unreachable or times out — may return a non-200 status or connection error
Malformed URL input (too short, invalid format) rejected by schema validation
Target URL returns an unusual or empty content type
Infinite redirect loop detected and aborted
DNS resolution failure for the target domain
