How this service works
A record of sandbox.<domain>: looks up the sandbox host under the domain you give (A via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like sandbox without enumerating subdomains. $0.01 per lookup.
Output
Returns whether sandbox.<domain> has an A record, the resolved IP address(es), and the TTL value, based on a Cloudflare DoH query.
Example use cases
Verify sandbox environment is live
“Does sandbox.stripe.com actually exist in DNS? I want to know if it resolves to an IP and what the TTL is.”
Pre-integration sandbox reachability check
“Before I configure my integration, can you check whether sandbox.mypaymentprovider.com has a valid A record so I know the sandbox environment is up?”
Domain audit for sandbox subdomain
“I'm auditing example.com's DNS setup — can you check if the sandbox subdomain exists and report back the A record and TTL?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/sandbox/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted check for the sandbox subdomain on a given domain without enumerating all subdomains. It's ideal for pre-flight checks before API integrations, environment audits, or confirming sandbox infrastructure is live. Prefer this over general DNS tools when you specifically care about the sandbox host and want A record resolution via Cloudflare DoH.
Side effects

- sandbox subdomain not configured — query returns empty answer section
- Invalid domain format provided — malformed request error
