Example use cases
Email deliverability troubleshooting

Domain ownership verification
“Pull up all the TXT records for shopify.com — I'm checking for domain ownership verification tokens and SPF configuration.”
Technical details
Endpoint
GEThttps://dns-lookup.hsharmanov02.workers.dev/dns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, no-API-key DNS resolution via HTTPS, especially in serverless or agent contexts where setting up a full DNS library is impractical. It supports all common record types (A, AAAA, MX, TXT, NS, CNAME) and is ideal for one-off lookups or infrastructure checks. The x402 micropayment model makes it suitable for pay-per-use agent workflows without subscription overhead.
Side effects
- Domain does not exist or is not resolvable — returns an empty or error response
- Invalid record type string — may return an error or unexpected results
- Network or upstream DNS resolver failure — may return a timeout or 5xx error
- Payment failure via x402 — request blocked if USDC payment is not processed
- Malformed domain input — may return an error or null result
