How this service works
Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.
Output
Returns a JSON object containing the queried domain name, the DNS record type (e.g. 'A'), and an array of resolved records (e.g. IPv4 addresses). Example: {"name": "example.com", "type": "A", "records": ["93.184.216.34"]}.
Example use cases
Verify domain IP before deployment
“Before I deploy, can you check what IP address myapp.example.com currently resolves to? I want to make sure the DNS is pointing to the right place.”
Investigate suspicious domain activity
“I got a phishing email from support@secure-login-alert.net — can you look up the IP address that domain resolves to so I can investigate where it's hosted?”
Automate infrastructure health check
“As part of my monitoring workflow, resolve the IP for api.myservice.io so I can confirm it still matches our expected server address.”
Technical details
Endpoint
GEThttps://api.polyform.org/v1/dns/lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, account-free, API-key-free DNS A-record resolution capability and are comfortable making micropayments in USDC on Base via the x402 protocol. Ideal for AI agents that need to resolve hostnames on-demand without setting up OAuth or managing API credentials. Best for low-volume, pay-per-use DNS lookups rather than high-frequency bulk resolution.
Side effects
- Domain does not exist (NXDOMAIN) — may return empty records or an error response
- Network timeout if DNS resolution takes too long
- Invalid domain name format — malformed input may cause a 4xx error
- Payment failure or insufficient USDC balance — request blocked before DNS query is performed
- Rate limiting if micropayment is not processed correctly
