How this service works
Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.
Output
Returns a JSON object containing the queried hostname and arrays of DNS record values for each type: A (IPv4 addresses), AAAA (IPv6 addresses), MX (mail exchange), TXT (text records), and CNAME (canonical name aliases). Empty arrays are returned for record types with no results.
Example use cases
Email deliverability check for domain
“Can you pull the MX and TXT records for sendgrid.com so I can verify its mail server configuration?”
IP address resolution for monitoring
“What IP address does stripe.com resolve to right now? Fetch the A records for me.”
Domain verification before deployment
“Look up the DNS records for myapp.example.com — I need to confirm the CNAME is pointing to the right place before I go live.”
Technical details
Endpoint
GEThttps://volkov.evgeny.m2.fvds.ru/pay/dns?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a pay-per-use, no-subscription DNS lookup accessible programmatically via the x402 micropayment protocol on Base. It is well-suited for agents that need occasional DNS resolution without managing API keys, paying $0.002 USDC per call. Prefer alternatives like Google DNS or Cloudflare DNS APIs if you need high-volume, free, or SLA-backed resolution.
Side effects
- Invalid or non-existent hostname returns empty record arrays
- Missing required 'host' query parameter may return an error or empty result
- Network timeouts if upstream DNS resolver is slow
- Payment failure if USDC balance is insufficient on Base
- Rate limiting or server unavailability on the underlying VPS
