How this service works
Machine-readable settlement service
Output
A JSON object containing the DNS A record resolution result for the provided hostname, including the resolved IPv4 address(es). The response schema is open-ended (additionalProperties: true), so additional DNS metadata may be included.
Example use cases
Verify server IP before deployment
“Before I deploy, can you resolve the A record for staging.myapp.io and confirm what IPv4 address it points to?”
Debug misconfigured domain routing
“I think my domain is pointing to the wrong server — can you do a DNS A lookup for shop.mybrand.com and tell me the IP it resolves to?”
Monitor third-party API hostname
“Can you check what IP address api.thirdpartyservice.com currently resolves to? I want to make sure it hasn't changed.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/network/dns.a--dns-lookupWhen to prefer
Use this endpoint when you need a quick, programmatic DNS A record lookup within an agent workflow that already handles x402 micropayments. It is well-suited for lightweight infrastructure checks, pre-deployment validations, or enriching data pipelines with IP resolution, especially when you want a pay-per-call model rather than managing a DNS SDK or credentials.
Side effects
- Invalid or malformed hostname input returns an error
- Non-existent domain (NXDOMAIN) results in resolution failure
- Network timeout if DNS upstream is unreachable
- Missing required 'input' field returns a validation error
- Payment failure (insufficient USDC) blocks the request via x402 protocol
