How this service works
Web search built for AI agents. Search the live web, pull recent news, and read any page as clean markdown — pay per call, free tier to start.
Output
Returns resolved DNS records for the queried hostname and record type — e.g. IP addresses for A records, mail server hostnames and priorities for MX records, string values for TXT records, or canonical names for CNAME records.
Example use cases
Example prompt
“What are the MX records for github.com? I want to see which mail servers handle their email.”
Technical details
Endpoint
GEThttps://superhighway.walls.sh/dns?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to programmatically resolve DNS records for any hostname without standing up its own DNS resolver. Ideal for network diagnostics, domain validation, email deliverability checks, or infrastructure reconnaissance tasks within an agent workflow. Pay-per-call pricing makes it cost-effective for low-to-moderate volume lookups.
Side effects
- Host not found or NXDOMAIN — domain does not exist
- Invalid record type specified — returns error or defaults to A
- Timeout resolving DNS — upstream resolver unavailable
- Malformed hostname input — error response
- Rate limit exceeded — HTTP 429
