How this service works
Pay-per-call B2B sales lead and procurement intelligence plus Base wallet data for agents. Search EU tenders/RFPs or inspect a Base wallet. Payments use x402 USDC on Base.
Output
Returns a JSON object containing the queried domain name, a list of DNS records each with type, name, value, and TTL, the total record count, the requested record types, and a timestamp of when the lookup was generated.
Example use cases
Check domain IP resolution
“What IP address does stripe.com resolve to? Look up the A records for me.”
Verify email sender DNS records
“Can you pull the MX and TXT records for acmecorp.com so I can check their SPF and mail server configuration?”
Audit domain DNS setup
“Look up all DNS records for my domain startup.io — I need to see A, CNAME, NS, and TXT records to audit the setup.”
Technical details
Endpoint
GEThttps://eu-tender-x402-v2-production.up.railway.app/api/dns-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs programmatic, pay-per-call DNS record resolution without setting up a dedicated DNS client library. It is ideal for lightweight, one-off lookups in agentic workflows where DNS data is needed alongside other Revenue Swarm intelligence (EU tenders, wallet data). At $0.001 per call it is cost-effective for infrequent or ad-hoc resolution needs.
Side effects
- Domain not found or does not exist — empty records array returned
- Invalid domain format — request rejected with validation error
- Unsupported DNS record type requested — may return empty or error
- Payment failure via x402 — request blocked if USDC payment not processed
- Network timeout if upstream DNS resolver is unreachable
