How this service works
Six keyless pay-per-call tools for AI agents: OFAC SDN crypto-wallet screen, live DNS records lookup, SPF/DMARC/DKIM email-auth check, domain age/registrar (RDAP), email address MX verify and URL unshorten/redirect check. $0.01 per call: USDC on Base over x402, or USDC on Tempo over MPP. Also a remote MCP server at /mcp (x402).
Output
A JSON object containing the queried domain name, an 'exists' boolean, and a 'records' map keyed by DNS record type. Each record type entry includes a status (e.g. NOERROR), an 'authenticated' boolean (DNSSEC), and an array of answers with name, type, TTL, and data fields.
Example use cases
Verify domain email configuration
“Can you pull the TXT records for acme-corp.io? I want to see if they have SPF and DMARC records set up correctly.”
Find hosting IP for a domain
“What IP address does shopify.com resolve to? Give me the A records.”
Check nameservers before domain transfer
“Look up the NS records for mybusiness.net — I need to confirm which nameservers it's currently using before I initiate a transfer.”
Technical details
Endpoint
GEThttps://sdn-screen-x402.sdnscreen.workers.dev/v1/dns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a live, authoritative DNS record lookup without setting up API keys or accounts, and you are comfortable with micro-payment billing via x402/USDC on Base. It is especially useful for AI agent pipelines that need on-demand DNS resolution as part of domain validation, email deliverability checking, or infrastructure inspection workflows.
Side effects
- Domain does not exist in DNS — returns exists: false with empty records
- Invalid or malformed domain name — may return error or empty result
- Unsupported record type string — ignored or returns all records
- Upstream DNS resolver timeout — may return partial or error response
- Payment not completed via x402 — request rejected before DNS lookup is performed
