## What it does

Live DNS records for a domain via DNS-over-HTTPS \(1.1.1.1\): A, AAAA, CNAME, MX, NS, TXT, CAA, SOA, or type=ALL for all of them plus parsed SPF and DMARC policy. Returns rcode \(NOERROR/NXDOMAIN\), records with TTL, DNSSEC AD flag. Returns the full, untrimmed result as JSON. A free public MCP at https\://orbit-web.orbit-builder.workers.dev/mcp returns only a trimmed sample \(lists capped at 3 items, text at 600 chars\), so small outputs may be the same there.

## How to buy

```text
PAID ($0.001/call): call_service({ id: "svc_1d896561-7540-4581-a14f-ffd0f9a94501", args }) — the 402 lists ONE x402 payment = the FULL price straight to the seller (FiatDock takes 0% of this listing's calls right now); the fiatdock-mcp npm package (AGENT_PRIVATE_KEY) pays it automatically. This remote /mcp returns the 402 challenge. You are charged only if the seller actually answers. To learn what to put in arguments, call get_service({ id: "svc_1d896561-7540-4581-a14f-ffd0f9a94501", includeSchemas: true }) first — it returns toolSchemas (argument names and types). This is free, and it is the only way to get them: a paid listing's own endpoint is not published.
