# Otto AI DNS Lookup

> Otto AI DNS Lookup is a paid API for AI agents from x402.ottoai.services, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Resolves DNS records for a domain, returning A, MX, NS, TXT, CNAME, AAAA, SOA records plus email security analysis (SPF, DKIM, DMARC).

## Facts

- Endpoint: GET https://x402.ottoai.services/dns-lookup
- Price: $0.001/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability otto-ai-dns-lookup-9efccd7a
```

Example prompt: Can you look up all the DNS records for stripe.com — I want to see the A records, MX servers, nameservers, and whether their SPF, DKIM, and DMARC email security is properly configured?

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call DNS lookup that also includes email security posture (SPF/DKIM/DMARC) rather than just raw record data. Ideal for agents performing domain reconnaissance, email infrastructure validation, or security audits. Priced at $0.001 USDC per call via x402, making it cost-effective for high-frequency lookups.

## Known failure modes

- Domain does not exist or fails to resolve — resolves: false in response
- Invalid domain format supplied — likely a 4xx or validation error
- Network/upstream DNS resolver failure — may return degraded:true in meta
- Rate limit or payment failure — 402 payment required or 429 response
- Timeout on slow-resolving domains

## How this service works

Resolve any domain in one call: A/AAAA, MX, NS, CNAME, SOA and TXT records, plus parsed email-auth posture — SPF policy, DMARC policy, and detected DKIM selectors. A drop-in nslookup/dig replacement for agents, resolved over DNS-over-HTTPS (DoH) with redundant resolvers and automatic failover. Keyless, pay-per-call, structured JSON.

## Output

Returns a structured JSON object with the domain's resolution status, A/AAAA/MX/NS/TXT/CNAME/SOA records, and an email security breakdown including SPF policy and record, DKIM selectors found, and DMARC policy and record. Also includes metadata with freshness timestamp and staleness info.
