## How to call it through Zero

```sh
zero fetch --capability dns-soa-records-lookup-45d71026
```

Example prompt: Can you look up the SOA DNS record for example.com so I can see its primary nameserver and zone serial number?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call DNS SOA lookups without signup or API key management. Ideal for AI agents performing automated DNS audits, zone verification, or infrastructure checks where micro-payment via USDC on Base is acceptable and no persistent account relationship is desired.

## Known failure modes

- Domain does not exist (NXDOMAIN) — returns error indicating no SOA record found
- Network timeout resolving DNS query
- Invalid domain format in input — returns validation error
- Domain has no SOA record configured — empty or null result
- Payment failure via x402 — 402 response before data is returned

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object containing the SOA record fields for the queried domain, including primary nameserver (MNAME), responsible party email (RNAME), serial number, refresh interval, retry interval, expire time, and minimum TTL.
