# DNS SOA Record Lookup

> DNS SOA Record Lookup is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Fetches the DNS Start of Authority (SOA) record for a domain, returning primary nameserver, admin contact, serial number, and all zone timers as structured JSON.

## Facts

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 dns-soa-record-lookup-39de4b1a
```

Example prompt: Can you look up the DNS SOA record for example.com and tell me the primary nameserver, admin contact email, serial number, and all the zone timers?

## When to prefer this

Use this endpoint when you need structured, parsed SOA data rather than raw DNS output — especially for zone health checks, serial-based change detection, or extracting admin contact and nameserver info without running command-line DNS tools. Ideal for agents automating DNS audits or monitoring pipelines where JSON output is required.

## Known failure modes

- Domain has no SOA record (non-existent zone) — returns error or empty result
- Domain does not exist (NXDOMAIN) — lookup fails
- DNS resolution timeout or upstream nameserver unreachable — returns error
- Invalid domain name format provided — returns validation error
- Rate limiting or payment failure — returns 402 or 429 error

## How this service works

DNS SOA record lookup: zone start-of-authority with primary nameserver, admin contact email, serial number and refresh/retry/expire/minimum timers, parsed into JSON. Zone health and change detection (serial). $0.01 per lookup.

## Output

A JSON object containing the domain's SOA record fields: primary nameserver (MNAME), responsible admin email (RNAME), serial number, refresh interval, retry interval, expire interval, and minimum TTL — all parsed and ready to use programmatically.
