## When to prefer this

Use this endpoint when you need a lightweight, pay-per-use DNS lookup specifically for DKIM selector records without building your own DNS resolver infrastructure. Prefer it for security reviews, email deliverability audits, or incident response where you need raw DNS data for a specific domain/selector pair quickly and cheaply.

## Known failure modes

- DKIM selector does not exist in DNS — returns empty or NXDOMAIN response
- Domain does not exist in DNS — DNS resolution failure
- Selector string malformed or domain string invalid — input validation error
- DNS timeout or temporary resolution failure — transient network error
- DKIM record exists but is malformed — raw unparsed data returned
