# DKIM Selector Lookup – Klaviyo

> DKIM Selector Lookup – Klaviyo is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Looks up and parses the DKIM public key for the 'klaviyo' selector of a given domain, confirming Klaviyo-signed mail will verify correctly.

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 dkim-selector-lookup-klaviyo-9eae1187
```

Example prompt: Can you check whether example.com has a valid Klaviyo DKIM record set up — specifically whether the klaviyo selector key exists, what type and length it is, and whether it's been revoked?

## When to prefer this

Use this endpoint when you specifically need to verify the Klaviyo email sender DKIM configuration for a domain — it is purpose-built for the klaviyo selector and returns pre-parsed fields (key type, length, revocation status) rather than raw DNS TXT data. Prefer it over generic DNS TXT lookups when you want structured DKIM analysis without parsing the record yourself.

## Known failure modes

- Domain has no klaviyo._domainkey TXT record — returns not-found or empty result
- Key is revoked (empty p= value) — returned but flagged as invalid
- DNS resolution failure via Cloudflare DoH — network or timeout error
- Malformed TXT record that cannot be parsed — partial or error result
- Payment not made — 402 response blocking the lookup

## How this service works

DKIM public key for selector "klaviyo" of a domain: looks up klaviyo._domainkey.<domain> (TXT, Cloudflare DoH) and parses v=, k=, key type, public-key length, testing flag and whether the key is revoked (empty p=). Confirms that mail signed with the klaviyo selector will verify. $0.01 per lookup.

## Output

Returns parsed DKIM TXT record fields for the klaviyo selector: version (v=), key type (k=), public key length in bits, whether the domain is in testing mode, and whether the key is revoked (empty p= field). Also indicates overall validity — whether Klaviyo-signed mail will pass DKIM verification.
