# DKIM Squarespace Selector Lookup

> DKIM Squarespace Selector Lookup 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 'squarespace' selector of a given domain, validating key type, length, testing flag, and revocation status.

## 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-squarespace-selector-lookup-e6a68651
```

Example prompt: Can you check if the Squarespace DKIM selector is properly configured for example.com — I want to know if the key is valid, what type it is, its length, and whether it's revoked or in testing mode?

## When to prefer this

Use this endpoint when you specifically need to validate the Squarespace DKIM selector for a domain — it is purpose-built for that exact selector and parses all relevant DKIM fields automatically, saving you from raw DNS lookups and manual parsing. Prefer it over generic DNS TXT lookup endpoints when you want structured DKIM field extraction (key type, length, revocation, testing flag) for Squarespace-hosted or Squarespace-mailing domains.

## Known failure modes

- Domain has no squarespace._domainkey TXT record (NXDOMAIN or empty result)
- Key is revoked — p= field is empty, verification will fail
- DNS resolution failure via Cloudflare DoH
- Malformed TXT record that cannot be parsed
- Domain input missing or invalid format

## How this service works

DKIM public key for selector "squarespace" of a domain: looks up squarespace._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 squarespace selector will verify. $0.01 per lookup.

## Output

Returns parsed DKIM TXT record details for squarespace._domainkey.<domain>, including the DKIM version tag (v=), key type (k=), RSA/EC key type label, public key bit length, whether the domain is in testing mode, and whether the key is revoked (empty p= field), along with a confirmation of whether the selector will successfully verify Squarespace-signed mail.
