## 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-shopify1-lookup-55b2aabc
```

Example prompt: Check whether the shopify1 DKIM selector is correctly configured for mybrand.com — I want to know if the key is valid, what type it is, how long the public key is, and whether it's revoked.

## When to prefer this

Use this endpoint when you need to specifically verify the 'shopify1' DKIM selector for a domain — particularly for Shopify-connected stores troubleshooting transactional email delivery, auditing email authentication configuration, or confirming that Shopify's email signing key is properly published and not revoked. Prefer this over generic DNS TXT lookups when you need structured, pre-parsed DKIM field extraction rather than raw TXT record data.

## Known failure modes

- Domain does not have a shopify1._domainkey TXT record — returns not found
- DNS resolution failure via Cloudflare DoH — transient network error
- Domain is invalid or malformed — input validation error
- DKIM record exists but is malformed and cannot be parsed — parse error
- Empty p= field indicates revoked key — returned as a valid result flagging revocation

## How this service works

DKIM public key for selector "shopify1" of a domain: looks up shopify1._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 shopify1 selector will verify. $0.01 per lookup.

## Output

Returns parsed details from the shopify1._domainkey.<domain> TXT record including: DKIM version (v=), key type (k=), public key length in bits, whether the testing flag is set, and whether the key is revoked (indicated by an empty p= field). Confirms if mail signed with the shopify1 selector will successfully verify.
