## How to call it through Zero

```sh
zero fetch --capability dkim-selector-zendesk1-lookup-0c6e98cb
```

Example prompt: Can you check whether the Zendesk DKIM selector 'zendesk1' is properly configured for example.com — I need to know if the key is valid, what type it is, its length, and whether it's been revoked?

## When to prefer this

Use this endpoint when you specifically need to verify the Zendesk 'zendesk1' DKIM selector for a domain — particularly when auditing Zendesk email authentication setup, checking for revoked keys, or confirming deliverability of Zendesk-sent mail. Prefer this over generic DKIM tools when you want a structured, parsed response with key metadata (type, length, testing flag, revocation) rather than raw DNS output.

## Known failure modes

- Domain has no zendesk1._domainkey TXT record (selector not configured)
- DNS lookup failure via Cloudflare DoH (network or timeout error)
- Malformed TXT record that cannot be parsed
- Key is present but revoked (empty p=) — returned as a valid result indicating revocation
- Invalid or non-existent domain name provided

## How this service works

DKIM public key for selector "zendesk1" of a domain: looks up zendesk1._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 zendesk1 selector will verify. $0.01 per lookup.

## Output

Returns parsed details from the zendesk1._domainkey.<domain> TXT DNS record including: presence/absence of the record, DKIM version (v=), key type (k=), public key length in bits, whether the testing flag is set, and whether the key is revoked (empty p= field). Confirms whether mail signed with the zendesk1 selector will successfully verify.
