## 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-zendesk2-ec0a1d10
```

Example prompt: Check the DKIM configuration for the zendesk2 selector on acme.com — I need to know if the key is valid, what type and length it is, and whether it's revoked or in testing mode.

## When to prefer this

Use this endpoint when you specifically need to verify the 'zendesk2' DKIM selector for a domain — i.e., when troubleshooting Zendesk email deliverability, auditing email authentication for domains using Zendesk, or checking whether a domain's Zendesk DKIM key is active, revoked, or in testing mode. Prefer this over generic DNS lookup tools when you need the parsed, structured output (key type, length, revocation status) rather than a raw TXT record string.

## Known failure modes

- Domain has no zendesk2._domainkey TXT record — returns not-found or empty result
- Key is revoked (p= is empty) — returned as a revocation flag rather than an error
- DNS resolution failure via Cloudflare DoH — network or upstream error
- Malformed TXT record that cannot be parsed — may return raw value without structured fields
- Invalid or non-existent domain input — DNS NXDOMAIN response

## How this service works

DKIM public key for selector "zendesk2" of a domain: looks up zendesk2._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 zendesk2 selector will verify. $0.01 per lookup.

## Output

Returns parsed DKIM TXT record details for the zendesk2 selector, including: the v= (version) tag, k= (key type, e.g. RSA), the raw public key, public key bit length, whether the testing flag (t=y) is set, and whether the key is revoked (empty p= field). Confirms whether Zendesk-signed mail will pass DKIM verification.
