## 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-mailerlite-f262b007
```

Example prompt: Check if the MailerLite DKIM selector is properly configured for example.com — tell me the key type, key length, whether it's revoked or in testing mode, and if emails signed with the mailerlite selector will actually verify.

## When to prefer this

Use this endpoint specifically when you need to verify MailerLite's DKIM email signing configuration for a domain. It is purpose-built for the mailerlite selector and parses all key DKIM attributes in a single call, saving you from raw DNS lookups and manual TXT record parsing. Prefer this over generic DNS TXT lookup endpoints when the goal is MailerLite email deliverability validation.

## Known failure modes

- Domain has no mailerlite._domainkey TXT record — returns not found or empty result
- DKIM record is malformed or unparseable — parsing error returned
- Domain does not exist or has no DNS records — DNS resolution failure
- Revoked key (empty p=) detected — returned as revoked flag, not an error
- Cloudflare DoH upstream timeout — transient lookup failure
- Invalid domain input — request validation error

## How this service works

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

## Output

Returns the parsed DKIM TXT record for mailerlite._domainkey.<domain>, including: v= version, k= key type (e.g. RSA), public key length in bits, whether the testing flag (t=y) is set, and whether the key is revoked (empty p= field). Indicates overall whether MailerLite-signed emails will pass DKIM verification for the domain.
