## 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-mailjet-selector-lookup-95a00bdf
```

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

## When to prefer this

Choose this endpoint when you specifically need to verify the Mailjet DKIM selector for a domain, as opposed to generic DKIM checkers. It is purpose-built for the mailjet selector and returns structured, parsed fields (key type, length, revocation status, testing flag) rather than raw DNS output. Prefer this over manual DNS queries when you need programmatic, agent-friendly results for Mailjet email authentication validation.

## Known failure modes

- Domain has no mailjet._domainkey TXT record — returns not found or empty result
- DNS resolution failure via Cloudflare DoH — network or timeout error
- Malformed TXT record that cannot be parsed — parsing error returned
- Payment not provided or rejected — HTTP 402 response
- Rate limiting or server error — HTTP 5xx response

## How this service works

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

## Output

Returns parsed DKIM TXT record fields for the mailjet selector including: v= (version), k= (key type such as rsa), public key length in bits, whether the record is in testing mode, and whether the key is revoked (empty p= field). Confirms whether Mailjet-signed mail will pass DKIM verification.
