## 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 mandrill-dkim-dns-txt-record-lookup-e19579f9 -d '<json body>'
```

Example prompt: Can you fetch the Mandrill DKIM DNS TXT record for the domain example.com — I need what's published at mandrill._domainkey.example.com?

## When to prefer this

Use this endpoint when you specifically need the Mandrill DKIM TXT record (mandrill._domainkey selector) for a given hostname. If an unpaid sandbox alternative is available at POST /v1/sandbox/dns-txt-dkim-mandrill, prefer that first to avoid the $0.007 USDC charge. Choose this over generic DNS lookup tools when you want a purpose-scoped, agent-friendly call specifically targeting Mandrill's DKIM selector.

## Known failure modes

- Record does not exist — Mandrill DKIM not configured for the given hostname
- Invalid or malformed hostname input
- DNS resolution timeout or upstream failure
- Hostname exceeds 253 character limit or is empty
- Private/reserved domain that cannot be resolved externally

## How this service works

Call when an agent needs TXT at mandrill._domainkey.{hostname}. A different selector is a different DNS name. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/dns-txt-dkim-mandrill first.

## Output

Returns the raw DNS TXT record content published at mandrill._domainkey.{hostname}, typically containing the Mandrill DKIM public key and policy fields used to authenticate outbound email.
