## 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 zendesk-dkim-dns-txt-record-lookup-9e562f34 -d '<json body>'
```

Example prompt: Can you look up the Zendesk DKIM TXT record for example.com — specifically the value at zendesk._domainkey.example.com?

## When to prefer this

Use this endpoint when you need to programmatically retrieve the Zendesk-specific DKIM TXT record (at the zendesk._domainkey selector) for a given hostname, particularly for email deliverability audits, DNS configuration checks, or verifying Zendesk mail authentication setup. Prefer the free sandbox endpoint (/v1/sandbox/dns-txt-dkim-zendesk) for testing. Use this paid endpoint when you need reliable, production-grade DNS resolution against the live DNS system.

## Known failure modes

- Hostname not found — no DNS record exists at the Zendesk DKIM selector for the given domain
- Invalid hostname format — hostname exceeds 253 characters or is empty
- DNS resolution timeout — the upstream DNS query fails to respond
- Record not published — Zendesk DKIM has not been configured for the domain, returning empty or null result

## How this service works

Call when an agent needs TXT at zendesk._domainkey.{hostname}. A different selector is a different DNS name. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/dns-txt-dkim-zendesk first.

## Output

Returns the raw TXT record value found at zendesk._domainkey.{hostname}, which typically contains the DKIM public key and policy fields used for Zendesk email signing validation.
