## 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 multi-type-dns-record-resolver-doh-d09e12a1
```

Example prompt: Can you pull all the DNS records for sendgrid.net — I need A, AAAA, MX, TXT, and NS records in one shot to audit their email deliverability setup?

## When to prefer this

Choose this endpoint when you need multiple DNS record types for a single domain in one API call rather than making separate lookups. Ideal for email deliverability audits (MX + TXT/SPF), security investigations, domain health checks, and brand protection workflows where you need A, AAAA, MX, TXT, NS, and/or CNAME records together. Prefer over the simpler A/AAAA-only sibling endpoint when you need record types beyond basic IP resolution.

## Known failure modes

- Hostname not found or NXDOMAIN — records object will be empty or indicate no such domain
- Invalid hostname format returns a 400-level error
- Requesting an unsupported record type returns an error or empty result for that type
- DoH upstream provider timeout or rate limit causes delayed or failed response
- Non-public or internal hostnames (e.g. localhost, .local) may return empty results

## How this service works

Resolve multiple DNS record types (A, AAAA, MX, TXT, NS, CNAME) in one call via DoH for deliverability and security agents

## Output

Returns a JSON object with 'ok' boolean, the queried hostname, the DNS source used, and a 'records' object keyed by record type (A, AAAA, MX, TXT, NS, CNAME) each containing the relevant DNS answers, plus a service identifier string.
