## 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 dns-aaaa-lookup-via-cloudflare-1-1-1-1-doh-6109f838
```

Example prompt: What AAAA records does Cloudflare 1.1.1.1 return for example.com — include the TTL, whether DNSSEC was validated, and how fast the resolver answered?

## When to prefer this

Choose this endpoint when you specifically need to know how Cloudflare 1.1.1.1 resolves IPv6 (AAAA) records for a domain — useful for resolver comparison, propagation checks, detecting Cloudflare-specific filtering, or verifying DNSSEC validation from Cloudflare's perspective. Prefer this over generic DNS tools when the Cloudflare resolver's view is specifically relevant, or when answer latency and DNSSEC status from 1.1.1.1 are needed.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- Domain has no AAAA records — returns NOERROR with empty answer section
- Resolver-side failure — returns SERVFAIL response code
- Invalid or malformed domain name input — may return error or SERVFAIL
- DNSSEC validation failure — resolver may return SERVFAIL if chain of trust is broken

## How this service works

AAAA records for a domain as answered by Cloudflare 1.1.1.1 (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.

## Output

Returns the AAAA records (IPv6 addresses) for the queried domain as answered by Cloudflare 1.1.1.1 via DNS over HTTPS, along with the TTL of those records, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the resolver performed DNSSEC validation, and the resolver's answer latency in milliseconds.
