## 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-record-lookup-for-mysql-subdomain-40f3374c
```

Example prompt: Can you check if mysql.acme.com has an IPv6 AAAA DNS record — I want to know if the mysql subdomain exists and what its TTL is?

## When to prefer this

Use this endpoint when you need a quick, targeted existence check for the mysql subdomain under a specific domain, specifically for IPv6 (AAAA) records, without enumerating all subdomains. Prefer this over generic DNS tools when you want a low-cost ($0.01), Cloudflare DoH-backed single-host check for common infrastructure hostnames like mysql.

## Known failure modes

- Domain does not exist — NXDOMAIN returned, no records found
- mysql subdomain has no AAAA record (may have A record instead)
- Cloudflare DoH unreachable — network or upstream failure
- Invalid domain format provided — query may fail or return unexpected results
- Rate limiting or payment failure ($0.01 USDC per call)

## How this service works

AAAA record of mysql.<domain>: looks up the mysql host under the domain you give (AAAA via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like mysql without enumerating subdomains. $0.01 per lookup.

## Output

Returns whether the mysql.<domain> AAAA record exists, the resolved IPv6 address(es), and the TTL value from Cloudflare DoH. If no record is found, returns a non-existence indicator.
