# dns-aaaa-media-subdomain

> dns-aaaa-media-subdomain is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Looks up the AAAA (IPv6) DNS record for the 'media' subdomain of a given domain via Cloudflare DoH and reports its existence, records, and TTL.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-media-subdomain-f921194b
```

Example prompt: Can you check whether media.rallylive.ca has an AAAA record — I want to know if that media subdomain is live and what its IPv6 address and TTL are?

## When to prefer this

Use this endpoint when you need a quick, targeted IPv6 DNS existence check specifically for the 'media' subdomain of a domain, without performing broad subdomain enumeration. Prefer it over general DNS tools when you want Cloudflare DoH-sourced results with TTL data and a clear existence flag, and when cost efficiency ($0.01/lookup) matters for high-volume checks.

## Known failure modes

- Domain does not exist — NXDOMAIN response returned
- media subdomain has no AAAA record — returns empty or negative result
- Invalid or malformed domain name input — query fails
- Cloudflare DoH service unavailable — timeout or upstream error
- Rate limiting or payment issues — 402 payment required if x402 not satisfied

## How this service works

AAAA record of media.<domain>: looks up the media 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 media without enumerating subdomains. $0.01 per lookup.

## Output

Returns whether the AAAA record for media.<domain> exists, the resolved IPv6 address(es), and the TTL of the record, sourced via Cloudflare DNS over HTTPS.
