# DNS A Record Lookup for media Subdomain

> DNS A Record Lookup for 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 2026-10-19).

Looks up the A (IPv4) DNS record for the media.<domain> subdomain via Cloudflare DoH and reports whether it exists, its IP 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-a-record-lookup-for-media-subdomain-7aa5fb62
```

Example prompt: Can you check if media.spotify.com has an A record configured — I want to know the IP it resolves to and the TTL?

## When to prefer this

Use this endpoint when you need a quick, point-in-time IPv4 address lookup for specifically the 'media' subdomain of a domain, and want to confirm existence plus TTL without doing broader subdomain enumeration. Prefer this over general DNS tools when you need a lightweight, pay-per-use check with Cloudflare DoH reliability for this exact common host pattern.

## Known failure modes

- Domain does not exist or has no media subdomain — returns no records found
- Invalid or malformed domain input — may return an error or empty result
- Cloudflare DoH service unavailable — upstream DNS resolution failure
- Rate limiting or payment failure at $0.01 per lookup — request rejected
- NXDOMAIN response when subdomain is not configured

## How this service works

A record of media.<domain>: looks up the media host under the domain you give (A 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 media.<domain> A record exists, the resolved IPv4 address(es), and the TTL value of the DNS record, queried via Cloudflare DNS over HTTPS.
