# dns-a-status-subdomain

> dns-a-status-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 A record for the 'status' subdomain of a given domain via Cloudflare DoH and reports existence, IP records, and TTL

## Facts

- Endpoint: GET https://dns.intel.rallylive.ca/dns/host/status/a?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-20
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/dns-a-status-subdomain-02c1c6ff
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_p-1kronA1vViJCQhT0X9Z

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-status-subdomain-02c1c6ff
```

Example prompt: Does github.com have a status subdomain set up? Check the A record for status.github.com and tell me if it exists and what IP it resolves to.

## When to prefer this

Use this endpoint when you need a quick, targeted check on whether a domain has a 'status' subdomain configured (A record only), without enumerating all subdomains. Prefer it over general DNS tools when you specifically want to check the canonical status host for a domain cheaply at $0.01 per call. It is not suitable for checking other subdomain names or other record types.

## Known failure modes

- Domain has no status subdomain — returns non-existence response
- Invalid or malformed domain input — may return error or empty result
- Cloudflare DoH temporarily unavailable — upstream resolution failure
- NXDOMAIN for the subdomain — record does not exist
- Payment not fulfilled — x402 payment required error before response is returned

## How this service works

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

## Output

Returns whether status.<domain> exists as a DNS A record, the resolved IP address(es), and the TTL of those records as answered by Cloudflare DoH.
