# dns-txt-remote-subdomain

> dns-txt-remote-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 2026-10-22).

Looks up the TXT DNS record for the 'remote' subdomain of a given domain via Cloudflare DoH and reports existence, records, and TTL.

## Facts

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-txt-remote-subdomain-a365df09
```

Example prompt: Can you check if remote.example.com has any TXT DNS records set — I want to know if that subdomain exists and what records it has?

## When to prefer this

Use this endpoint when you need a fast, targeted check specifically for TXT DNS records on the 'remote' subdomain of a given domain without enumerating all subdomains. Ideal for quick existence checks, DNS audits, or pre-deployment verification where you know the hostname pattern is 'remote' and the record type is TXT.

## Known failure modes

- Domain does not exist — NXDOMAIN response with no records
- No TXT record set for the remote subdomain — empty answer section
- Invalid domain format provided — query fails or returns error
- Cloudflare DoH upstream timeout or unreachable — service error
- Payment not processed — 402 response before lookup is executed

## How this service works

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

## Output

Returns whether the remote.<domain> subdomain exists in DNS, along with any TXT record values and their TTL as resolved via Cloudflare DNS over HTTPS.
