## 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-record-lookup-for-pop-domain-subdomain-0c5f133d
```

Example prompt: Can you check if there's a TXT record on the pop subdomain for gmail.com — I want to know if it exists and what the record says?

## When to prefer this

Choose this endpoint when you need a quick, targeted check for a TXT record specifically on the pop.<domain> subdomain without performing broad subdomain enumeration. Ideal for email infrastructure checks, domain verification workflows, or auditing a known common subdomain using Cloudflare's reliable DoH resolver.

## Known failure modes

- Domain does not have a pop subdomain — returns NXDOMAIN or empty records
- Invalid or malformed domain input causing lookup failure
- Cloudflare DoH service unavailable or timeout
- Domain uses private/split-horizon DNS not accessible via Cloudflare
- Rate limiting or payment failure at $0.01 per call

## How this service works

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

## Output

Returns whether the pop.<domain> TXT record exists, along with the full record content(s) and TTL if present, and the DNS response code (e.g. NOERROR, NXDOMAIN) as resolved through Cloudflare DNS over HTTPS
