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-store-subdomain-d53ad57d
```

Example prompt: Can you check if store.acmecorp.com has any TXT DNS records set up — I want to know if the store subdomain exists and what records it has?

## When to prefer this

Use this endpoint when you need a fast, targeted existence and TXT record check specifically for the 'store' subdomain of a given domain, without enumerating all subdomains. It uses Cloudflare DoH for reliable, low-latency resolution. Prefer it over full DNS enumeration tools when you only need to verify whether a store host is configured or carries a specific TXT value (e.g. domain ownership tokens, SPF, or service verification strings).

## Known failure modes

- Domain does not exist — NXDOMAIN response with no records
- No TXT record set on the store subdomain — empty records array returned
- Invalid or malformed domain input — request may fail or return error
- Cloudflare DoH resolver temporarily unavailable — upstream timeout or error
- Rate limiting or payment failure — endpoint returns 402 or similar error

## How this service works

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

## Output

Returns whether the store.<domain> TXT record exists, the full list of TXT record values, the TTL in seconds, and the DNS response code from Cloudflare's DoH resolver
