## 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-staging-subdomain-1de7653c
```

Example prompt: Can you check if staging.acme.com has any TXT records in DNS and what they say?

## When to prefer this

Use this endpoint when you need a quick, targeted check of TXT records specifically on the staging.<domain> subdomain without running a full subdomain enumeration. Ideal for DevOps, deployment verification, or domain ownership checks on staging environments. Choose this over general DNS tools when you only need staging and want results routed through Cloudflare DoH for reliability.

## Known failure modes

- Domain does not exist — returns NXDOMAIN or no records found
- staging subdomain has no TXT records — returns empty record set
- Network or Cloudflare DoH resolver unavailable — may return error or timeout
- Invalid domain format provided — may return error or no result
- Payment of $0.01 USDC not fulfilled — request rejected

## How this service works

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

## Output

Returns whether staging.<domain> exists in DNS, its TXT record values (if any), the TTL, and the response code — answered via Cloudflare's 1.1.1.1 DNS over HTTPS resolver.
