## 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-sandbox-subdomain-0699b468
```

Example prompt: Can you check whether sandbox.rallylive.ca has a TXT DNS record — I want to know if the sandbox subdomain exists and what its records and TTL look like.

## When to prefer this

Use this endpoint when you need a fast, single-purpose check for whether a domain has a sandbox subdomain with TXT records configured, without needing to enumerate all subdomains. Ideal for infrastructure audits, pre-deployment checks, or domain intelligence workflows where the sandbox host specifically is the target.

## Known failure modes

- Domain does not exist — no records returned
- sandbox subdomain has no TXT record — existence reported as false
- Invalid or malformed domain input
- DoH upstream timeout or resolution failure
- Rate limiting or payment failure (x402)

## How this service works

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

## Output

Returns whether the sandbox.<domain> TXT record exists, the actual TXT record values if present, and the TTL of the record, all resolved via Cloudflare DNS over HTTPS.
