## 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-static-subdomain-beb31694
```

Example prompt: Can you check if static.acmecorp.com has any TXT records in DNS — I want to know what records exist and their TTL?

## When to prefer this

Use this endpoint when you need a quick, targeted check for TXT records on the static subdomain of a given domain without enumerating all subdomains. It is ideal for verifying CDN configurations, ownership tokens, or security headers scoped to the static host, using Cloudflare DoH for reliable and fast resolution.

## Known failure modes

- Domain does not exist — returns NXDOMAIN with no records
- static subdomain has no TXT records — returns NOERROR but empty record set
- Invalid or malformed domain input — may return an error or unexpected response
- Cloudflare DoH temporarily unavailable — service call may fail or time out
- Rate limiting or payment failure for the $0.01 per lookup fee

## How this service works

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

## Output

Returns whether the static.<domain> subdomain exists in DNS, its TXT record values (if any), and the TTL of those records, as answered by Cloudflare DNS over HTTPS. Includes the DNS response code (e.g. NOERROR, NXDOMAIN).
