## 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-video-subdomain-cloudflare-doh-18806e93
```

Example prompt: Can you check if there are any TXT records set on the video subdomain for rallylive.ca — I want to know if video.rallylive.ca exists in DNS and what records it has?

## When to prefer this

Use this endpoint when you specifically need TXT records for the video subdomain of a domain — for example, to check video hosting configuration, detect domain verification tokens, or confirm SPF records on the video host. Prefer this over full DNS enumeration tools when you only need a quick existence and record check for this one well-known subdomain pattern via Cloudflare's resolver.

## Known failure modes

- Domain does not exist — returns NXDOMAIN or equivalent
- video subdomain has no TXT records — returns empty record set
- Network or DoH resolver timeout — query fails to complete
- Malformed domain input — resolver returns error
- Cloudflare DoH service unavailable — endpoint returns error

## How this service works

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

## Output

Returns whether the video.<domain> subdomain exists in DNS, its TXT record values (e.g. SPF strings, verification tokens, or other TXT data), the TTL of those records, and the DNS response code (e.g. NOERROR or NXDOMAIN) as answered by Cloudflare DoH.
