## 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-ci-subdomain-8e362976
```

Example prompt: Can you check if the domain github.com has a ci subdomain configured — specifically the TXT DNS record for ci.github.com, and tell me if it exists and what its TTL is?

## When to prefer this

Use this endpoint when you need a fast, targeted existence check for the ci subdomain specifically and want TXT record data without enumerating all subdomains. Prefer this over general DNS lookup tools when you only care about the ci host and TXT record type, and when you want Cloudflare DoH resolution without running your own DNS client.

## Known failure modes

- Domain does not have a ci subdomain — returns non-existent/NXDOMAIN response
- Invalid or malformed domain name input — may return an error or empty result
- Cloudflare DoH upstream timeout or unavailability — request may fail
- Domain exists but has no TXT record for ci subdomain — returns empty record set
- Rate limiting or payment failure — request rejected with 402

## How this service works

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

## Output

Returns whether the ci.<domain> TXT record exists, the actual TXT record content if present, and the TTL of the record, sourced from Cloudflare DNS-over-HTTPS.
