## 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-id-subdomain-ba612ac0
```

Example prompt: Can you check if the id subdomain of rallylive.ca has a TXT DNS record and tell me what it says and the TTL?

## When to prefer this

Use this endpoint when you need a fast, point-in-time check of whether the 'id' host under a specific domain has TXT records configured, without broader subdomain enumeration. Prefer this over general DNS tools when you want a focused, pay-per-use lookup specifically for the 'id' subdomain via Cloudflare DoH.

## Known failure modes

- Domain does not exist — returns non-existence response
- id subdomain has no TXT records — returns empty or NXDOMAIN
- Network or DoH upstream error — resolver unavailable
- Invalid or malformed domain input — error or empty result
- Payment not received (x402) — request rejected before lookup

## How this service works

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

## Output

Returns whether the id.<domain> TXT record exists, the record content(s), and the TTL value as resolved by Cloudflare DNS over HTTPS.
