# dns-txt-git-subdomain

> dns-txt-git-subdomain is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Looks up the TXT DNS record for the git.<domain> subdomain via Cloudflare DNS-over-HTTPS and returns whether it exists, its record values, and TTL.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-git-subdomain-6263e548
```

Example prompt: Check whether git.github.com has any TXT DNS records set — use Cloudflare DoH — and tell me the record values and TTL if it exists.

## When to prefer this

Use this endpoint when you need a quick, targeted existence check for the TXT record on the git.<domain> subdomain specifically, without enumerating other subdomains. Prefer this over general DNS tools when you want a lightweight, pay-per-use lookup via Cloudflare DoH with no setup required.

## Known failure modes

- Domain does not exist — returns NXDOMAIN with no records
- git subdomain has no TXT record — returns empty record set
- Malformed domain input — may return error or unexpected response
- Cloudflare DoH upstream timeout — service may return error
- Invalid or missing query parameter — request rejected

## How this service works

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

## Output

Returns whether the TXT record for git.<domain> exists, the record values (strings), the TTL in seconds, and the DNS response code (e.g. NOERROR or NXDOMAIN).
