# dns-ns-via-cloudflare-watch

> dns-ns-via-cloudflare-watch is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-01).

Monitors DNS NS records via Cloudflare DoH for a domain and returns whether they changed since the last check, with before/after field diffs.

## 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-ns-via-cloudflare-watch-0f06b349
```

Example prompt: Watch the NS records for example.com via Cloudflare and tell me if they've changed since the last time you checked — show me what changed and when it was last seen.

## When to prefer this

Choose this endpoint when you need to detect changes in a domain's nameserver (NS) records specifically via Cloudflare's DNS resolver, with automated diffing against a stored baseline. Prefer it over plain NS lookup endpoints when your goal is change detection rather than a one-time lookup, and when you want to schedule periodic checks and receive structured before/after diffs without maintaining your own state.

## Known failure modes

- Domain not yet checked before — no previous snapshot exists, so 'changed' will be false/null on first call
- Domain does not exist or has no NS records — returns NXDOMAIN or empty record set
- Previous snapshot expired (older than 90 days) — comparison resets, treated as first call
- Network error reaching Cloudflare DoH — upstream resolver unavailable
- Invalid domain name format — request rejected with error
- Payment not provided or insufficient — x402 payment required error

## How this service works

Change watch for dns ns via cloudflare: runs the check, compares it with the result from your previous call for the same domain (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the current NS records as answered by Cloudflare DoH, a boolean 'changed' flag indicating whether the records differ from the previous check (retained for 90 days), a list of fields that changed with their before and after values, and the timestamp of when the records were last seen.
