# dns-txt-via-cloudflare-watch

> dns-txt-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 2026-10-21).

Monitors DNS TXT records for a domain via Cloudflare DoH, returning the current records plus a change diff (changed flag, before/after field values) compared to the previous check stored for up to 90 days.

## 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-via-cloudflare-watch-82a8a60f
```

Example prompt: Keep an eye on the DNS TXT records for example.com using Cloudflare and let me know if anything has changed since the last check — show me what changed, what it was before, and what it is now.

## When to prefer this

Choose this endpoint when you need to detect changes in DNS TXT records (SPF, DKIM, domain verification tokens, DMARC) over time using Cloudflare as the resolver. It is ideal for scheduling periodic checks and receiving structured diffs rather than just the current record state. Prefer it over a plain TXT lookup endpoint when your goal is change detection and alerting, and over other resolver-based watch endpoints when Cloudflare's answer specifically is what matters (e.g. for CDN or Cloudflare-proxied domain behavior).

## Known failure modes

- Domain does not exist or returns NXDOMAIN — returns current NXDOMAIN response with no diff if no prior result exists
- No previous check stored (first call) — changed will be false or undefined, no diff available
- Cloudflare DoH upstream timeout or error — may return an error response code instead of records
- Invalid or malformed domain input — may return an error or empty result
- Rate limiting or payment failure — call rejected before check is executed

## How this service works

Change watch for dns txt 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 DNS TXT records as answered by Cloudflare DoH, a boolean indicating whether the records changed since the previous call for the same domain, a diff object showing which fields changed with their before and after values, and a timestamp of when the records were last seen. Previous results are retained server-side for up to 90 days for comparison.
