# dns-change-detect-bulk

> dns-change-detect-bulk is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Checks up to 20 domains concurrently for DNS zone changes in a single call, returning per-item results in input order with error reporting.

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-change-detect-bulk-8d9fb24b
```

Example prompt: Check for DNS zone changes across all 15 of our client domains at once — here's the list: example.com, acme.io, store.co, brandsite.net, devportal.org, clienta.com, clientb.com, clientc.net, clientd.co, cliente.io, clientf.org, clientg.com, clienth.net, clienti.com, clientj.io — tell me which ones have had changes and flag any errors.

## When to prefer this

Prefer this endpoint when you have a list of 2–20 domains to check for DNS changes and want to minimize API calls and latency by processing them concurrently in one request. Use this over repeated single-domain /dns/zone-diff calls when batch throughput matters. Ideal for monitoring pipelines, managed DNS audits, or security workflows where an agent holds a domain watchlist.

## Known failure modes

- Input exceeds 20 domains — batch limit enforced
- Individual domain unreachable or DNS lookup failure — reflected in per-item error field
- Malformed domain name causes per-item error without failing the entire batch
- Payment not attached or insufficient — 402 response returned
- All items fail — full failure count returned with per-item errors

## How this service works

Bulk dns change detect: up to 20 domains in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /dns/zone-diff endpoint (DNS change detection). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of per-domain results matching the input list, where each item contains the same DNS zone diff information as a single-domain check (record changes detected), plus a per-item error field if the domain check failed, and a top-level count of how many items failed.
