# dns-ns-records-bulk

> dns-ns-records-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).

Looks up DNS NS (nameserver) records for up to 20 domains in a single concurrent batch call, returning results in input order with per-item errors and a failure count.

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-ns-records-bulk-964e6e96
```

Example prompt: Look up the DNS nameserver (NS) records for all of these domains at once: example.com, acme.org, test.io, and 5 others I'll paste in — I need the authoritative nameservers for each, plus a note on any that fail.

## When to prefer this

Use this endpoint when you need NS records for multiple domains (up to 20) and want to minimize round-trips; it processes concurrently and returns results in input order, making it far more efficient than issuing 20 sequential single-domain NS lookups. Prefer it over the single /dns/ns endpoint whenever your agent holds a list of domains. Ideal for domain portfolio audits, DNS migration verification, and bulk enrichment pipelines.

## Known failure modes

- Domain does not exist or has no NS records — per-item error field populated
- Invalid domain name format — per-item error returned for that entry
- Batch exceeds 20 domains — request rejected or truncated
- DNS timeout for one or more domains — affected items flagged with error, others succeed
- Network failure reaching the DNS resolver — entire batch may fail
- Payment not provided or insufficient — 402 Payment Required response

## How this service works

Bulk dns ns records: 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/ns endpoint (DNS NS record lookup). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of results matching the input domain list, where each item contains the domain's NS records (authoritative nameservers) or a per-item error message if the lookup failed, plus a top-level count of how many domains failed to resolve.
