# dns-a-records-bulk

> dns-a-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).

Performs concurrent DNS A record lookups for up to 20 domains in a single call, returning results in input order with per-item error fields 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-a-records-bulk-503fbe30
```

Example prompt: Can you do a bulk DNS A record lookup for these 15 domains and tell me which IPs they resolve to, flagging any that fail: example.com, test.org, site.net, and the rest of this list?

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and need their DNS A records resolved efficiently in a single API call. It is preferable over making repeated single-domain /dns/a calls because it processes all domains concurrently and returns results in input order. Ideal for batch enrichment pipelines, security investigations, infrastructure audits, or any workflow where you hold a pre-built domain list and want to minimize round trips and cost.

## Known failure modes

- Domain does not exist (NXDOMAIN) — per-item error field populated
- DNS timeout for one or more domains — individual items marked as failed
- Invalid domain name format — item-level error returned
- Batch exceeds 20-domain limit — request rejected
- Network error reaching upstream DNS resolver — failure count incremented

## How this service works

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

## Output

An ordered array of DNS A record results corresponding to each input domain, where each item includes the domain's resolved IP address(es) and a per-item error field if resolution failed, plus an overall count of failures across the batch.
