# Bulk DNS Lookup

> Bulk DNS Lookup 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 DNS lookups for up to 20 domains in a single call, returning A records, MX records, nameservers, SPF existence, and DMARC existence per domain.

## Facts

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 bulk-dns-lookup-d831c84c
```

Example prompt: Can you do a bulk DNS lookup on these 15 domains from my lead list — example.com, acme.io, testcorp.net — and tell me which ones have A records, MX records, nameservers, and whether SPF and DMARC are set up?

## When to prefer this

Choose this endpoint when you need DNS data for multiple domains at once and want to minimize API costs — it processes up to 20 domains per $0.01 call, making it roughly 20x cheaper than individual per-domain lookups. Ideal for lead list enrichment, domain portfolio audits, and monitoring workflows where checking DNS in bulk is more efficient than sequential single-domain calls.

## Known failure modes

- Domains that do not exist or are unresolvable may return empty record sets rather than explicit errors
- Batch exceeding 20 domains may be rejected or truncated
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting if too many calls are made in rapid succession
- Malformed domain names in the input list may cause partial failures

## How this service works

Bulk DNS lookup: up to 20 domains in one $0.01 call. For each: A records, MX records, nameservers, and whether SPF and DMARC exist. Batch domain checks for lead lists, portfolio audits and monitoring at a twentieth of the per-domain price.

## Output

For each domain in the batch, the agent receives A records (IPv4 addresses), MX records with priorities, nameserver entries, and boolean flags indicating whether SPF and DMARC TXT records exist — all returned in a single response for up to 20 domains.
