# is-dns-hosted-by-vultr-bulk

> is-dns-hosted-by-vultr-bulk is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-20).

Checks whether up to 20 domains have their DNS hosted by Vultr in a single concurrent batch call, returning per-item results with error fields and a failure count.

## 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 is-dns-hosted-by-vultr-bulk-5b0d4e01
```

Example prompt: Check all 15 domains in my list and tell me which ones have their DNS hosted by Vultr — I need the results per domain with any errors flagged.

## When to prefer this

Use this endpoint when you have multiple domains (up to 20) to check for Vultr DNS hosting and want to minimize round-trips and cost compared to calling the single-domain endpoint repeatedly. Prefer this over the single endpoint whenever you have a list context, need concurrently processed results, or are building a pipeline that enriches domain records in bulk.

## Known failure modes

- Individual domain lookup failure returns per-item error field rather than crashing the batch
- Domains with no NS records may return false or an error
- More than 20 domains in a single call exceeds the batch limit
- Network timeouts from Cloudflare DoH may cause per-item errors
- Payment failure (x402) blocks the entire batch from executing

## How this service works

Bulk is dns hosted by vultr: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.

## Output

An ordered array of results matching the input domain list, where each item contains a boolean indicating whether the domain's DNS is hosted by Vultr (based on NS record matching), a per-item error field if the lookup failed, and a summary failure count for the batch.
