> nameserver-health-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 nameserver health for up to 20 domains in a single concurrent call, returning per-item results in input order with 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 nameserver-health-bulk-17365b35
```

Example prompt: Can you check the nameserver health for all 15 domains in my portfolio — I need to know if any nameservers are down or unhealthy, and get a summary of failures.

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and need nameserver health checked efficiently in a single call. It processes concurrently and returns results in input order with structured per-item errors, making it ideal for portfolio monitoring, pre-deployment validation, or triage workflows. Prefer over the single-domain endpoint when you have multiple domains to check and want to minimize latency and API calls.

## Known failure modes

- More than 20 domains submitted — batch size limit exceeded
- Invalid or malformed domain name in the list — per-item error field populated
- Nameserver lookup timeout — item marked as failed with error detail
- Network error reaching upstream DNS — per-item error returned
- Missing required input parameter — request rejected

## How this service works

Bulk nameserver health: 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/nameserver-health endpoint (Nameserver health for a domain). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An array of per-domain nameserver health results returned in the same order as the input list. Each item matches the single-domain /dns/nameserver-health response and includes a per-item error field. A top-level failure count summarizes how many domains had unhealthy or unreachable nameservers.
