# DNS SRV Records Bulk Lookup

> DNS SRV Records Bulk 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).

Looks up DNS SRV records for up to 20 domains concurrently in a single call, returning results in input order with per-item error reporting.

## 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-srv-records-bulk-lookup-373402d3
```

Example prompt: I have a list of 15 domains and I need to pull the DNS SRV records for all of them at once — can you do a bulk SRV lookup and show me the results with any failures flagged per domain?

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and need SRV records for all of them, avoiding the overhead and latency of sequential single-domain calls. Prefer it over repeated single /dns/srv calls when concurrency matters and you want consolidated error handling in a single response.

## Known failure modes

- Domain not found or does not exist — per-item error returned with DNS NXDOMAIN
- No SRV records exist for a domain — empty record set returned for that item
- Input list exceeds 20 domains — request rejected or truncated
- Malformed domain name in list — per-item error for affected entries
- DNS resolver timeout — per-item timeout error for affected domains
- Network connectivity issues to upstream DNS — may affect all items in batch

## How this service works

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

## Output

An ordered array of SRV lookup results matching the input domain list. Each item contains the SRV records for that domain (service, protocol, priority, weight, port, target) or a per-item error field if the lookup failed. A top-level failure count summarizes how many domains errored.
