# DNS TXT Records Bulk Lookup

> DNS TXT 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 TXT records for up to 20 domains concurrently 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-txt-records-bulk-lookup-56a1599e
```

Example prompt: Can you fetch the DNS TXT records for these 10 domains all at once: example.com, acme.org, foo.io, bar.net, baz.co, qux.dev, alpha.com, beta.io, gamma.net, delta.org?

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and need TXT records for all of them efficiently without making sequential single-domain calls. It is preferable over the single /dns/txt endpoint whenever you are doing batch enrichment, auditing email security configurations (SPF/DKIM/DMARC), verifying domain ownership tokens at scale, or feeding domain intelligence pipelines. Choose this over rolling your own concurrent DNS lookups when you want consistent ordered results with built-in per-item error handling.

## Known failure modes

- Domain does not exist or has no TXT records — per-item error field populated
- Input list exceeds 20 domains — request may be rejected or truncated
- Malformed domain name in input — per-item error returned for that entry
- DNS resolution timeout for a specific domain — per-item error with timeout indication
- Network or upstream DNS resolver failure — whole batch may fail with 5xx error
- Payment not included or insufficient — x402 payment required error

## How this service works

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

## Output

An ordered array of results matching the input domain list, where each item contains the DNS TXT records for that domain (same structure as the single /dns/txt endpoint), a per-item error field if the lookup failed, and an overall count of failures across the batch.
