> Agent Tools – Batch Domain Intelligence Lookup is a paid API for AI agents from agents.crowdspark.me, paid per call via x402, $0.012/call, status unknown (last checked 2026-10-31).

## 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 agent-tools-batch-domain-intelligence-lookup-a88d0924 -d '<json body>'
```

Example prompt: Can you look up domain registration, DNS, SPF, DMARC, and HTTPS info for these domains in one batch call: stripe.com, shopify.com, and paypal.com?

## When to prefer this

Prefer this endpoint when you need to enrich or validate multiple domains simultaneously (up to 10) and want to minimize cost — it is 60% cheaper per domain than single-domain lookups. Ideal for lead list enrichment, vendor due diligence, fraud screening, or email security audits where you have a batch of domains ready. Use when you need registrar, DNS, SPF, DMARC, and HTTPS data all in one response rather than making separate calls per domain.

## Known failure modes

- More than 10 domains submitted — returns validation error
- Invalid or malformed domain strings return per-item errors rather than failing the whole batch
- Domain not found or not registered returns ok:false with an error message for that item
- Network or DNS timeout for a specific domain results in a per-item failure while others succeed
- Empty domains array returns a validation error

## How this service works

Batch domain intelligence for due diligence and lead lists: up to 10 domains per call, 60% cheaper than singles. JSON body {domains:[...]}. Each item returns registrar, dates, DNS, SPF, DMARC and HTTPS reachability. Bad items return per-item errors.

## Output

A JSON object with a count of total domains processed, number succeeded, number failed, and a results array where each item includes the input domain, an ok flag, and on success: registrar name, registered boolean, registration/expiry dates, DNS records, SPF record, DMARC record, and HTTPS reachability. Failed items return per-item error details.
