# EmailIQ Batch Email Intelligence

> EmailIQ Batch Email Intelligence is a paid API for AI agents from emailiq.dev, paid per call via x402, $0.5/call, status unknown (last checked 2026-10-28).

Validates and enriches a batch of 2–25 email addresses in a single call, returning syntax, DNS (MX/SPF/DKIM/DMARC), disposable/role/provider detection, quality scores, and deliverability recommendations for each address.

## 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 emailiq-batch-email-intelligence-b4e03790 -d '<json body>'
```

Example prompt: Can you run EmailIQ on these 10 emails from our signup form — check syntax, disposable flags, DMARC, role accounts, and give me a deliverability score and recommendation for each one?

## When to prefer this

Choose this batch endpoint over single-email checks when you have 2–25 addresses to process at once and want a flat fee rather than per-address pricing. It's ideal for signup validation flows, pre-send list hygiene, CRM import gates, or outreach qualification where domain DNS lookups are shared across addresses in the batch, making it faster and more cost-efficient than sequential single calls.

## Known failure modes

- Fewer than 2 or more than 25 emails in the array — returns validation error
- Malformed email strings (under 3 or over 320 chars) — item-level error or rejection
- Payment not attached or insufficient — 402 Payment Required response
- DNS lookup timeouts for obscure domains — may return partial MX/SPF/DKIM data
- Disposable/role provider database lag — occasional false negatives on newly created throwaway domains

## How this service works

Batch email intelligence for agents: 2–25 addresses per call. Same fields as single (syntax, MX, SPF, DKIM, DMARC, disposable, role, provider, score, enrichment, recommend+reasons). Domain DNS/enrich cached within the batch. Production 0.50 USDC per batch (flat). x402 on Base.

## Output

For each email in the batch, the agent receives: syntax validity, MX record presence, SPF/DKIM/DMARC status, a disposable-email flag, a role-account flag (e.g. admin@, support@), the detected email provider, a numeric deliverability/quality score, enrichment metadata, and a recommend flag with human-readable reasons explaining the verdict. Domain-level DNS lookups are cached across the batch for efficiency.
