# Bulk Email Deliverability Report

> Bulk Email Deliverability Report 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 email authentication and deliverability configuration (SPF, DKIM, DMARC, MX, etc.) for up to 20 domains in a single concurrent call, returning per-domain results in input order with per-item error fields.

## Facts

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 bulk-email-deliverability-report-81996af8
```

Example prompt: Check the email deliverability setup — SPF, DKIM, DMARC, and MX records — for all these domains at once: acme.com, betacorp.io, gammaltd.co.uk, deltainc.net, and epsilongroup.org.

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and want to check their email deliverability configuration in a single concurrent call rather than making multiple individual requests. It is more efficient and cost-effective than calling the single-domain endpoint repeatedly. Prefer this over the single endpoint whenever you are processing a batch of domains for auditing, onboarding, or portfolio analysis workflows.

## Known failure modes

- Input list exceeds 20 domains — request rejected or truncated
- Individual domain lookup failure captured in per-item error field without failing the whole batch
- Invalid domain format in input list causes per-item error
- DNS timeout for specific domains results in per-item error with failure counted
- Payment not accepted or x402 auth missing — entire request rejected
- Empty input list returns empty results array

## How this service works

Bulk email deliverability report: 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 /email/deliverability-report endpoint (Email authentication and deliverability report for a domain in one call). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

Returns an ordered array of per-domain deliverability reports matching the input order. Each item contains the same data as the single-domain endpoint: SPF, DKIM, and DMARC record analysis, MX record details, overall deliverability assessment, and a per-item error field if that domain lookup failed. A top-level failure count is also included.
