# email-provider-detect-bulk

> email-provider-detect-bulk 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).

Identifies the email hosting provider (e.g. Google Workspace, Microsoft 365, custom) for up to 20 email addresses or domains in a single concurrent batch call, returning results in input order with per-item error fields.

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 email-provider-detect-bulk-10be3ab1
```

Example prompt: Can you detect the email provider for each of these addresses — alice@acmecorp.com, bob@techfirm.io, carol@startup.co — and tell me which hosting service each one uses?

## When to prefer this

Prefer this endpoint when you need to enrich a list of email addresses or domains with their hosting provider in bulk (up to 20 at once) and want concurrent processing with results in input order. It is more cost-efficient than calling the single /email/provider endpoint 20 times separately. Best suited for CRM enrichment workflows, sales prospecting pipelines, or deliverability pre-checks where you already hold a list of contacts.

## Known failure modes

- Invalid or malformed email address in the batch — per-item error field populated, item skipped
- Batch size exceeds 20 items — request rejected
- Unresolvable domain (no MX records or DNS failure) — per-item error returned
- Network timeout to upstream DNS/MX lookup — item marked as failed
- All 20 items fail — full failure count returned with no provider data

## How this service works

Bulk email provider detect: up to 20 emails 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/provider endpoint (Email provider detection for an address or domain). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of results matching the input list, where each item contains the detected email provider name and classification for that address or domain. Each item also includes a per-item error field indicating any lookup failure. A top-level failure count summarizes how many items could not be resolved.
