# mail-provider-detect-bulk

> mail-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).

Detects the mail provider (e.g. Google Workspace, Microsoft 365, Zoho) for up to 20 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 mail-provider-detect-bulk-4813f035
```

Example prompt: Can you check which mail provider each of these domains uses — acme.com, globex.io, initech.net, umbrellacorp.com, and vandelay.biz — all in one go?

## When to prefer this

Choose this endpoint when you have a list of 2–20 domains and need mail provider information for all of them — it processes concurrently and returns results in input order, making it far more efficient than calling the single-domain endpoint repeatedly. Prefer it for batch enrichment workflows, CRM enrichment, sales prospecting, or IT audits where multiple domains must be checked in one shot.

## Known failure modes

- Domain not found or does not exist — per-item error field populated
- DNS lookup timeout for a specific domain — item marked with error, others succeed
- Invalid domain format in input — per-item validation error
- Batch exceeds 20-domain limit — request rejected
- Payment not completed (x402) — entire call rejected before processing

## How this service works

Bulk mail provider detect: 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/mail-provider endpoint (Mail provider detection for a domain). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of per-domain results matching the input order, each containing the detected mail provider name (e.g. Google Workspace, Microsoft 365, Zoho Mail, custom), plus a per-item error field if detection failed for that domain, and an overall count of failures across the batch.
