# DKIM Selector Bulk Check

> DKIM Selector Bulk Check 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 DKIM selector DNS records for up to 20 domains concurrently in a single call, returning per-item results in input order with a failure count.

## 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 dkim-selector-bulk-check-0960b0f4
```

Example prompt: Can you check the DKIM records for all 15 domains in my list — example.com, acme.org, and the rest — and tell me which ones are misconfigured or missing, with a count of how many failed?

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and need DKIM records checked in a single round trip rather than making sequential calls to the single-domain endpoint. Ideal for batch enrichment pipelines, onboarding verification flows, and portfolio audits where latency and call count matter. For a single domain, the /email/dkim endpoint is simpler and cheaper.

## Known failure modes

- More than 20 domains submitted — exceeds batch limit
- DNS timeout for one or more domains — captured in per-item error field
- Invalid domain format in input — per-item error returned
- Payment not received — x402 payment required response
- No input domains provided — validation error

## How this service works

Bulk dkim selector check: 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/dkim endpoint (DKIM check for a domain). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered list of per-domain results mirroring the input order, each containing the same DKIM check data as the single-domain endpoint (DKIM record presence, selector details, validity), plus a per-item error field for any failures and a top-level count of how many items failed.
