# DKIM Selector Bulk Scanner

> DKIM Selector Bulk Scanner 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).

Scans up to 20 domains concurrently for DKIM selectors in a single API call, returning per-domain results in input order with per-item error fields and a failure count.

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-scanner-7ca6fbc5
```

Example prompt: Can you scan all of these domains for their DKIM selectors at once: example.com, acme.org, testco.io, and the other 12 on my list — I want to see which ones have DKIM configured and which ones don't?

## When to prefer this

Use this endpoint when you have 2–20 domains to scan and want to avoid making multiple sequential calls to the single-domain endpoint. It processes all domains concurrently and returns results in input order with isolated per-item errors, so one bad domain does not abort the batch. Prefer the single-domain endpoint for one-off lookups or when you need to handle each domain's result independently in real time.

## Known failure modes

- Input list exceeds 20 domains — request rejected
- Individual domain DNS lookup failures reported in per-item error field
- Malformed domain names cause per-item errors without failing the whole batch
- Network timeouts for slow DNS resolvers may cause per-item failures
- Payment not attached or insufficient — 402 response before any scanning begins

## How this service works

Bulk dkim selector scan: 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/dkim-selectors endpoint (DKIM selector scan). 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 discovered DKIM selectors (same structure as the single-domain endpoint), a per-item error field if the scan failed for that domain, plus a top-level count of how many domains failed.
