## 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 spf-authorizes-mandrill-bulk-checker-6daf595b
```

Example prompt: Check whether Mandrill is authorized to send email for all of these domains at once: example.com, acme.org, testco.io — look up their SPF records and tell me which ones include Mandrill and which ones don't.

## When to prefer this

Use this endpoint when you need to check Mandrill SPF authorization for multiple domains simultaneously — it processes up to 20 domains concurrently in a single $0.10 call, making it far more efficient than calling the single-domain endpoint repeatedly. Prefer this when an agent holds a list of domains and needs batch enrichment of SPF/Mandrill authorization status.

## Known failure modes

- Invalid or malformed domain names in the input list result in per-item errors
- DNS lookup failures (e.g. NXDOMAIN) are captured in per-item error fields and counted in failure count
- Batch size exceeding 20 domains may be rejected or not processed beyond the limit
- Network or upstream DoH (Cloudflare) timeout results in error for affected domain items
- Payment failure (x402) prevents the batch from being processed at all

## How this service works

Bulk spf authorizes mandrill: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.

## Output

An ordered array of per-domain results (matching input order), each indicating whether Mandrill is authorized in the domain's SPF record, along with a per-item error field for any lookup failures and an overall failure count across the batch.
