## 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-mailchimp-bulk-checker-317fa5ab
```

Example prompt: Check whether Mailchimp is authorized by the SPF records for all of these domains: acme.com, betastore.io, gammatech.net, deltasoft.org, and epsilon.co — give me the result for each one and flag any that failed.

## When to prefer this

Use this endpoint when you have a list of 2–20 domains to check for Mailchimp SPF authorization and want to minimize API round-trips. Prefer this over the single-domain endpoint when processing customer onboarding batches, running deliverability audits, or sweeping a portfolio. It processes domains concurrently so latency scales much better than serial single calls at $0.10 for the whole batch.

## Known failure modes

- Invalid or unreachable domain returns a per-item error with failure count incremented
- DNS lookup timeout causes per-item failure without blocking other results
- Malformed input list (exceeding 20 domains) may result in a batch rejection
- Domain with no SPF record returns a negative authorization result
- Network issues during concurrent DNS resolution may increase partial failure count

## How this service works

Bulk spf authorizes mailchimp: 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

Returns an ordered array of per-domain results matching the input order, each containing whether the domain's SPF record authorizes Mailchimp, a per-item error field if the check failed, and an overall failure count for the batch.
