## 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 bulk-burnermail-io-disposable-email-checker-2a627084
```

Example prompt: I have a list of 15 email addresses from new signups — can you check all of them at once to see if any are burnermail.io disposable addresses so I can flag the throwaway accounts?

## When to prefer this

Use this endpoint when you have a list of 2–20 email addresses and need to check each for burnermail.io disposable status in a single API call rather than making individual requests. It is the right choice for batch fraud screening, lead list audits, or signup validation pipelines where concurrency and ordered results matter. If you only need to check a single email, prefer the single-item burnermail.io endpoint instead.

## Known failure modes

- Batch exceeds 20 items — only up to 20 emails supported per call
- Malformed email addresses in the input list cause per-item errors with a non-null error field
- Network or upstream DNS failures may increment the failure count for affected items
- Empty input list returns no results
- Invalid query parameter structure returns an error response

## How this service works

Bulk is email on burnermail io: up to 20 emails 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 results matching the input email list, where each item contains whether the email is hosted on burnermail.io (true/false), any per-item error information if the check failed, plus a top-level failure count indicating how many items could not be resolved.
