## 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 batch-email-address-validator-35be442e -d '<json body>'
```

Example prompt: Can you validate this list of 250 email addresses and tell me which ones are valid and which ones have issues, with the reason codes for each?

## When to prefer this

Choose this endpoint when you need to validate between 1 and 1000 email addresses in a single API call with per-address detail codes. It is ideal for bulk list cleaning, pre-send campaign validation, or CRM hygiene where you need not just a pass/fail but also the reason code for each result. Prefer this over single-address validators when processing batches to minimize latency and cost per email.

## Known failure modes

- Batch size exceeds 1000 addresses — request rejected
- Malformed request body or non-array input — HTTP 400
- Network or DNS lookup failures causing partial results
- Rate limiting or payment failure — HTTP 402 or 429
- Some addresses return inconclusive results due to greylisting or catch-all servers

## How this service works

Batch 1-1000. Returns per-address valid plus detail codes.

## Output

An array of per-address results, each containing a valid boolean flag and one or more detail/classification codes indicating the reason for pass or failure (e.g. syntax error, domain not found, disposable address, mailbox does not exist).
