## 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-email-address-validator-74bbe7db
```

Example prompt: I have a list of 15 email addresses from our sign-up form — can you validate all of them at once and tell me which ones are invalid or failing, along with a total count of bad ones?

## When to prefer this

Choose this endpoint when you need to validate multiple email addresses at once (up to 20) and want results back in a single call rather than making 20 sequential requests. It is more efficient and cost-effective than calling the single /validate-email endpoint repeatedly. Ideal for batch processing sign-up forms, mailing list hygiene, or CRM data audits where you have a known list of addresses to check concurrently.

## Known failure modes

- Batch exceeds 20 items — only up to 20 emails are accepted per call
- Malformed input list or missing required query parameters returns an error
- Individual item errors are captured per-item rather than failing the whole batch
- Network timeout if concurrent checks take too long
- Invalid input schema returns a 400-level error

## How this service works

Bulk validate email address: up to 20 emails 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 /validate-email endpoint (Validate email address). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of per-item validation results matching the input order, each containing the validation outcome for that email address and an error field if the item failed. A summary count of total failures across the batch is also returned.
