## 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 tuski-email-validation-job-creator-35ae1618 -d '<json body>'
```

Example prompt: Can you validate this list of emails for me — ['alice@example.com', 'bob@gmal.com', 'throwaway@mailinator.com'] — and tell me which ones are deliverable, which are disposable, and which look like typos?

## When to prefer this

Choose this endpoint when you need to validate a batch of email addresses at once rather than one at a time, especially for mailing list hygiene, CRM cleanup, or lead list scrubbing. It is well-suited for scenarios where you have a CSV export or an array of emails and want to distinguish valid, unreachable, disposable, and typo-domain addresses in a single job. The pay-per-use x402 micropayment model (with free processing for bad addresses) makes it cost-effective for large lists with expected high invalid rates.

## Known failure modes

- Both emails and csv_text provided simultaneously — API expects exactly one input type
- Neither emails nor csv_text provided — request will fail validation
- Malformed email format in the array — individual addresses may be flagged or cause job creation failure
- Payment failure via x402 protocol — job not created if USDC payment cannot be processed
- Empty email list or empty CSV — job may be created with zero billable addresses but no useful output
- Polling job ID for a job that has not yet completed — returns in-progress status rather than results

## How this service works

Create an email validation job from a JSON list of addresses or CSV text (send exactly one). Poll its status, then fetch results as JSON or CSV. Billing counts only testable addresses, fixed at creation; unreachable, disposable and typo domains are free.

## Output

Returns a job object with a unique job ID that can be polled for status. Once complete, results are available as JSON or CSV and include per-address verdicts indicating whether each email is valid/deliverable, unreachable, from a disposable domain, or contains a typo domain. Billing is fixed at job creation and only counts testable addresses; disposable, typo, and unreachable addresses are free.
