## 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 vaaya-prospeo-email-verifier-2eeacad4 -d '<json body>'
```

Example prompt: Can you verify whether john.smith@acmecorp.com is a real, deliverable email address before I add it to my outreach list?

## When to prefer this

Choose this endpoint when you need quick, pay-per-use email verification without setting up your own Prospeo account or API key. Ideal for agents running go-to-market or outreach workflows on Vaaya's platform where you want to validate individual email addresses on demand at $0.05 per check.

## Known failure modes

- Invalid email format returns validation error
- Unreachable mail server may result in unknown/timeout status
- Catch-all domains may return inconclusive results
- Payment failure (insufficient USDC balance) blocks the call
- Rate limiting if called too frequently in succession

## How this service works

Verify an email address's deliverability via Prospeo (rides enrich-person with an email input — the 2026 API has no standalone verifier). Pass `email`. The response's `person.email.status` is the verdict (e.g. VERIFIED) with `verification_method`. 1 credit per found email; no vendor charge on a miss; results cached 90 days upstream.

## Output

Returns a verification result indicating whether the email address is valid and deliverable, including status details such as whether the mailbox exists, is reachable, or is flagged as invalid, disposable, or a catch-all domain.
