## 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 tomba-email-verifier-via-vaaya-4962f355 -d '<json body>'
```

Example prompt: Before I send to john.doe@acmecorp.com, can you verify whether that email is actually deliverable — check SMTP, MX records, and flag it if it's disposable or risky?

## When to prefer this

Use this endpoint when you have a single email address you need to validate before sending or storing — especially after discovering an email via a finder tool like Tomba LinkedIn email reveal. It is the cheapest verification tier and is ideal as a pre-send gate to avoid bounces and protect sender reputation. Prefer this over full enrichment endpoints when all you need is deliverability confidence rather than full contact data.

## Known failure modes

- Invalid or malformed email address returns validation error
- Domain with no MX records returns undeliverable status
- SMTP server timeout or unreachable host may return risky status rather than a definitive result
- Missing required email parameter returns a 400-level error
- API quota exceeded or authentication failure returns error response

## How this service works

Verify an email address's deliverability via Tomba. Pass `email`. Returns status (deliverable/undeliverable/risky), SMTP + MX checks, disposable/webmail flags, and a score. Cheapest verify rung — use before sending to a found email.

## Output

Returns a deliverability status (deliverable, undeliverable, or risky), results of SMTP and MX record checks, boolean flags for disposable and webmail addresses, and a numeric deliverability confidence score.
