# is-yandex-address

> is-yandex-address is a paid API for AI agents from email.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Checks whether an email address belongs to a Yandex consumer mailbox domain (yandex.com, yandex.ru, ya.ru) and classifies it as personal vs. business.

## 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 is-yandex-address-be6b4fe1
```

Example prompt: Can you check whether user@yandex.ru is a personal Yandex webmail address or a business email?

## When to prefer this

Use this endpoint when you need a cheap, fast, single-call check specifically for Yandex consumer domains. Prefer this over a generic free-email checker when your CRM or lead rules need precise Yandex-specific detection (yandex.com, yandex.ru, ya.ru) with a personal/business flag. For bulk checking of many emails at once, look for the bulk variant of this endpoint.

## Known failure modes

- Missing or malformed email address input returns an error
- Unknown or unsupported domain returns a negative match rather than an error
- Network timeout results in no classification
- Subdomains or custom domains hosted on Yandex infrastructure may not be detected

## How this service works

Is this a yandex address (yandex.com, yandex.ru, ya.ru)? Matches the domain part against yandex's consumer mailbox domains and reports personal-vs-business, so CRM and lead rules can treat free-webmail signups differently. $0.01 per check.

## Output

Returns a boolean indicating whether the email domain matches a known Yandex consumer mailbox domain (yandex.com, yandex.ru, ya.ru), along with a personal-vs-business classification to help downstream CRM or lead-scoring rules treat free-webmail signups differently.
