## 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 email-verification-api-46f6c6ce
```

Example prompt: Can you verify whether the email address john.doe@example.com is real and deliverable — check if it has valid syntax, working MX records, and isn't a disposable or role account?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call email validation with no API key or account setup, especially in agent workflows requiring fraud screening, list hygiene, or pre-send deliverability checks. Prefer this over heavyweight email verification platforms when cost per call and simplicity matter.

## Known failure modes

- Missing or malformed email query parameter returns an error
- Domain has no MX records — mx_found returns false and deliverability_score may be 0
- Network timeout when querying remote MX servers
- Disposable email provider database may lag behind newly created throwaway domains
- Role account detection may produce false positives for legitimate shared inboxes

## How this service works

Live Steam best-sellers, deals, per-app detail and IGDB metadata, Twitch hype scores, and agent utilities for verification and extraction. From $0.001 a call, free samples on every endpoint, auth-then-capture. MCP and HTTP.

## Output

Returns a JSON object with: risk level (e.g. 'low'), whether MX records were found, whether the address is disposable, the MX provider name (e.g. 'Google Workspace'), whether it is a role account, whether syntax is valid, and a deliverability score from 0–100.
