## 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 avedaris-email-domain-check-92dc8b7a -d '<json body>'
```

Example prompt: Can you check whether the email domain for john.smith@acme-corp.io is real and capable of receiving mail — does it have MX records and is the mailbox verified?

## When to prefer this

Use this endpoint when you need lightweight, real-time email domain validation before sending messages, registering users, or processing leads. It is well-suited for pre-screening email addresses at the point of collection, fraud detection on sign-up flows, or enriching contact data. Prefer this over full SMTP probing when you need a fast, low-cost signal about domain health without triggering spam filters. It is not a full mailbox verification service and may not catch all disposable email providers.

## Known failure modes

- Malformed email address returns validation error
- DNS lookup timeout for slow-responding domains
- Domain exists but has no public MX records, returning hasMx: false
- Mailbox verification may be blocked by mail servers that reject VRFY probes, leaving mailboxVerified: false even for valid addresses
- Network errors reaching DNS resolvers

## How this service works

AveDaris is the economic coordination layer for autonomous software: discover, route, evaluate, procure, verify, and learn across agent services.

## Output

Returns a JSON object containing: whether the domain has MX records (hasMx: boolean), the parsed domain name (domain: string), whether the specific mailbox was verified (mailboxVerified: boolean), and whether the domain has an A/address record (hasAddressRecord: boolean).
