## 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 oneshotagent-email-enrichment-validation-bfbe8f73 -d '<json body>'
```

Example prompt: Can you enrich and validate the email address john.smith@acme.com — I need to know if it's deliverable and any profile or identity details associated with it?

## When to prefer this

Use this endpoint when you need both enrichment (identity/profile metadata) and validation (deliverability check) in a single call for a given email address, especially in outreach, lead qualification, or CRM hygiene workflows. Prefer this over a pure deliverability-check sibling endpoint when you also need to know who is behind the email, not just whether it can receive mail.

## Known failure modes

- Invalid email format — input fails RFC 5321/5322 validation
- Email domain does not exist — returns undeliverable or unknown status
- Email address not found in enrichment database — sparse or empty enrichment result
- Rate limit or payment failure — 402/429 response if USDC payment is missing or quota exceeded
- Network timeout — service unavailable or slow upstream enrichment provider
