## 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 hunter-via-locus-x402-combined-email-company-enrichment-d29e14d3 -d '<json body>'
```

Example prompt: Can you look up everything you can find on the contact behind john.smith@acme.com — verify the email, get their job title, and pull in company details for outreach?

## When to prefer this

Choose this endpoint when you need a single API call that combines both email verification and company/contact enrichment in one shot, rather than calling separate verify and enrich endpoints. It is ideal for sales and marketing automation workflows where you have an email address and want a full professional profile. Prefer this over raw Hunter.io direct access when you want pay-per-use USDC micropayment billing via the x402 protocol without managing a Hunter API subscription.

## Known failure modes

- Email address not found in Hunter database — data object may be empty or sparse
- Invalid email format causes input validation failure
- Email domain does not exist or is unresolvable — verification returns invalid status
- Hunter.io upstream rate limit or outage causes timeout
- Insufficient USDC balance or x402 payment authorization failure prevents the call from completing
- Newly registered or very obscure domains may return no company enrichment data

## How this service works

Email finding, verification, and company enrichment for outreach and lead generation.

## Output

Returns a JSON object containing email verification results (deliverability, format validity), professional contact details (name, job title, seniority, department), and company enrichment data (company name, domain, industry, size, location) sourced from Hunter.io, along with x402 payment metadata confirming the settled USDC amount.
