## 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-email-count-via-locus-x402-af3ae3fe -d '<json body>'
```

Example prompt: How many email addresses does Hunter have on record for stripe.com — and can you break it down by personal emails only?

## When to prefer this

Use this endpoint when you need a lightweight, low-cost check of how many emails Hunter has indexed for a domain or company before committing to a full email search or domain search. It's ideal for pre-qualifying outreach lists, estimating database coverage, or filtering companies worth targeting without paying for full contact details.

## Known failure modes

- Domain or company not found in Hunter database — returns empty or zero count
- Invalid email type filter value (must be 'personal' or 'generic') — may return error
- Missing both domain and company fields — request may fail validation
- Domain exists but has no indexed emails — returns zero count
- Payment failure or insufficient USDC balance — transaction not completed

## How this service works

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

## Output
