## 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-enrichment-via-locus-x402-f847be53 -d '<json body>'
```

Example prompt: Can you enrich the contact profile for john.doe@acme.com — I need their company info, job title, and any other professional details Hunter has on them?

## When to prefer this

Choose this endpoint when you need to enrich a known email address or LinkedIn handle with professional and company context for B2B sales, outreach, or CRM purposes. It is ideal for per-contact, pay-as-you-go enrichment without a monthly subscription commitment, particularly when you have an email or LinkedIn handle as your starting point rather than just a name or company.

## Known failure modes

- Email address not found in Hunter database — returns empty or null data object
- Invalid email format provided — request rejected with validation error
- LinkedIn handle not recognized or not mapped to a contact — empty enrichment result
- Payment failure or insufficient USDC balance — 402 payment required error
- Rate limiting or quota exceeded on the Hunter backend — service temporarily unavailable
