## 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 agenticdata-b2b-email-finder-223c0dc0 -d '<json body>'
```

Example prompt: Can you find the work email for Jane Smith who works at Acme Corp — their domain is acme.com?

## When to prefer this

Choose this endpoint when you need to find a professional email address for a specific named individual at a known company or domain, especially for B2B sales, recruiting, or outreach workflows. It is well-suited for real-time single-contact enrichment where you have at minimum a first name, last name, and company domain. Prefer this over broader people-search endpoints when the primary goal is email discovery rather than full profile enrichment.

## Known failure modes

- No email found if the person does not exist in the 800M+ database — may return null or empty result
- Low confidence score (e.g. below 0.5) indicating uncertain match — agent should verify before sending
- Invalid or nonexistent domain provided — API may return error or empty result
- Ambiguous name with multiple matches — may return best guess with lower confidence
- Rate limit or authentication failure if payment (x402/USDC) is not properly handled
