## 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 domain-company-enricher-ai-firmographics-lead-scoring-api-59932169
```

Example prompt: Can you enrich this lead for me — their work email is john@stripe.com — and give me a lead score, industry, employee range, and whether they're B2B or B2C?

## When to prefer this

Use this endpoint when you need structured company intelligence from just a domain or work email, especially in sales automation, CRM enrichment, or lead scoring pipelines. Prefer it over generic web search when you need normalized, machine-readable firmographic output with a confidence score and B2B/B2C classification in a single call.

## Known failure modes

- Unknown or unresolvable domain returns low confidence score or empty fields
- Invalid email format may return an error or null result
- Newly registered domains may have no firmographic data available
- Private or personal domains (e.g. gmail.com) will not return company firmographics
- Rate limiting or payment failure (x402) results in 402 Payment Required response
