## 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-company-discover-via-locus-x402-690b5628 -d '<json body>'
```

Example prompt: Find me up to 20 private SaaS companies headquartered in San Francisco with 11-50 employees that use Salesforce — I'm building a prospecting list for outreach.

## When to prefer this

Use this endpoint when you need to discover and filter companies for B2B lead generation, prospecting, or market research — especially when filtering by industry, headcount, technology, or similarity to a known domain. Prefer this over generic web search when you need structured company data with enrichment fields ready for outreach workflows. Best suited for agents building sales pipelines, performing competitor analysis, or sourcing partnership targets.

## Known failure modes

- No companies match the provided filters — empty results returned
- Invalid headcount range format causes a validation error
- Query too broad returns maximum results without useful specificity
- Rate limiting or payment failure causes request rejection
- Similar-to domain not recognized returns empty or irrelevant results
