## 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 leadsforge-lookalike-company-search-999c6b89 -d '<json body>'
```

Example prompt: Find me 20 companies similar to stripe.com and shopify.com — filter for Series A or Series B companies in the US with between 50 and 500 employees, and show me the first page of results.

## When to prefer this

Use this endpoint when you need to discover companies that resemble a known set of seed companies — ideal for building prospect lists, doing competitive research, or finding TAM segments. It is preferable over keyword search when you have existing company domains and want structurally similar companies rather than keyword matches, and when you need filtering by geography, company size, funding stage, or category.

## Known failure modes

- Invalid or unresolvable domain in the domains array returns an empty or partial result set
- Unsupported location, category, or funding stage filter values may return an error or be ignored
- Exceeding page size limits may return a validation error
- No lookalikes found for niche domains returns an empty results array
- Payment failure (x402 protocol) prevents the call from completing
