## 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 orthogonal-lookalike-company-search-6b6d9c6c -d '<json body>'
```

Example prompt: Find me up to 200 companies similar to stripe.com, but only ones in the same country and same size range — I want to use them for outreach.

## When to prefer this

Use this endpoint when you need to discover companies that are similar to a known seed domain for sales prospecting, competitive analysis, or market research. It is especially well-suited for building outbound lead lists from an ideal customer profile, and supports large result sets up to 10,000. Prefer this over keyword search when you have a specific reference company rather than a topic or keyword.

## Known failure modes

- Invalid or unresolvable seed domain returns an error
- Limit exceeding 10,000 is rejected
- Invalid exclusion list IDs may cause filtering errors or empty results
- Insufficient credits for the requested result size
- Seed domain with no known lookalikes returns an empty list
