## 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-natural-language-company-search-8887dc95 -d '<json body>'
```

Example prompt: Find me Series A startups in the USA in the fintech space with between 50 and 200 employees — return the first 10 results.

## When to prefer this

Choose this endpoint when you need to discover companies using flexible, human-readable criteria like 'Series A startups in the US with 50–200 employees' rather than manually specifying structured filter fields. It is especially useful for exploratory research, lead generation, or market mapping where the exact filter taxonomy is unknown. Prefer the sibling structured-filter endpoint if you already have precise industry codes, exact headcount numbers, or founding year ranges and want deterministic filtering without NL interpretation overhead.

## Known failure modes

- Ambiguous or very broad queries may return low-relevance results
- Changing any non-pagination filter parameter starts a new billable request at $0.54
- Missing or invalid cursor may cause pagination errors
- Query terms that don't map to known industries or funding stages may return empty results
- Rate limiting or payment failure may block the request

## How this service works

Takes free-form text (e.g., 'Series A startups in USA with 50–200 employees') and returns a list of matching companies.           The endpoint interprets natural language queries and applies structured filters such as industries, funding stages, headcount ranges, and locations to identify relevant companies. Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

## Output

Returns a paginated list of companies matching the natural language query, including structured company details such as name, industry, funding stage, headcount range, and location, along with a pagination cursor and a billing requestId for free continuation pages.
