## 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 coresignal-company-search-preview-a11db27f -d '<json body>'
```

Example prompt: Can you preview a Coresignal company search for software companies in the United States with 50 to 500 employees — I just want to see how many match and get summary info before doing the full pull.

## When to prefer this

Use this endpoint when you want to validate your company search filters and get a lightweight preview of matching results before committing to a full filter search. Ideal for scoping the size of a result set, checking filter validity, or getting summary company data without retrieving full profiles. Prefer this over the full Filter endpoint when you only need summary data or want to estimate result volume first.

## Known failure modes

- Invalid or malformed filter parameters return a 400 error
- No companies match the provided filters, returning an empty result set
- Authentication failure returns a 401 unauthorized error
- Rate limit exceeded returns a 429 error
- Server-side error returns a 500 response

## How this service works

Preview company search results with summary data. Pass filters in the request body. Returns matching companies with key fields: id, name, website, industry, size, country, and relevance score. Use the 'id' field with the 'Base Company Collect' endpoint to get full profiles.

## Output

Returns an array of matching company records with key summary data fields such as company name, industry, location, employee count, and website, along with metadata indicating how many total results match the applied filters.
