## 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-employee-search-preview-14cb73ed -d '<json body>'
```

Example prompt: Can you preview the Coresignal employee search results for software engineers at Google in the United States with senior-level seniority — I just want a summary of how many match and who they are before I do a full pull.

## When to prefer this

Use this endpoint when you want to validate filters and see a summary of matching employee records before committing to a full filter search. Ideal for scoping employee searches, estimating result volume, or quickly sampling the professional database without pulling all records. Prefer this over the full Filter endpoint when you need a lightweight, cost-effective first pass.

## Known failure modes

- Invalid or malformed filter parameters return a 400 error
- No matching professionals found returns an empty result set
- Missing required filter fields may return an error or unfiltered results
- Authentication failure returns 401 unauthorized
- Rate limiting or quota exceeded returns 429 error
- Overly broad filters may return too many results or a capped preview

## How this service works

Preview employee search results with summary data. Pass filters in the request body. Returns matching professionals with key fields: id, full_name, headline, location, company, title, and relevance score. Use the 'id' field with the 'Base Employee Collect by ID' endpoint to get full profiles.

## Output

Returns a preview of matching professional/employee records with summary data — including profile highlights such as name, title, company, location, and seniority — for professionals that match the supplied filters, without returning the full dataset.
