## 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-a6426eb5 -d '<json body>'
```

Example prompt: Find me professionals with Machine Learning skills based in San Francisco who have the headline 'AI Researcher' and have worked at companies in the software development industry — I just need a quick preview with their names, titles, and companies.

## When to prefer this

Use this endpoint when you need to quickly discover and filter professional profiles from the CoreSignal database before committing to fetching full profiles. It is ideal for building candidate lists, competitive intelligence, or talent mapping where you want lightweight summary data first. Prefer this over the full collect endpoint when you don't yet know which specific employee IDs you need.

## Known failure modes

- No matching profiles found for the given filters — returns empty results array
- Invalid filter field values may return 400 bad request
- Overly broad filters may return too many results with lower relevance
- Rate limiting or payment issues may return 402 or 429 errors
- Misspelled company names or skills may yield zero results

## 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 list of matching professional employee records, each containing: id (for fetching full profiles), full_name, headline, location, company, title, and a relevance score. Results are filtered based on provided criteria and ranked by relevance.
