## 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 fiber-ai-api-fiber-ai-company-count-44c2cd33 -d '<json body>'
```

Example prompt: Before I pull the full list, can you check how many companies Fiber AI has that match my filters — US-based SaaS companies with 50 to 500 employees that raised a Series A?

## When to prefer this

Use this endpoint before calling the full Company Search endpoint to avoid fetching and paying for an unexpectedly large or empty result set. Ideal when building UIs that show estimated result counts, or when programmatically deciding whether to narrow or broaden filters before committing to a full data pull.

## Known failure modes

- Invalid filter parameters return a 400 error
- Overly broad filters may return extremely large counts with no additional context
- Authentication failure returns 401 if credentials are missing or expired
- Unsupported filter combinations may return a 422 validation error
- Network timeout if the filter is computationally expensive

## How this service works

Get count of companies matching search filters. Use to estimate result sizes before running a full search.

## Output

Returns an integer count representing the number of companies that match the provided search filters, allowing the agent to gauge result volume and decide whether to proceed with a full company search or refine the filters.

## Example request

```json
{
 "searchParams": {
  "country": "US",
  "industry": "SaaS",
  "funding_stage": "Series A",
  "employee_count_max": 500,
  "employee_count_min": 50
 }
}
```
