## 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-combined-search-count-47602658 -d '<json body>'
```

Example prompt: Using Fiber AI, tell me how many companies and people match my search — I'm looking for Series B SaaS companies in the US with 50 to 500 employees and contacts who are VPs of Engineering.

## When to prefer this

Use this endpoint when you need to know the size of a result set before fetching the actual records — ideal for pagination planning, quota checking, or validating that search filters are narrow enough to be actionable. Prefer this over running a full search when you only need counts, not the underlying contact or company data.

## Known failure modes

- Invalid or malformed filter parameters return a 400 error
- Missing required filter fields cause validation errors
- Overly broad filters with no constraints may time out or return unexpectedly large counts
- Authentication errors return 401 if credentials are missing or invalid
- Rate limiting may return 429 if too many requests are sent in quick succession

## How this service works

Get total count of companies and people matching search filters in one call.

## Output

Returns an integer count of total companies and total people matching the supplied search filters, allowing the agent to understand result volume before committing to a full paginated fetch.
