## 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 orthogonal-company-count-92ceeb75 -d '<json body>'
```

Example prompt: Before I run the full company search, can you check how many companies match my filters for SaaS companies in the US with 50-200 employees, excluding the companies in my exclusion list?

## When to prefer this

Use this endpoint when you need to estimate the number of results a company search will return before running the full search — especially useful for validating filter configurations, managing costs, or deciding whether to paginate. Prefer this over running a full search when you only need the result count, not the actual company records.

## Known failure modes

- Invalid or malformed searchParams object returns a 400 error
- Non-existent companyExclusionListIDs cause an error or are silently ignored
- Payment failure (x402) prevents the request from being processed
- Empty search params may return total company count or an error depending on API behavior
- Rate limiting may occur if called too frequently

## How this service works

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

## Output

A numeric count of companies that match the provided search parameters and exclusion filters, allowing the caller to gauge result volume before committing to a full (potentially more expensive) search query.
