## When to prefer this

Use this endpoint when you need to discover or prospect companies based on structured attributes like industry, location, employee count, or funding stage. Prefer this over free-text natural language company search when you have specific structured filter criteria. Ideal for building targeted B2B prospect lists or enriching sales pipelines.

## Known failure modes

- No companies match the provided filters — returns empty results list
- Invalid filter values (e.g. unsupported industry enum) — returns 400 validation error
- Authentication failure — returns 401 unauthorized
- Rate limit exceeded — returns 429 too many requests
- Overly broad filters returning too many results — may be truncated or paginated

## How this service works

Search for companies using filters Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

## Output

A list of companies matching the specified filters, each including details such as company name, domain, LinkedIn URL, industry, employee count, funding stage, and location.
