## When to prefer this

Use this endpoint when you need to search across many companies simultaneously using multiple filters such as industry, geography, funding stage, or funding amount. Prefer this over the single-company lookup endpoint when you don't have a specific company ID and need to discover companies matching certain criteria. Ideal for deal sourcing, competitive landscape research, or investor due diligence workflows.

## Known failure modes

- No companies match the specified filters, returning an empty result set
- Rate limiting or quota exceeded returns a 429 error
- Payment not processed results in an authorization failure
- Overly broad queries may return paginated results requiring additional calls
