It is backed by CrustData's structured company dataset and is ideal for B2B prospecting, competitive analysis, and market research. Prefer this over general web search when you need structured, filterable company data rather than unstructured text results.

## Known failure modes

- No companies match the given filters, returning an empty result set
- Payment failure via x402 protocol if USDC balance is insufficient
- Rate limiting if too many requests are made in a short period
- Overly broad filters may return truncated or paginated results
