## When to prefer this

Choose this endpoint when you need comprehensive B2B company intelligence from a single domain lookup, especially when you need a combination of contact emails, social profiles, tech stack signals, and pricing data in one call. Prefer it over generic web scrapers when you need structured, verified lead data for GTM, sales prospecting, or competitive research workflows.

## Known failure modes

- Domain not found or invalid — returns empty or error response
- Domain exists but has no detectable tech stack signals — partial results returned
- Unverifiable or non-existent email contacts — empty emails field
- Rate limiting or payment failure via x402 — 402 response requiring payment
- Private or heavily obfuscated domains may yield sparse results
