Api Endpoint

Liquid Leads lookup: the business behind a phone number or website

Who is this phone number or website? Give a US phone number or a website and get the local business behind it: name, address, category, the best email graded A/B/C, a contact name when the email shows one, socials and buying signals. A website only matches when it carries the business's own phone number, so the answer is never a guess. $0.01 per lookup that finds a business; no match, no charge. USDC on Base or Arc.
