How this service works
One account for your money. And a Copilot that only acts when you approve. Earn on savings, send money in seconds, and buy stocks from $1, all from one balance, with none of the crypto.
Output
A JSON object with a businesses array containing: business name, category and group, verified email with quality grade and source URL, phone number, full mailing address, inferred contact name, listing confidence score and last-updated date, website URL with live/closed status, and website signals including tech stack, copyright year, online booking platforms, and hiring status.
Example use cases
Identify caller before sales outreach
“I have a phone number, 4043552001, that came in as a warm lead — can you look up what business it belongs to and get me their email and address?”
Enrich CRM record from domain
“We have a new lead that came through with just their website, midtownfamilydental.com — can you find the business name, contact email, and mailing address behind it?”
Verify a vendor's legitimacy
“Before I pay this invoice, can you check what company is actually behind the website invoicingco.com and confirm their address and phone number match what they gave me?”
Technical details
Endpoint
GEThttps://api.liquidagent.ai/v1/leads/lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify or enrich a business record from just a US phone number or a website domain — particularly useful for sales prospecting, lead enrichment, vendor vetting, or reverse-lookup workflows where you need email, address, and contact details in a single call. Prefer it over generic WHOIS or public search tools when you need structured, confidence-scored business data with email quality grades and website signals.
Side effects
- No business found for the given phone or domain — found:false with count:0
- Invalid phone number format not matching any US number pattern
- Domain not crawlable or no associated business listing found
- Ambiguous input where both phone and domain are omitted
- Payment failure via x402 protocol resulting in 402 response before data is returned
