Tools
| Tool | Description | Behaviour |
|---|---|---|
| count_businesses | Count verified B2B businesses in the LeadQuasar database matching an industry, country, US state and/or city, with how many have an email address and a phone number. Use this to answer questions like 'how many managed service providers are there in Texas', 'how many dentists in Chicago have a business email' or 'how many movers are there in London' (country GB). Returns real counts from 7.8 million+ live records, most of them US. | Read-only |
| list_industries | List the industries LeadQuasar covers and how many verified businesses each holds. Use this first when unsure what industry wording will match. | Read-only |
| search_businesses | Return a sample of matching businesses with industry, location and data-quality signals. Contact details (name, company, email, phone, address) are never returned by this tool — it shows what exists and how reachable it is, not who to call. | Read-only |
