Lusha Prospect Tool

​

What it does

​

Key features

• Filter-based discovery over Lusha’s full B2B database (top of funnel — find the names)
• Person filters: department, seniority, country/location, required data points
• Company filters: size, revenue, location, industry, NAICS/SIC, technologies, intent topics
• Returns non-PII previews — no reveal credits spent on discovery
• Paginate up to 50,000 results per query
• Each match includes an id ready to pass to Lusha Enrich

​

Parameters

​

Common use cases

​

Find decision-makers at target-sized companies

entity_type: "contact"
contact_filters: { "departments": ["Finance"], "seniority": [9, 8] }
company_filters: { "sizes": [{ "min": 51, "max": 200 }] }
size: 25

​

Build a target-account list

entity_type: "company"
company_filters: { "industriesLabels": ["Construction"], "revenues": [{ "min": 10000000 }], "locations": ["Texas"] }

​

Page through a large result set

entity_type: "contact"
contact_filters: { "departments": ["Sales"], "countries": ["United States"] }
page: 1
size: 50

​

What you get back

• results[] — each preview includes id, name, jobTitle, company, location, has (available fields), and canReveal ([{ field, credits }])
• total_matches — total number of records matching the filters
• page / size — the page returned
• rate_limits — remaining requests for the minute/hour/day window

​

Best practices

• Prospect first, enrich second — discovery is cheap; only spend reveal credits on the subset worth contacting
• Start broad, then narrow — overly specific filters can return zero matches
• Use canReveal to see whether a match even has an email/phone before enriching
• Page deliberately — each page is a request that counts against rate limits

​

Troubleshooting

• Pass a non-empty filter object — see the keys in the Parameters table

• Loosen filters; combining many narrow constraints can eliminate all matches

• Slow down or wait for the window to reset — limits vary by plan
