Lusha API v3

Lusha's data and intelligence layer is built to run underneath your own systems and agents. The new Lusha API gives every contact and company a stable ID, so you can chain search, filtering, enrichment, signals and lookalikes on the same records without them shifting between calls.

What it is

The new Lusha API (v3) rethinks how the API works. Every contact and company has a stable Lusha ID you can pass from one call to the next. Search a list, filter it, then enrich it or pull signals and lookalikes on the same IDs. It also adds new premium fields and richer standard company data.

  • Stable IDsEvery contact and company keeps one Lusha ID you can reuse across calls.
  • Building blocksSearch, filter, then enrich, pull signals or find lookalikes with the same IDs.
  • New premium fieldsCompetitors, plus employees by department, location and seniority.
  • Richer company dataBusiness model, company email and phone, location zip codes, keywords and extra descriptions.

Good to know

Legacy numeric IDs are still accepted during the transition to v3. Premium fields use credits only when you reveal them. Some data returned by v2 endpoints appears in v3 under different field names, so check the API reference when you migrate.
