Description

Lusha’s API lets you search contacts and companies, then enrich chosen records with emails and phone numbers. Newer modules cover prospecting by filter, lookalikes, intent signals and fit scores.

Search results do not include emails or phones. You pass the returned contact ID to an enrich call, which spends credits. The same credit balance is shared with the web app, extension and MCP.

Good for teams that want Lusha data inside their own tooling. Check with Lusha which plan you need before you build.

Key endpoints

POST /v3/contacts/search: find contacts from known identifiers
POST /v3/contacts/enrich: reveal emails and phones by contact ID (up to 100 per call)
POST /v3/contacts/prospecting: find contacts that match filter criteria

Editor’s note What our review found

Editorial research, reviewed 23 Oct 2026. We read the vendor's pricing page and API docs. We did not run live calls. This listing is not an endorsement.

Cost: the pricing page shows a free plan with 40 credits a month and no card needed. Paid plans in USD, billed yearly: Starter $37.45/mo (4,800 credits a year), Pro $52.45/mo (7,200 credits a year), Premium $299.95/mo (40,800 credits a year), Scale is custom. The Pro card lists API (Premium lists API Advanced). The comparison table shows "Strict rate limits" on some lower plans, but it does not make clear which, so API access on Free and Starter is not confirmed. The docs say keys depend on your account and plan. Ask Lusha before buying for the API.

Credentials and data: one API key from the Lusha dashboard. Keep it server-side in an environment variable or secret manager, never in code or a plain-text file. The names and company domains you send go to Lusha. You receive personal emails and phone numbers, so GDPR and similar consent rules apply, especially for cold outreach.

Good to know: rate limits vary by plan with per-minute, hourly and daily windows, shown in response headers. The docs refer to a V3 API with a migration guide.
