Score Breakdown
⚙ Agent Friendliness
🔒 Security
GDPR and CCPA compliant. EU data processing. TLS enforced. No SOC2 documentation. API key with no scope granularity. Agents must ensure lawful basis for B2B contact data use.
⚡ Reliability
Best When
Your agent needs reliable B2B contact data (email + phone) for outbound sales with higher mobile phone coverage than competitors.
Avoid When
You need consumer contact data or very high volume (millions) enrichment — use ZoomInfo or PeopleDataLabs for scale.
Use Cases
- • Agents enriching CRM leads with verified email addresses and direct phone numbers via Lusha's contact API
- • Outbound prospecting automation — agents finding contact info for target companies' decision-makers at scale
- • CRM hygiene — agents validating and updating stale contact information in existing databases
- • SDR workflow automation — agents pulling verified prospect data into sales sequences automatically
- • Account-level enrichment — agents fetching company technographic and firmographic data for ICP scoring
Not For
- • Consumer contact data — Lusha is B2B focused; personal contact data collection may violate GDPR
- • High-volume bulk enrichment without API plan — free tier credits are limited
- • Real-time enrichment during live user interactions — Lusha API latency is not sub-100ms
Interface
Authentication
API key from Lusha developer portal. Passed in api_key header. Account-level key — no scope granularity. Monthly credit limits apply.

Agent Metadata
Known Gotchas
- ⚠ Each API call consumes a credit even for not-found results — agents should de-duplicate before calling
- ⚠ Contact data is sourced from Lusha's network — not real-time; some data may be months old
- ⚠ LinkedIn URL is the most reliable lookup identifier — email-based lookups have lower hit rates
- ⚠ GDPR compliance requires lawful basis for contacting EU residents — Lusha provides data but agents are responsible for compliance
- ⚠ Bulk enrichment API has different endpoint and higher minimum credit requirements than single-contact API
