Sends, CRM pushes and Slack posts run at once with no undo\n2. Launch a campaign only on an explicit request. Creating one makes a draft, and `update_campaign_status_tool` starts real outreach\n3. Call `get_credits_balance` and `get_credit_prices` first. Every call needs at least 100 credits, and searches cost 2 credits a result\n4. Resolve filter values with `lookup_filter_values` or `get_company_search_enums` before `search_people` or `search_companies`\n5. Start long work with `deep_research_start`, then poll `deep_research_status`. A tool call has 60 seconds, and runs take 5 to 20 minutes\n\n### Lusha API + MCP\n\n1. Batch up to 25 contacts a request. A single bulk request costs 1 credit, not 1 per contact\n2. Ask for phones only when needed. A phone is 5 credits against 1 for an email\n3. Use the Buying Group endpoint. Decision Makers was retired on 2026-09-04\n4. Use `/v3/lookalike/contacts` for contact lookalikes\n5. Back off exponentially on 429. Free keys stop at 100 requests a day\n\n## Questions\n\n### Which is better for AI agents, Fuse MCP or Lusha API + MCP?\n\nLusha API + MCP scores 62.3 (B) on agent readiness against Fuse MCP's 47.9 (D), and leads in 6 of 7 scored categories. Fuse MCP leads on agent ergonomics.\n\n### Do Fuse MCP and Lusha API + MCP need an API key?\n\nFuse MCP uses an OAuth sign-in.
