At least 1 credit per request even when nothing matches.\n\n## Before you call either\n\n### Clay\n\n1. Fetch GET /search/query-mode/reference before writing a search query\n2. Poll routine results until a terminal 200, since 202 means still running\n3. Expect HTTP 402 when a plan's search cap is hit, and tell the user the reset date\n4. Check GET /credits/balance before large batch runs\n5. Ask the user before enabling the plugin's auto-approve hook in a shared workspace\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, Clay or Lusha API + MCP?\n\nLusha API + MCP scores 62.3 (B) on agent readiness against Clay's 57.7 (C), and leads in 5 of 7 scored categories.
