Before you call either

Coresignal API + MCP

  1. Search for IDs first (free), then collect only the records you need
  2. Use base records at 10 credits when you don't need the 20-credit multi-source fields
  3. Use MCP v2 at /mcp/v2. The older /mcp endpoint will be deprecated
  4. Treat a 402 as out of credits, not a transient error
  5. Expect no work emails for EEA and UK people from the MCP email tool

Lusha API + MCP

  1. Batch up to 25 contacts a request. A single bulk request costs 1 credit, not 1 per contact
  2. Ask for phones only when needed. A phone is 5 credits against 1 for an email
  3. Use the Buying Group endpoint. Decision Makers was retired on 2026-09-04
  4. Use /v3/lookalike/contacts for contact lookalikes
  5. Back off exponentially on 429. Free keys stop at 100 requests a day
