Verdicts

Lusha API + MCP

API key on every plan, including Free with 40 credits a month. At least 1 credit per request even when nothing matches.

ZoomInfo API + MCP

Search, lookup and similar-record calls cost no credits, and a free account with 1,000 data and 1,000 AI credits needs no card. OAuth carries 20 scopes and limits are published per package. The Licence Terms and Conditions bar disclosing benchmark results, and the two documentation sites disagree on batch sizes and rate-limit headers.

Before you call either

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

ZoomInfo API + MCP

  1. Call Lookup first and pass the returned IDs to Search. Unknown industry, metro or topic strings are rejected with a 422
  2. Search before Enrich. Search is free, and each newly enriched record costs one data credit
  3. Request only the scopes the task needs in the scope parameter of the token call. Omitting it grants every scope configured on the app
  4. On 429 read X-RateLimit-Rejected-Bucket and wait for Retry-After. An exhausted hourly window can mean a wait of several hundred seconds
  5. Turn off model training in the AI client before connecting the MCP server. ZoomInfo prohibits MCP data being used for training
