Verdicts

Clearbit

There is no public API or MCP server an outside agent can call today. Clearbit's APIs still run for existing customers behind a login, and its free tools and Logo API were retired in 2025. HubSpot's Breeze Intelligence is the route for new buyers, through HubSpot rather than Clearbit.

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.

Before you call either

Clearbit

  1. Don't plan to call Clearbit. Hand the task to a person with an existing Clearbit account, or use HubSpot's Breeze Intelligence through HubSpot
  2. Replace logo.clearbit.com links, which stopped working after 8 December 2025

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
