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.\n\n**Explorium AgentSource.** AgentSource v2 has a public OpenAPI 3.1 file, Markdown docs, a 200 queries a minute limit with `Retry-After`, public credit prices and a 100-credit trial. No status page or published SLA was found, each company shares one API key with no scopes, and the vendor's two published price tables disagree.\n\n## Before you call either\n\n### Clearbit\n\n1. 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\n2. Replace logo.clearbit.com links, which stopped working after 8 December 2025\n\n### Explorium AgentSource\n\n1. Send the key in the `api_key` header to `https://api.explorium.ai` and use `/v2` paths. v1 is deprecated\n2. Point MCP clients at `https://mcp-v2.explorium.ai/mcp`. The site's agent files still name the v1 server at `mcp.explorium.ai`\n3. Count each entity in a batch as one query against the 200 a minute limit, so 50 IDs in one call spend 50\n4. Call the statistics endpoint first to size an audience for free. Fetch costs 1 credit a result, or 2 with the Bombora intent filter\n5. Call `/v2/autocomplete` before filtering on category, tech stack or job title, and never mix two category types in one request\n\n## Questions\n\n### Which is better for AI agents, Clearbit or Explorium AgentSource?\n\nExplorium AgentSource scores 48.1 (D) on agent readiness against Clearbit's 13.5 (F), and leads in 6 of 7 scored categories. Clearbit leads on transparency \u0026 trust.\n\n### Do Clearbit and Explorium AgentSource need an API key?\n\nBoth need an API key.\n\n### Can an agent call Clearbit and Explorium AgentSource without installing anything?\n\nNo hosted endpoint is listed for Clearbit. Explorium AgentSource has a hosted endpoint at https://api.explorium.ai.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/clearbit-vs-explorium-agentsource.json, and with the fewest tokens: https://www.anchorterminal.com/compare/clearbit-vs-explorium-agentsource.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"clearbit\", \"b\": \"explorium-agentsource\"}`.
