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**LeadMagic API + MCP.** RFC 9457 problem-details errors with `request_id`, and Retry-After on 429. No free tier or trial credits, plans from $99 a month.\n\n## Before you call either\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### LeadMagic API + MCP\n\n1. Call `preview_cost` before bulk work. It's free\n2. Read `X-Credits-Remaining` after each call instead of polling the balance\n3. Treat 402 as out of credits and wait out Retry-After on 429\n4. Keep credit-free search under 13,333 calls a day per account\n5. Retry `unknown` validations later. They cost nothing\n\n## Questions\n\n### Which is better for AI agents, Explorium AgentSource or LeadMagic API + MCP?\n\nLeadMagic API + MCP scores 60.2 (C) on agent readiness against Explorium AgentSource's 48.1 (D), and leads in 5 of 7 scored categories. Explorium AgentSource leads on payments \u0026 pricing.\n\n### Do Explorium AgentSource and LeadMagic API + MCP need an API key?\n\nExplorium AgentSource needs an API key. LeadMagic API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Explorium AgentSource and LeadMagic API + MCP without installing anything?\n\nYes. Explorium AgentSource has a hosted endpoint at https://api.explorium.ai and LeadMagic API + MCP at https://api.leadmagic.io.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/explorium-agentsource-vs-leadmagic.json, and with the fewest tokens: https://www.anchorterminal.com/compare/explorium-agentsource-vs-leadmagic.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"explorium-agentsource\", \"b\": \"leadmagic\"}`.
