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**Prospeo API + MCP.** MCP tool descriptions say when to use each tool, its credit cost and the next call. No status page, SLA or changelog.\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### Prospeo API + MCP\n\n1. Call `search_suggestions` before using location, technology or industry filters, or the search returns nothing\n2. Pass `person_id` values from search into `bulk_enrich_person`, 25 at a time\n3. Branch on the body `error_code`, not the HTTP status, which is 400 for most failures\n4. Set `enrich_mobile` only when needed. A mobile costs 10 credits against 1 for an email\n5. Use Enrich Person. The old Email Finder endpoint was removed in March 2026\n\n## Questions\n\n### Which is better for AI agents, Explorium AgentSource or Prospeo API + MCP?\n\nProspeo API + MCP scores 50.9 (D) on agent readiness against Explorium AgentSource's 48.1 (D), and leads in 3 of 7 scored categories. Explorium AgentSource leads on reliability, schema \u0026 documentation and transparency \u0026 trust.\n\n### Do Explorium AgentSource and Prospeo API + MCP need an API key?\n\nExplorium AgentSource needs an API key. Prospeo API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Explorium AgentSource and Prospeo API + MCP without installing anything?\n\nYes. Explorium AgentSource has a hosted endpoint at https://api.explorium.ai and Prospeo API + MCP at https://api.prospeo.io.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/explorium-agentsource-vs-prospeo.json, and with the fewest tokens: https://www.anchorterminal.com/compare/explorium-agentsource-vs-prospeo.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"explorium-agentsource\", \"b\": \"prospeo\"}`.
