Keys have no scopes, the Claude Code plugin auto-approves most CLI calls, and the privacy policy dates from 2020.\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### Clay\n\n1. Fetch GET /search/query-mode/reference before writing a search query\n2. Poll routine results until a terminal 200, since 202 means still running\n3. Expect HTTP 402 when a plan's search cap is hit, and tell the user the reset date\n4. Check GET /credits/balance before large batch runs\n5. Ask the user before enabling the plugin's auto-approve hook in a shared workspace\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, Clay or Explorium AgentSource?\n\nClay scores 57.7 (C) on agent readiness against Explorium AgentSource's 48.1 (D), and leads in 6 of 7 scored categories. Explorium AgentSource leads on payments \u0026 pricing.\n\n### Do Clay and Explorium AgentSource need an API key?\n\nClay takes an API key or an OAuth sign-in. Explorium AgentSource needs an API key.\n\n### Can an agent call Clay and Explorium AgentSource without installing anything?\n\nYes. Clay has a hosted endpoint at https://api.clay.com/public/v0 and Explorium AgentSource at https://api.explorium.ai.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/clay-vs-explorium-agentsource.json, and with the fewest tokens: https://www.anchorterminal.com/compare/clay-vs-explorium-agentsource.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"clay\", \"b\": \"explorium-agentsource\"}`.
