Keys have no scopes, the Claude Code plugin auto-approves most CLI calls, and the privacy policy dates from 2020.\n\n**Enrich Layer API + MCP.** Pay-as-you-go credits from $10, non-expiring unless idle for 18 months. Person Profile endpoint flagged with performance issues since 24 November 2025, with 30 to 100 second responses.\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### Enrich Layer API + MCP\n\n1. Top up once before testing. Trial keys run at 2 requests a minute\n2. Set the person profile timeout to at least 100 seconds\n3. Ask for `extra`, personal emails or phone numbers only when needed, since each adds credits\n4. Use `callback_url` on slow lookups such as work email instead of holding the connection\n5. Map old Proxycurl paths with the transition guide rather than guessing\n\n## Questions\n\n### Which is better for AI agents, Clay or Enrich Layer API + MCP?\n\nClay scores 57.7 (C) on agent readiness against Enrich Layer API + MCP's 55.8 (C), and leads in 4 of 7 scored categories. Enrich Layer API + MCP leads on reliability and payments \u0026 pricing.\n\n### Do Clay and Enrich Layer API + MCP need an API key?\n\nClay takes an API key or an OAuth sign-in. Enrich Layer API + MCP needs an API key.\n\n### Can an agent call Clay and Enrich Layer API + MCP without installing anything?\n\nYes. Clay has a hosted endpoint at https://api.clay.com/public/v0 and Enrich Layer API + MCP at https://enrichlayer.com/api/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/clay-vs-enrich-layer.json, and with the fewest tokens: https://www.anchorterminal.com/compare/clay-vs-enrich-layer.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"clay\", \"b\": \"enrich-layer\"}`.
