Keys have no scopes, the Claude Code plugin auto-approves most CLI calls, and the privacy policy dates from 2020.\n\n**ZoomInfo API + MCP.** Search, lookup and similar-record calls cost no credits, and a free account with 1,000 data and 1,000 AI credits needs no card. OAuth carries 20 scopes and limits are published per package. The Licence Terms and Conditions bar disclosing benchmark results, and the two documentation sites disagree on batch sizes and rate-limit headers.\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### ZoomInfo API + MCP\n\n1. Call Lookup first and pass the returned IDs to Search. Unknown industry, metro or topic strings are rejected with a 422\n2. Search before Enrich. Search is free, and each newly enriched record costs one data credit\n3. Request only the scopes the task needs in the `scope` parameter of the token call. Omitting it grants every scope configured on the app\n4. On 429 read `X-RateLimit-Rejected-Bucket` and wait for `Retry-After`. An exhausted hourly window can mean a wait of several hundred seconds\n5. Turn off model training in the AI client before connecting the MCP server. ZoomInfo prohibits MCP data being used for training\n\n## Questions\n\n### Which is better for AI agents, Clay or ZoomInfo API + MCP?\n\nZoomInfo API + MCP scores 72.2 (BB) on agent readiness against Clay's 57.7 (C), and leads in 6 of 7 scored categories.\n\n### Do Clay and ZoomInfo API + MCP need an API key?\n\nClay takes an API key or an OAuth sign-in. ZoomInfo API + MCP uses an OAuth sign-in.\n\n### Can an agent call Clay and ZoomInfo API + MCP without installing anything?\n\nYes. Clay has a hosted endpoint at https://api.clay.com/public/v0 and ZoomInfo API + MCP at https://api.zoominfo.com/gtm.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/clay-vs-zoominfo.json, and with the fewest tokens: https://www.anchorterminal.com/compare/clay-vs-zoominfo.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"clay\", \"b\": \"zoominfo\"}`.
