Plan prices were not readable, the docs send API plan requests to email, the terms require a human account holder, and the `account` tool returns the account's API key to the model.\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### RocketReach API\n\n1. Search first with `person_search` or `company_search`, which cost no credits, then look up only the profile IDs needed\n2. Treat `status: \"pending\"` as normal. Poll `check_person_status` after at least 3 seconds, and polling is free\n3. Do not echo the `account` tool's output to users or logs. It includes the account's API key\n4. Send the key in the `Api-Key` header. The `api_key` query parameter is deprecated\n5. Bulk lookup takes 1 to 100 queries and needs a webhook. Results arrive at the webhook, signed in `X-RocketReach-Signature`\n6. Do not loop on `unknown` from `email_verify`, or on `lookup_failed` and `not_found`. The last two are terminal\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, RocketReach API or ZoomInfo API + MCP?\n\nZoomInfo API + MCP scores 72.2 (BB) on agent readiness against RocketReach API's 51.2 (D), and leads in 6 of 7 scored categories.\n\n### Do RocketReach API and ZoomInfo API + MCP need an API key?\n\nRocketReach API takes an API key or an OAuth sign-in. ZoomInfo API + MCP uses an OAuth sign-in.\n\n### Can an agent call RocketReach API and ZoomInfo API + MCP without installing anything?\n\nYes. RocketReach API has a hosted endpoint at https://api.rocketreach.co/api/v2 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/rocketreach-vs-zoominfo.json, and with the fewest tokens: https://www.anchorterminal.com/compare/rocketreach-vs-zoominfo.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"rocketreach\", \"b\": \"zoominfo\"}`.
