No free tier or trial credits, plans from $99 a month.\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### LeadMagic API + MCP\n\n1. Call `preview_cost` before bulk work. It's free\n2. Read `X-Credits-Remaining` after each call instead of polling the balance\n3. Treat 402 as out of credits and wait out Retry-After on 429\n4. Keep credit-free search under 13,333 calls a day per account\n5. Retry `unknown` validations later. They cost nothing\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, LeadMagic API + MCP or ZoomInfo API + MCP?\n\nZoomInfo API + MCP scores 72.2 (BB) on agent readiness against LeadMagic API + MCP's 60.2 (C), and leads in 6 of 7 scored categories.
