Send a company name or website with every contact, or you get `only_contact_data`\n2. Send only documented fields. New accounts get a 400 for unknown ones\n3. Match webhook results by `request_id`, since order isn't guaranteed and duplicates happen\n4. Poll no faster than every 30 seconds, as the not-ready response asks\n5. Post an empty contact to read the credit balance at no cost\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, Dropcontact API + MCP or ZoomInfo API + MCP?\n\nZoomInfo API + MCP scores 72.2 (BB) on agent readiness against Dropcontact API + MCP's 50.9 (D), and leads in 6 of 7 scored categories.\n\n### Do Dropcontact API + MCP and ZoomInfo API + MCP need an API key?\n\nDropcontact API + MCP takes an API key or an OAuth sign-in. ZoomInfo API + MCP uses an OAuth sign-in.\n\n### Can an agent call Dropcontact API + MCP and ZoomInfo API + MCP without installing anything?\n\nYes.
