Apollo API Integration

Hello, everyone!
I want to integrate the Apollo.io API to the site for the marketing.
But even though I use the organization plan, which is the biggest plan in Apollo, the access number to the API endpoint can’t exceed 200/min, 600/hour, 6000/day.
And each time the customer search for contacts, I have to access to the apollo api endpoint. According to the above, each customer cannot search more than 4 times per minute?
How can I deal with this?
Hope your kind help.🤝
