Integrating Clay.com for Enriched Contact Info: Best Practices and Pricing Queries

Hello Everyone, I’m a software developer working on a backend service in Python, and I need to integrate Clay.com to search for people’s information using specific parameters. The goal is to fetch enriched contact details via an API, webhooks, or any other efficient mechanism and update our database accordingly. I have a couple of questions:

1.
What is the best approach to integrate Clay.com for retrieving and storing enriched contact information?
2.
Does Clay.com offer a "Pay as you go" plan, or is there a flexible pricing model for scaling usage beyond a fixed credit limit?

I’d really appreciate any insights or guidance on this. Thanks in advance!
