Perplexity

Create searchable deal history indexes.

You call `get_deal_details` to pull data for a specific opportunity. This function's output becomes part of the indexed knowledge store. Later, your agent can query past sessions or configurations and get answers grounded in that live Zendesk Sell API data, not just general training.

Index current contact lists for RAG.

Need to know about all qualified prospects? You use `list_sales_contacts`. This entire list gets indexed into a vector store. This means you can query your knowledge base and ask, 'Which contacts were listed last week?' and get an answer based on the actual API data.

Build lead tracking context.

When you execute `create_new_lead`, that resulting record is indexed. You don't just write it; you add it to your searchable knowledge base. This lets you query the history of leads, retrieving details about accounts that were created weeks ago for follow-up context.
