Perplexity

Connect BigQuery data to active checkouts via Google ADK

Feed your enterprise data warehouse metrics directly into your Gemini agent. The Google ADK allows your LLM to analyze customer usage patterns in BigQuery and immediately generate targeted purchase links using `create_checkout`. Since Gemini supports massive context windows, you can pass entire customer purchase histories to the agent. The agent then calls `list_products` and `get_variant` to find the exact upgrade option that fits their usage profile.

Automated subscription audit pipelines

Run scheduled batch audits on your recurring revenue directly inside Vertex AI. Your agent can run `list_subscriptions` and `list_subscription_invoices` to pull thousands of records into its context window for discrepancy checks. If the agent detects an unpaid account that should have been downgraded, it executes `update_subscription` to correct the status. This keeps your database in sync with your actual revenue platform without manual developer scripts.

Large-scale store management via MCP Server

Manage your digital downloads and store configurations using natural language. The agent can read and organize your store assets by calling `list_files` and `get_file` to ensure your customers always get the correct download links. You can also track store metadata across multiple regional locations. Using `list_stores` and `get_store`, your enterprise agent can compile performance reports and update store settings on Google Cloud.
