Manage Billing Cycles with the MCP Server
Need to know what's owed? You can check current billing status by calling `list_invoices`. This gives you a clear view of all pending and past bills. Agents also track usage history using `get_metrics`, letting your agent pinpoint exactly where consumption happened. Agents maintain full visibility over the financial side of things. They can list available rate cards with `list_rate_cards` or check an account's current balance using `get_wallet_balance`. This keeps billing logic predictable for Pydantic AI.
Process Usage Events via Type-Safe Tools
When something happens, you need to record it. The agent calls `ingest_event` when a single event occurs, requiring specific details like the schema name and timestamp. For bulk processing, use `ingest_batch_events` to handle large volumes of usage data efficiently. This process keeps your billing accurate because every response is validated. You'll want to ensure incoming events include account ID and dimensions so you can correctly attribute costs.
Maintain Customer Records with Pydantic AI
Your agent needs to manage who's paying. Use `list_accounts` to see all existing accounts, or call `create_account` for a new user. Updates are handled by the `update_customer` tool when details change. The system also lets you confirm feature access using `check_entitlement`. If the account needs more funds, your agent can quickly call `grant_credit`.
