Track Usage

from florentin import Florentin client =
      Florentin(api_key="sk_live_...") # Track API usage per customer response =
      client.usage.record( customer_id="cust_abc123", product_id="prod_gpt4_api", quantity=1500,
      unit="tokens", metadata={ "model": "gpt-4", "endpoint": "/v1/chat/completions" } )
      print(f"Usage recorded: {response.id}")

import { Florentin } from
      "florentin"; const client = new Florentin({ apiKey: "sk_live_..." }); // Track API usage per
      customer const response = await client.usage.record({ customerId: "cust_abc123", productId:
      "prod_gpt4_api", quantity: 1500, unit: "tokens", metadata: { model: "gpt-4", endpoint:
      "/v1/chat/completions" } }); console.log(`Usage recorded: ${response.id}`);

import
      "github.com/florentin/florentin-go" client := florentin.NewClient("sk_live_...") // Track API
      usage per customer response, err := client.Usage.Record(ctx, &amp;florentin.UsageParams{

Get Usage Summary

# Get usage summary for billing period summary =

      console.log(`Estimated cost: $${summary.estimatedCost}`);

// Get usage summary for
      billing period summary, err := client.Usage.GetSummary(ctx, &amp;florentin.SummaryParams{
      CustomerID: "cust_abc123", StartDate: "2026-01-01", EndDate: "2026-01-31", })
