Automatically track OpenAI API consumption, generate weekly spending reports, and update budget spreadsheets. Essential for companies with growing AI integration costs.

Workflow Steps

1

OpenAI API

Fetch usage data

Use OpenAI's Usage API endpoint to retrieve daily API consumption data including tokens used, requests made, and costs by model (GPT-4, GPT-3.5, etc.). Set up automated daily pulls of this data using the organization's API key.

2

Zapier

Process and format data

Create a Zapier automation that runs daily, fetches OpenAI usage data, and formats it into structured records. Calculate running totals, daily averages, and month-to-date spending. Add formulas to project end-of-month costs based on current usage trends.

3

Google Sheets

Update budget tracker

Configure Zapier to append daily usage data to a Google Sheets budget tracker. Include conditional formatting to highlight when spending exceeds 80% of monthly budget. Set up auto-generated charts showing usage trends and cost breakdowns by AI model and application.
