Export API Key Usage

API endpoint to export usage and cost by API key

This endpoint exports API usage grouped by API key for the selected period. Results include workspace and personal API keys.

Before You Start

Prerequisites and rate limits: See the Usage Export API overview.
Browser requests: ajan intentionally blocks browser-origin requests to protect your API key. Use API keys server-side and store them securely. See API Key Best Practices.
