Working Capital Ratios API

Retrieve working capital efficiency ratios for any publicly traded company. This endpoint returns turnover metrics and the cash conversion cycle that measure how effectively a company manages its receivables, inventory, and payables to fund day-to-day operations.

Working capital ratios reveal the operational efficiency of a business. A company that collects receivables quickly, turns inventory efficiently, and manages payable terms strategically will have a shorter (or even negative) cash conversion cycle, meaning it needs less capital tied up in operations. Companies like Apple famously operate with negative cash conversion cycles, effectively funding operations with supplier capital. These metrics are especially valuable for comparing operational efficiency across competitors and identifying companies that generate cash more efficiently from their asset base.

Data is available for both annual and quarterly periods, with up to 250 historical periods per request.
