Cloudflare launches Billable Usage API for programmatic cost visibility

Programmatic Cost Visibility

Cloudflare has launched a new Billable Usage API for self-serve accounts. This API provides a single endpoint to retrieve an account's usage and cost data, broken down by product and service period. It is designed to offer programmatic access to billing information, catering to automated systems and FinOps toolchains.

Comprehensive Product Coverage

The API covers all usage-based Cloudflare products, including Workers, R2, D1, Workers AI, Vectorize, Images, and Stream, through a single API call. This consolidation simplifies the process of gathering cost data across various services within a Cloudflare account.

API Details and Data Structure

The API returns data in a JSON format, with each row representing a charge period for a specific product. Key fields include `ServiceName`, `ServiceFamilyName`, `ChargePeriodStart`/`ChargePeriodEnd`, `PricingQuantity`, `ConsumedUnit`, and `ContractedCost`. The column names are designed to align with the FinOps Open Cost and Usage Specification (FOCUS) for easier integration with existing FinOps tools. Currently, usage and cost data are updated daily, with plans for more real-time updates in the future.

Impact on Automation and FinOps

The introduction of this API addresses the growing need for machine-readable cost data as infrastructure provisioning and management become increasingly automated. It enables organizations to integrate Cloudflare billing information directly into their financial operations workflows, allowing for better cost monitoring and management by programs rather than relying solely on human-readable dashboards.
