Access billing usage and cost data via API

Vercel now provides programmatic access to billing usage and cost data via API, CLI, and SDK.

• •The new /billing/charges endpoint returns data in the FOCUS v1.3 open-standard format, enabling direct ingestion into FinOps tools without custom transformation.
• •The endpoint supports 1-day granularity with a maximum date range of one year, and responses are streamed as newline-delimited JSON (JSONL) for large datasets.
• •SDK support is available via @vercel/sdk, allowing async iteration over billing charge events with team and date range filters.
• •The vercel usage CLI command displays billing usage for the current period or a custom date range, including credit use and costs per service.
• •Vantage has released a native integration that automatically syncs Vercel usage and cost data alongside other tools for unified cost observability.
