Interface: UsageCostBreakdown#

Defined in: packages/ai/src/types.ts:935

Provider-reported cost breakdown for a single request, normalized onto a canonical shape so consumer code is portable across gateways. Each adapter's extractor maps its provider-specific wire keys (e.g. OpenRouter's upstream_inference_prompt_cost, upstream_inference_input_cost) onto these fields at runtime.
