Headers

X-OrcaRouter-Include-Coststring
Example:true

Opt in to per-request cost reporting. When true (or 1, case-insensitive), the billed cost of the call is added to the response's usage object — usage.cost_usd on the OpenAI and Anthropic formats, usageMetadata.costUsd on the Gemini format. On streams it rides the frame carrying final usage (send stream_options: {"include_usage": true} on the OpenAI format). Absent or any other value means off. See Per-request cost.
