Use openrouter stream_options include_usage

[mrubens]

Context

Per OpenRouter: "Now you can send us stream_options: {include_usage: true} to get the usage directly in the completion request."

Implementation

This replaces the previous polling and grabs the usage information directly.

---

Important

Update OpenRouter integration to use stream_options: { include_usage: true } for direct usage data retrieval, removing polling.

• Behavior:
  • Replaces polling with stream_options: { include_usage: true } in createMessage() in openrouter.ts to directly obtain usage data.
  • Removes axios-based polling for usage data in openrouter.ts and openrouter.test.ts.
• Functions:
  • Adds processUsageMetrics() in openrouter.ts to handle usage data processing.
• Tests:
  • Updates createMessage test in openrouter.test.ts to verify usage data is included in stream response.

Consider replacing the any type in processUsageMetrics with a properly defined interface for the usage object. This helps ensure type safety and clarity for the expected structure.
