Hi — I am using Vercel AI SDK in my app, and the OpenRouter provider (https://github.com/OpenRouterTeam/ai-sdk-provider/) to actually access the models. I want to enable OR's usage accounting feature (https://openrouter.ai/docs/use-cases/usage-accounting) to get cost at the end of the stream, but I can't figure out how to do so. I've tried putting an extraBody in the createOpenRouter call:
apiKey: process.env.OPENROUTER_API_KEY,
extraBody: { usage: { include: true } },
})```
as well as passing providerOptions to openrouter in the streamText call:
``` const result = streamText({
model: openrouter.chat('openai/gpt-4o'),
messages: [{ role: 'user', content: 'hello' }],
providerOptions: {
openrouter: { usage: { include: true } },
},
})
but neither of these seem to work. I get back the basic accounting ( { promptTokens: 1786, completionTokens: 6, totalTokens: 1792 },) but not the fuller one with cost etc.
Would welcome any ideas! Thank you.
