希望/api/actions/users/getUsers返回lastProviderCostMultiplier

[WAY29]

现在接口已经返回了lastProviderName,希望能返回lastProviderCostMultiplier，即最后使用的供应商的成本倍数，主要用来编写我自己的cch-statusline

Thank you for this feature suggestion.

Feasibility assessment:
This is a reasonable enhancement request. The costMultiplier field already exists in the providers table and is available in the database schema.

Current implementation:
The /api/actions/users/getUsers endpoint returns lastProviderName for each key through the KeyStatistics interface. The data flow is:

1. src/actions/users.ts (lines 168-311) - The getUsers() function calls findKeysWithStatisticsBatch()
2. src/repository/key.ts (lines 538-548) - The KeyStatistics interface defines the returned statistics:

   export interface KeyStatistics {
     keyId: number;
     todayCallCount: number;
     lastUsedAt: Date | null;
     lastProviderName: string | null;
     modelStats: Array<{...}>;
   }

3. src/repository/key.ts (lines 706-721) - The query that retrieves lastProviderName already joins with the providers table:

   const lastUsageRows = await db
     .selectDistinctOn([messageRequest.key], {
       key: messageRequest.key,
       createdAt: messageRequest.createdAt,
       providerName: providers.name,
     })
     .from(messageRequest)
     .innerJoin(providers, eq(messageRequest.providerId, providers.id))
     ...

Implementation considerations:

• The costMultiplier field is defined in src/drizzle/schema.ts (line 142) as numeric('cost_multiplier', { precision: 10, scale: 4 })
• Since the query already joins with the providers table, adding costMultiplier to the select would be straightforward
• Changes would be needed in:
  • src/repository/key.ts: Add costMultiplier to KeyStatistics interface and the query
  • src/types/user.ts: Add lastProviderCostMultiplier to UserKeyDisplay interface
  • src/actions/users.ts: Pass through the new field in the response mapping

This appears to be a low-complexity enhancement that aligns well with the existing architecture.
