Code Review
This pull request introduces a comprehensive "Official Provider" and credit system, including a backend proxy, user credits, and Stripe integration for top-ups. The UI has been updated to reflect these changes. The implementation is solid, but I've identified a critical race condition in the credit handling logic on the server that could lead to incorrect credit balances. I've also suggested some minor typing improvements for better code quality and maintainability.

This method has a race condition. If multiple requests to consume credits arrive concurrently, they might all read the same credit balance before any of them can update it. This could lead to the user's balance going negative.
To fix this, you should perform the credit check and deduction in a single atomic database operation. You can achieve this by using a WHERE clause to check for sufficient credits during the UPDATE statement. You'll need to import sql, and, and gte from drizzle-orm.
import { eq, and, gte, sql } from 'drizzle-orm' async consumeCredits(userId: string, amount: number) {
// This ensures the user has a credit record, creating one if it doesn't exist.
await this.getCredits(userId)
const result = await db.update(schema.userCredits).set({
credits: sql`${schema.userCredits.credits} - ${amount}`,
updatedAt: new Date(),
}).where(and(
eq(schema.userCredits.userId, userId),
gte(schema.userCredits.credits, amount)
)).returning()
if (result.length === 0) {
throw new Error('Insufficient credits')
}
return result[0]

This method has a race condition. If multiple requests to add credits arrive concurrently, they might both read the same credit balance before updating it, leading to lost credit updates.
To fix this, you should perform the credit addition as a single atomic database operation. You can use Drizzle's sql helper for this. You'll need to import sql from drizzle-orm.
import { eq, sql } from 'drizzle-orm' async addCredits(userId: string, amount: number) {
// This ensures the user has a credit record, creating one if it doesn't exist.
await this.getCredits(userId)
const [updated] = await db
.update(schema.userCredits)
.set({
credits: sql`${schema.userCredits.credits} + ${amount}`,
updatedAt: new Date(),
})
.where(eq(schema.userCredits.userId, userId))
.returning()
return updated

The env parameter is typed as any. For better type safety, it should be typed with the Env type from ../services/env. You'll need to import it:
import type { Env } from '../services/env'| export function createV1Routes(creditsService: CreditsService, env: any) { | |
| export function createV1Routes(creditsService: CreditsService, env: Env) { |
|

The context object c is typed as any. It should be properly typed as Context<HonoEnv> for type safety and autocompletion. You'll need to import Context from hono.
import type { Context } from 'hono'| async function handleCompletion(c: any) { | |
| async function handleCompletion(c: Context<HonoEnv>) { |
