+ ); +} +``` + +#### 3.

Create Worker Backend (Hono) + +**File**: `backend/src/index.ts` + +```typescript +import { Hono } from "hono"; +import { cors } from "hono/cors"; + +const app = new Hono(); + +app.use("/*", cors()); + +app.post("/api/chat", async (c) => { + const { prompt } = await c.req.json(); + + // Use Cloudflare Workers AI or proxy to OpenAI + const response = await fetch("https://api.thesys.dev/v1/embed/chat/completions", { + method: "POST", + headers: { + "Authorization": `Bearer ${c.env.THESYS_API_KEY}`, + "Content-Type": "application/json", + }, + body: JSON.stringify({ + model: "c1/openai/gpt-5/v-20250930", + messages: [ + { role: "system", content: "You are a helpful assistant." }, + { role: "user", content: prompt }, + ], + stream: false, // or handle streaming + }), + }); + + const data = await response.json(); + return c.json(data); +}); + +export default app; +``` + +#### 2.

Rate Limiting Issues + +**Problem**: API calls fail with 429 errors, no retry mechanism. + +**Cause**: No backoff logic for rate limits. + +**Solution**: +```typescript +async function callApiWithRetry(apiCall, maxRetries = 3) { + for (let i = 0; i < maxRetries; i++) { + try { + return await apiCall(); + } catch (error) { + if (error.status === 429 && i < maxRetries - 1) { + const waitTime = Math.pow(2, i) * 1000; // Exponential backoff + await new Promise((resolve) => setTimeout(resolve, waitTime)); + continue; + } + throw error; + } + } +} + +// Usage +const response = await callApiWithRetry(() => + client.chat.completions.create({...}) +); +``` + +--- + +### 12.
