10- `AGENT_API_KEY` (This is a secure token that you choose to secure the agent.tsx POST endpoint)
11- `OPENAI_API_KEY` (An OpenAI API Key)
12- `EXA_API_KEY` (Optional, though needed if you use the web search tool)

18To use the API from another client, you can POST authenticated requests to the agent.tsx endpoint:
19
20```javascript
30  headers: {
31    "Content-Type": "application/json",
32    "Authorization": `Bearer ${Deno.env.get("AGENT_API_KEY")}`,
33  },
34  body: JSON.stringify(requestBody),

38### Streaming Chat
39The API will also work with streaming chat front ends based on the Vercel AI SDK's useChat hook.
