can be triggered by API calls, cron jobs, etc.\n\n![Screenshot 2025-05-29 at 8.03.54 PM.png](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/8d53ae11-7cc7-415d-9a2d-edd9c66c5500/public)\n\n## Setup\nRemix this Val into your Val Town account.\n\nConfigure the following variables in your environment: \n- `AGENT_API_KEY` (This is a secure token that you choose to secure the agent.tsx POST endpoint)\n- `OPENAI_API_KEY` (An OpenAI API Key)\n- `EXA_API_KEY` (Optional, though needed if you use the web search tool)\n\n## Usage\nUse `demo.tsx` to send objectives to your agent. \n\n### API Usage\nTo use the API from another client, you can POST authenticated requests to the agent.tsx endpoint:\n\n```javascript\nconst requestBody = {\n messages: [\n { role: \"user\", content: \"What is the difference in height between the Salesforce Tower and the Empire State Building?\" },\n ],\n streamResults: false,\n};\n\nconst response = await fetch(\"https://.web.val.run/\", {\n method: \"POST\",\n headers: {\n \"Content-Type\": \"application/json\",\n \"Authorization\": `Bearer ${Deno.env.get(\"AGENT_API_KEY\")}`,\n },\n body: JSON.stringify(requestBody),\n});\n```\n\n### Streaming Chat\nThe API will also work with streaming chat front ends based on the Vercel AI SDK's useChat hook.\n\nYou just need to pass `streamResults: true` in your API POST request.\n\n## Using Other Models\nIt is easy to reconfigure the agent to work with other providers that are supported by Vercel's AI SDK, though not all models support tool calling. \n\nAnthropic's models should work well, but the system prompt would need to be retuned to work with Claude.\n\nLearn more:
