Arbitrary JSON API powered by GPT-4o

This endpoint generates JSON data based on the URL path and query parameters.

Try some examples:

\n `);\n }\n\n // System prompt to set the context and rules for the AI\n const systemPrompt =\n `You are a powerful API that generates structured JSON data based on a user's request. The request is described by an HTTP path and query parameters. Your only output must be a valid JSON object. Do not include any explanatory text, markdown, or code fences (like \\`\\`\\`json). Just the raw JSON.`;\n\n // User prompt that includes the specific request details\n const userPrompt = `\n Generate a JSON object for the following data request.\n\n Resource Path: ${path}\n Query Parameters: ${JSON.stringify(queryParams)}\n\n Based on the path and parameters, infer the user's intent and create a plausible, well-structured JSON response.\n For example, a request for '/users/123?fields=name,email' should return an object like {\"name\": \"John Doe\", \"email\": \"john.doe@example.com\"}.\n `;\n\n try {\n // Call the OpenAI Chat Completions API\n const completion = await openai.chat.completions.create({\n model: \"gpt-4o\",\n messages: [\n { role: \"system\", content: systemPrompt },\n { role: \"user\", content: userPrompt },\n ],\n // This is crucial for ensuring the output is always valid JSON\n response_format: { type: \"json_object\" },\n });\n\n const jsonString = completion.choices[0].message.content;\n\n // Parse the string response from the AI into a JSON object\n const jsonData = JSON.parse(jsonString);\n\n // Return the JSON object. Hono sets the 'Content-Type' header automatically.\n return c.json(jsonData);\n } catch (error) {\n console.error(\"Error calling OpenAI or parsing JSON:\", error);\n // Return a structured error message if something goes wrong\n return c.json({\n error: \"Failed to generate JSON response.\",\n details: error.message,\n }, 500);\n }\n});\n\n// Export the Hono app's fetch handler, which is the standard for Val Town HTTP endpoints\nexport default app.fetch;","deleted","label","synthesize",[98],"permalink","https://www.val.town/x/talkbot/Synthesize/code/main.tsx","extension","actionData","errors"]
