v0 API

The v0-1.0-md model is designed for building modern web applications. It supports text and image inputs, provides fast streaming responses, and is compatible with the OpenAI Chat Completions API format.

• Framework aware completions: Evaluated on modern stacks like Next.js and Vercel.
• Auto-fix: Identifies and corrects common coding issues during generation.
• Quick edit: Streams inline edits as they’re available.
• OpenAI compatible: Can be used with any tool or SDK that supports OpenAI's API format.
• Multimodal: Supports both text and image inputs (base64-encoded image data).

You can experiment with the v0-1.0-md model in the AI Playground to test prompts and view responses.

The v0 API is currently in beta and requires a Premium or Team plan with usage-based billing enabled. For details, visit the pricing page.

To start using the v0-1.0-md model, create an API key on v0.dev.

You can then integrate it using the AI SDK, a TypeScript library designed for working with v0 and other OpenAI-compatible models.

npm install ai @ai-sdk/vercel

import { generateText } from 'ai';
import { vercel } from '@ai-sdk/vercel';
 
const { text } = await generateText({
  model: vercel('v0-1.0-md'),
  prompt: 'Create a Next.js AI chatbot with authentication',
});

The v0-1.0-md model is the default model served by the v0 API.

Capabilities:

• Supports text and image inputs (multimodal)
• Compatible with OpenAI’s Chat Completions format
• Supports function/tool calls
• Streaming responses with low latency
• Optimized for frontend and full-stack web development

This endpoint generates a model response based on a list of messages.

Each message object must contain:

curl https://api.v0.dev/v1/chat/completions \
  -H "Authorization: Bearer $V0_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "v0-1.0-md",
    "messages": [
      { "role": "user", "content": "Create a Next.js AI chatbot" }
    ]
  }'

curl https://api.v0.dev/v1/chat/completions \
  -H "Authorization: Bearer $V0_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "v0-1.0-md",
    "stream": true,
    "messages": [
      { "role": "user", "content": "Add login to my Next.js app" }
    ]
  }'

If stream is false (default), the response is a JSON object:

{
  "id": "v0-123",
  "model": "v0-1.0-md",
  "object": "chat.completion",
  "created": 1715620000,
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "Here's how to add login to your Next.js app..."
      },
      "finish_reason": "stop"
    }
  ]
}

If stream is true, the server returns a series of data chunks formatted as Server-Sent Events (SSE). Each line begins with data: followed by a partial delta:

{
  "id": "v0-123",
  "model": "v0-1.0-md",
  "object": "chat.completion.chunk",
  "choices": [
    {
      "delta": {
        "role": "assistant",
        "content": "Here's how"
      },
      "index": 0,
      "finish_reason": null
    }
  ]
}
