v0

v0 is a skill for Claude Code from Elnora-AI/elnora-ai-agent-hackathon-starter-kit. It costs 46 tokens per session (1,214 once invoked), scanned A, original, Apache-2.0.

A skill for using Vercel v0, an AI service that generates user interfaces, components, and applications from code. It works through v0’s Platform API or its model API.

In plain words
What is it for?
Use it to generate or refine frontend code and full apps, call v0 models from another application, and work with v0 API keys and credits.
Why use it?
It lets an agent create and iterate on v0 projects programmatically instead of using only the v0 website.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

v0 scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Vercel v0

v0 is Vercel's AI app builder. Beyond the web UI at v0.app, it exposes a Platform API (and an OpenAI-compatible model API) so you can generate UIs, components, and full apps from code.

Hackathon note: participants receive v0 credits. The API bills against those credits, so you can drive v0 from the CLI without a paid upgrade as long as credits remain. Check usage at v0.app/settings/billing.

There are two distinct surfaces — pick the right one:

Surface Package / endpoint Use it for
Platform API v0-sdk (npm), https://api.v0.dev/v1 Create/iterate chats that return generated files, demos, and deployable projects. This is the real "v0 builds my app" surface.
Model API AI SDK @ai-sdk/vercel, https://api.v0.dev/v1 (OpenAI-compatible) Use v0's models (v0-1.5-md, etc.) as a chat/completions model inside your own app.

Setup (do this first)

  1. Get an API keyv0.app/settings/keys. The key grants full access to the v0 account — treat it as a secret.
  2. Store it as an env var, never in code or flags. Add to .env (gitignored):
    echo 'V0_API_KEY=your-v0-api-key' >> .env
    
    The SDK and CLI read V0_API_KEY automatically.
  3. Verify access:
    curl -s https://api.v0.dev/v1/user \
      -H "Authorization: Bearer $V0_API_KEY" | head
    
    A JSON user object means the key works. 401 means the key is wrong or credits/billing aren't enabled on the account.

Fastest path: scaffold a v0-powered app

# Spins up a Next.js app pre-wired to the v0 Platform API
pnpm create v0-sdk-app@latest my-v0-app
# or: npx create-v0-sdk-app@latest my-v0-app

Platform API via the SDK (generate UI from a prompt)

pnpm add v0-sdk        # or: npm install v0-sdk
import { v0 } from 'v0-sdk' // reads V0_API_KEY from the environment

// Create a chat — v0 generates the app and returns a live demo + files
const chat = await v0.chats.create({
  message: 'Build a landing page for a biotech hackathon with a hero and signup form',
})

console.log('Preview:', chat.demo)        // hosted preview URL
console.log('Chat:', chat.url)            // open/iterate in the v0 web UI
// chat.files[] holds the generated source files

// Iterate on the same chat
const next = await v0.chats.sendMessage({
  chatId: chat.id,
  message: 'Make the hero dark mode and add a pricing section',
})

v0 is a skill published in the GitHub repository Elnora-AI/elnora-ai-agent-hackathon-starter-kit (22 stars, last pushed yesterday), licensed Apache-2.0. It adds 46 tokens to every session and 1,214 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
