# Claimable Postgres

Instant Postgres databases for local development, demos, prototyping, and test environments. No account required. Databases expire after 72 hours unless claimed to a Neon account.

## Quick Start

```bash
curl -s -X POST "https://neon.new/api/v1/database" \
  -H "Content-Type: application/json" \
  -d '{"ref": "agent-skills"}'
```

Parse `connection_string` and `claim_url` from the JSON response. Write `connection_string` to the project's `.env` as `DATABASE_URL`.

For other methods (CLI, SDK, Vite plugin), see [Which Method?](#which-method) below.

## Which Method?

- **REST API**: Returns structured JSON. No runtime dependency beyond `curl`. Preferred when the agent needs predictable output and error handling.
- **CLI** (`npx neon-new@latest --yes`): Provisions and writes `.env` in one command. Convenient when Node.js is available and the user wants a simple setup.
- **SDK** (`neon-new/sdk`): Scripts or programmatic provisioning in Node.js.
- **Vite plugin** (`vite-plugin-neon-new`): Auto-provisions on `vite dev` if `DATABASE_URL` is missing. Use when the user has a Vite project.
