# Quickstart

> Get a test API key and make your first request in under a minute

## 1. Get a test API key

Test keys are free and valid for 10 minutes. No signup required.

```bash theme={"theme":"one-dark-pro"}
curl -X POST https://api.delphiterminal.co/api/v1/test-key
```

You'll get back a response like:

```json theme={"theme":"one-dark-pro"}
{
  "api_key": "dphi_live_a1b2c3d4...",
  "expires_at": "2025-01-01T00:10:00Z",
  "expires_in": "10 minutes"
}
```

Copy the `api_key` value — you'll use it in the next step.

## 2. Make your first request

Use your API key in the `X-API-Key` header to fetch a Kalshi market:

```bash theme={"theme":"one-dark-pro"}
curl -X GET 'https://api.delphiterminal.co/api/v1/klsi/markets' \
  -H 'X-API-Key: dphi_live_a1b2c3d4...'
```

Or search across all markets:

```bash theme={"theme":"one-dark-pro"}
curl -X GET 'https://api.delphiterminal.co/api/v1/events/search?q=bitcoin' \
  -H 'X-API-Key: dphi_live_a1b2c3d4...'
```

## 3. Explore the API

Use the **API Reference** tab to browse all available endpoints. Every endpoint has a built-in playground where you can test requests directly in your browser.
