description: 'Four Australian data APIs on one key — subscriptions, trade pricing, PBS drugs, and rental prices.
---
## Quick start
**1. Get your API key** — register in one request:
```
POST /v1/auth/register
{"email": "you@example.com", "name": "Your Name"}
```
Copy the `api_key` from the response.
**2. Authenticate** — add your key to every request as a header:
```
X-API-Key: ar_live_xxxxxxxxxxxx
```
**3. Run the discovery endpoint** — returns all available slugs, example calls, and your account limits:
```
GET /v1/discovery
```
**4. Make your first call:**
```
GET /v1/prices/netflix?country=AU
GET /v1/trades/electrician/prices?state=NSW&country=AU
GET /v1/pbs/metformin
GET /v1/rental/VIC/Richmond
```
