# Welcome (/docs/introduction/welcome)



[Trendtracker](https://trendtracker.ai) helps teams spot meaningful shifts in technology and markets earlier.\
The [Connect API](https://connect-api.trendtracker.ai/docs) gives you direct programmatic access to that intelligence.

## Getting Started [#getting-started]

1. Ask the [Trendtracker team](mailto:mathias.colpaert@trendtracker.ai) for an API key.
2. Store your key in an environment variable.
3. Make your first request to discover a topic.
4. Use topic ids to fetch indicators and time series.

```json
{
  "query": "precision fermentation",
  "take": 5
}
```

```bash
export TT_API_KEY="your-api-key"
curl -s "https://connect-api.trendtracker.ai/topics?query=precision%20fermentation&take=5" \
  -H "x-api-key: $TT_API_KEY"
```
