    params={"event_category": "corporate"}
)
events = response.json()
```

## Conceptual Guidance

Corporate events follow the M\&A lifecycle:

* **deal\_type** categorizes the transaction structure
* **regulatory\_status** tracks approval process
* **deal\_value\_usd** enables financial threshold filtering

**Key Distinction**: "Friendly Acquisition" vs "Hostile Takeover" - determined by target company board approval.
