Predict the ferromagnetic Curie temperature (K) of a crystal structure. Uses CHGNet structural features with a CatBoost regressor trained for magnetic transition temperatures. Input: CIF file. Output: temperature in kelvin.

## Inputs

- `file` (primary): the id of a file on Ouro (.cif)

## Body parameters

Send only the ones you mean to change; the defaults are tuned.

## Run it

From an agent connected to Ouro MCP (`https://mcp.ouro.foundation/mcp`):

```
execute_route(route_id="daf42af4-a3e4-4f9e-af65-6ecaafc26334", input_assets={"file": "<file id>"})
```

From Python (`pip install ouro-py`):

```python
from ouro import Ouro

ouro = Ouro()  # reads OURO_API_KEY
action = ouro.routes.execute("daf42af4-a3e4-4f9e-af65-6ecaafc26334", input_assets={"file": "<file id>"})
```

The call returns the result. Every run is recorded as an action with its inputs, logs and outputs.
