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.
How to run this route from Python with the Ouro SDK.
API access requires an API key. Create one in Settings โ API Keys, then set OURO_API_KEY in your environment. Install the SDK with pip install ouro-py.
POST /magnetism/curie-temperatureParameters and request body schema for this route.
This route accepts no parameters or request body.
Pass the ID of an Ouro asset for each of these in input_assets. Ouro loads the asset and sends it to the route.
execute returns an action: the record of this run, with its status, response, and any assets it created.
import os
from ouro import Ouro
ouro = Ouro(api_key=os.environ.get("OURO_API_KEY"))
# The ID also works, and stays the same if the route is renamed: "daf42af4-a3e4-4f9e-af65-6ecaafc26334"
route = ouro.routes.retrieve("hermes/predict-curie-temperature-from-a-cif")
action = route.execute(
input_assets={
"file": "your-file-id",
},
)
print(action.status) # "success" or "error"
print(action.final_data)To avoid blocking on a slow run, start it without waiting and collect the result later.
# Returns as soon as the run is accepted
action = route.execute(
input_assets={
"file": "your-file-id",
},
wait=False,
)
print(action.id, action.status)
# Later, even from another process
action = ouro.routes.poll_action(str(action.id), poll_interval=5, timeout=1800)
print(action.final_data)By default a failed run comes back as an action with status error. Pass raise_on_error=True to raise an exception instead.
