Quickstart

To perform anomaly detection, use the detect_anomalies method. Then, plot the anomalies using the plot method.

import pandas as pd
from nixtla import NixtlaClient

nixtla_client = NixtlaClient(
    # defaults to os.environ.get("NIXTLA_API_KEY")
    api_key = 'my_api_key_provided_by_nixtla'
)

Use an Azure AI endpoint

To use an Azure AI endpoint, set the base_url argument:

nixtla_client = NixtlaClient(base_url="you azure ai endpoint", api_key="your api_key")

# Read the dataset
df = pd.read_csv('https://datasets-nixtla.s3.amazonaws.com/peyton-manning.csv')

# Detect anomalies
anomalies_df = nixtla_client.detect_anomalies(df, freq='D')

# Plot anomalies
nixtla_client.plot(df, anomalies_df)

Available models in Azure AI

If you use an Azure AI endpoint, set model="azureai"

nixtla_client.detect_anomalies(..., model="azureai")

For the public API, two models are supported: timegpt-1 and timegpt-1-long-horizon.

By default, timegpt-1 is used. See this tutorial for details on using timegpt-1-long-horizon.
