Learn how to fetch data using the WaveAssist SDK.

​
Basic Usage

import waveassist

# Fetch a string
message = waveassist.fetch_data("welcome_message")
print(message)  # "Hello, World!"

# Fetch a dictionary
user_data = waveassist.fetch_data("user_profile")
print(user_data["name"])  # "Alice"

​
Fetching DataFrames

Error Handling

except waveassist.KeyNotFoundError:
    print("Data not found")
except waveassist.FetchError as e:
    print(f"Failed to fetch data: {e}")

​
Type Handling

The SDK automatically handles type conversion: 
# Original data types are preserved
string_data = waveassist.fetch_data("text_key")  # returns str
dict_data = waveassist.fetch_data("dict_key")  # returns dict
df_data = waveassist.fetch_data("dataframe_key")  # returns pd.DataFrame
