API Usage

All examples use ApiClient from a runtime directory supplied by environment configuration. Set SIMILARWEB_RUNTIME_PATH or UNIVERSAL_AI_SANDBOX_RUNTIME to the directory that contains data_api.py.

import os
import sys

runtime_path = (
    os.environ.get("SIMILARWEB_RUNTIME_PATH")
    or os.environ.get("UNIVERSAL_AI_SANDBOX_RUNTIME")
)
if not runtime_path:
    raise RuntimeError("Set SIMILARWEB_RUNTIME_PATH to the directory containing data_api.py")

sys.path.append(runtime_path)
from data_api import ApiClient

Common parameters:

Important: Save Data to Files

API calls may fail mid-execution due to credit depletion. Always save all retrieved data to files immediately to avoid data loss and prevent redundant API calls.
