bcch-sdk 0.7.0

Python SDK for the Banco Central de Chile SieteRestWS API.

Banco Central Chile SDK

A Python client library for the Banco Central de Chile SieteRestWS API.

This repository provides sync and async wrappers over the API, returning data as pandas.DataFrame or polars.DataFrame and managing retries, timeout configuration, and error handling.

Features

• Synchronous and asynchronous SDK layers
• Built-in HTTP retries using httpx-retries
• Configurable httpx.Timeout
• get_series(...) and search_series(...)
• Output as pandas.DataFrame or polars.DataFrame
• Standard logging integration using logging.getLogger(__name__)
• Typed configuration and credentials

Requirements

• Python 3.12+
• httpx[brotli,zstd]
• pydantic
• polars
• pandas
• httpx-retries

pandas and polars are runtime dependencies by design for the 0.x and 1.0 release line because DataFrame responses are part of the core SDK contract. They may be split into optional extras in a future release after the stable API is established.

Installation

This project uses a src/ layout and exposes the bcch_sdk package.

Use Poetry if available:

poetry install

Or install the runtime dependencies manually:

python -m pip install httpx[brotli,zstd] pydantic polars pandas httpx-retries

If you want to run code from the repository directly, make sure the src/ folder is on PYTHONPATH:

export PYTHONPATH=$(pwd)/src

Quickstart

Import the SDK classes and configure the client using BCChConfig.

Sync example

from httpx import Timeout
from bcch_sdk import BCChSyncSDK
from bcch_sdk.types import BCChConfig

config = BCChConfig(
    credentials={"username": "your_user", "password": "your_pass"},
    timeout=Timeout(10.0),
)

sdk = BCChSyncSDK(configuration=config)

series_data = sdk.get_series(
    time_series="SF6041",
    first_date="2023-01-01",
    last_date="2023-12-31",
    polars_response=False,
)

print(series_data)

Async example

import asyncio
from httpx import Timeout
from bcch_sdk import BCChAsyncSDK
from bcch_sdk.types import BCChConfig

async def main() -> None:
    config = BCChConfig(
        credentials={"username": "your_user", "password": "your_pass"},
        timeout=Timeout(10.0),
    )

    sdk = BCChAsyncSDK(configuration=config)

    series_data = await sdk.get_series(
        time_series=["SF6041", "SF6060"],
        first_date="2023-01-01",
        last_date="2023-12-31",
        polars_response=True,
    )

    print(series_data)

asyncio.run(main())

Search series example

from bcch_sdk.types import Frequency

result = sdk.search_series(Frequency.MONTHLY, polars_response=False)
print(result)

Configuration

The main configuration object is BCChConfig from bcch_sdk.types.config.

• credentials: a typed dict with username and password
• timeout: an httpx.Timeout object

The SDK clients use httpx under the hood and will apply retries and timeout settings automatically.

Logging

This library uses logging.getLogger(__name__) in each module. Consumers should configure handlers and levels in their own applications.

Example:

import logging

logging.basicConfig(level=logging.INFO)
