Welcome to CL Forge!

Simple yet powerful Chilean tools written in Rust and Python.

cl-forge provides a collection of high-performance utilities for common Chilean data formats and API integrations. The core logic is implemented in Rust for maximum speed, with a clean and easy-to-use Python interface.

Features

• High Performance: Core logic written in Rust.
• Verify: Efficiently validate Chilean RUT/RUN and PPU (License Plates).
• API Integrations: Simple clients to interact with the CMF and Public Market APIs.
• Type Safety: Full type hints and .pyi stubs for excellent IDE support.

Examples

Validate

You can validate if a verifier digit is correct for a given numeric part of a RUT/RUN.

from cl_forge import verify

is_valid = verify.validate_rut(8750720, "3")

print(f"RUT is valid: {is_valid}")
# RUT is valid: True

... Or you can calculate the verifier digit yourself.

from cl_forge import verify

dv = verify.calculate_verifier(8750720)

print(f"Verifier digit: {dv}")
# Verifier digit: 3

Generate

Need to generate a bunch of random, unique and valid RUTs? No problem! And you can even specify a random seed, so you can reproduce the same results every time.

from cl_forge import verify

ruts = verify.generate(
   n=100,
   min=1_000_000,
   max=20_000_000,
   seed=42
)

print(ruts)
# [{'correlative': 8750720, 'verifier': '3'}, ...]

API Clients

The CMF API client allows you to easily interact with the CMF API.

from cl_forge.cmf import CmfClient

client = CmfClient(api_key="your-api-key")

# Get latest IPC data
ipc_data = client.get(path="/ipc")

print(ipc_data)
# {'IPCs': [{'Valor': '-0,2', 'Fecha': '2025-12-01'}]}

Important

To use the CMF API, you need an API key. You can request one at Contact CMF.

See the API Reference for endpoint-specific clients, and the CMF API documentation for details about all the available endpoints.

The Public Market API client also allows you to easily interact with the Mercado Público API.

from cl_forge.market import MarketClient

client = MarketClient(ticket='your-api-ticket')

tenders_data = client.get(path="/licitaciones")

print(tenders_data)
#{'Cantidad': 463,
# 'FechaCreacion': '2026-02-12T16:07:58.813315Z',
# 'Version': 'v1',
# 'Listado': [{'CodigoExterno': '1057049-30-B226',
#   'Nombre': 'CSP- SERVICIO DE INMUNOHISTOQUÍMICA Y CISH',
#   'CodigoEstado': 5,
#   'FechaCierre': '2026-02-23T15:30:00'},
#  {'CodigoExterno': '1057374-8-L126',
# ...}

Important

To use the Mercado Público API, you need an API ticket. You can request one at Contact Mercado Público. To request this API ticket, you will also have to request and activate your ClaveÚnica.

See the Mercado Público API documentation for details about all the available endpoints. Endpoint-specific clients coming soon in future updates.
