Data Bridges Knots

This Python module allows you to get data from the WFP Data Bridges API, including household survey data, market prices, exchange rates, GORP (Global Operational Response Plan) data, and food security data (IPC equivalent). It is a wrapper for the Data Bridges API Client, providing an easier way to data analysts to get VAM and monitoring data using their language of choice (Python, R and STATA).

Installation

Using uv

👉 We recommend using uv as package manager. You can install it using the instructions here.

Install the data_bridges_knots package in your environment using uv:

uv venv .venv && source .venv/bin/activate && uv pip install git+https://github.com/WFP-VAM/DataBridgesKnots.git

Using pip

You can also install the data_bridges_knots package using regular pip and the Git repository URL:

pip3 install --force-reinstall git+https://github.com/WFP-VAM/DataBridgesKnots.git

STATA and R users will also need the appropriate optional dependencies to use this package in their respective software. To install the package with these dependencies, use the following command:

STATA users

STATA users need to install the data_bridges_knots with additional STATA dependencies (pystata, and stata-setup):

uv venv .venv && source .venv/bin/activate && uv pip install git+https://github.com/WFP-VAM/DataBridgesKnots.git#egg=data_bridges_knots[STATA]

R users

R users need to have reticulate installed in their machine to run this package as explained in the R example file

install.packages("reticulate")
library(reticulate)

Configuration

There are three ways to configure DataBridgesShapes:

Option 1: YAML Configuration File (Recommended for Production)

1. Create a data_bridges_api_config.yaml in the main folder you're running your code from.

2. The structure of the file is:

   NAME: ''
   VERSION : ''
   KEY: ''
   SECRET: ''
   DATABRIDGES_API_KEY: ''
   SCOPES:
   - ''
   - ''

3. Replace the placeholders with your actual API key and secret from the Data Bridges API. Update the SCOPES list with the required scopes for your use case.

Option 2: Dictionary Configuration (Recommended for Testing/Programmatic Use)

You can also initialize the client directly with a Python dictionary:

from data_bridges_knots import DataBridgesShapes

config = {
    'KEY': 'your-api-key',
    'SECRET': 'your-api-secret',
    'VERSION': '5.0.0',
    'SCOPES': [
        'vamdatabridges_household-fulldata_get',
        'vamdatabridges_marketprices-pricemonthly_get'
    ],
    'DATABRIDGES_API_KEY': 'optional-databridges-key'
}

client = DataBridgesShapes(config)

Option 3: Environment Variables (Recommended for CI/CD and Containers)

Set the following environment variables and use the config_from_env() helper:

export DATABRIDGES_KEY="your-api-key"
export DATABRIDGES_SECRET="your-api-secret"
export DATABRIDGES_VERSION="5.0.0"
export DATABRIDGES_SCOPES="scope1,scope2,scope3"
export DATABRIDGES_API_KEY="optional-databridges-key"

Then in your Python code:

from data_bridges_knots.client import config_from_env, DataBridgesShapes

config = config_from_env()
client = DataBridgesShapes(config)

Getting Credentials

• (For WFP users) Credentials and scopes for DataBridges API can be requested by opening a ticket with the TEC Digital Core team. See documentation
• External users can reach out to [email protected] for support on getting the API credentials.

Usage

Full user documentation can be found here

Python

Run the following example to extract commodity data:

from data_bridges_knots import DataBridgesShapes

CONFIG_PATH = r"data_bridges_api_config.yaml"

client = DataBridgesShapes(CONFIG_PATH)

# COMMODITY DATA
commodity_units_list = client.get_commodity_units_list(country_code="TZA", commodity_unit_name="Kg", page=1, format='json')

Additional examples are in the examples folder and in the API Reference document

R

library(reticulate)

# Import the Python module through reticulate
data_bridges_knots <- import("data_bridges_knots")

# Point to our virtual environment's Python
use_python(".venv/bin/python")

# Create client instance
config_path <- "data_bridges_api_config.yaml"
client <- data_bridges_knots$DataBridgesShapes(config_path)

# COMMODITY DATA
# Get commodity unit list for Tanzania
commodity_units <- client$get_commodity_units_list(
  country_iso3 = "TZA",
  commodity_unit_name = "Kg",
  page = 1L,
  format = "json"
)

Additional examples are in the examples folder.

Developer set-up

Installing required tools

This project uses uv to manage dependencies and environments. See here for installation, and here for basic use. uv uses information on dependencies in the pyproject.toml file and continuously maintains a detailed description of the required environment in the uv.lock file.

This project uses make to automate common project management tasks. For installation see: Windows, Ubuntu Linux, OSX

Virtual environment

To set up the environment for the first time (including all dev tools like black, isort, ruff, mypy, pytest, mkdocs, etc.), run:

$ make install

This will install the package with all dependencies and dev tools defined in pyproject.toml.

To run any script or command inside the environment, run:

$ uv run my_script.py

See here for further information on using uv.

Code formatting and linting

Run checks

$ make check-codestyle

Apply fixes

$ make codestyle

Commits

This project uses Commitizen for conventional commits. To create a properly formatted commit:

$ uv run cz commit

This interactive tool guides you through creating commits that follow the Conventional Commits specification.
