API Data Fetcher

Purpose

This skill helps economists fetch data from major economic data APIs including FRED (Federal Reserve Economic Data), World Bank, IMF, BLS, and OECD. It generates clean, documented Python code with proper error handling.

When to Use

Downloading macroeconomic indicators
Building custom datasets from multiple sources
Automating data updates for ongoing projects
Fetching cross-country panel data

Instructions

Step 1: Identify Data Requirements

Ask the user:

What data do you need? (GDP, unemployment, inflation, etc.)
What time period and frequency?
What countries/regions?
Preferred output format? (CSV, DataFrame, etc.)

Step 2: Select Appropriate API

Data Type	Best Source	Package
US macro	FRED	`fredapi`
Global development	World Bank	`wbdata`
Labor statistics	BLS	`bls`
Cross-country	OECD	`pandasdmx`
Financial	Yahoo Finance	`yfinance`

Step 3: Generate Clean Code

Include:

API key handling (environment variables)
Error handling for API failures
Data cleaning and formatting
Documentation of series definitions
