Developers and founders frequently lose hours configuring heavy financial libraries like `yfinance` or wrestling with API key management just to extract basic ticker data.

This zero-config solution eliminates the bloat by condensing powerful fetching capabilities into a single, self-contained Python file. You can execute complex data queries immediately after download, bypassing the need for multi-file setups or Python environment dependencies.

What's included:

  • Zero-Configuration Execution -- Eliminates setup time by running immediately without API keys, authentication tokens, or environment variables.
  • Single-File Portability -- Allows you to move the free-micro-chart.py tool anywhere in your project structure or run it from a USB drive without breaking dependencies.
  • Flexible Historical Range -- Retrieves exactly the timeframe you need using the --days N flag (default 30), allowing for quick trend analysis or long-term auditing.
  • Granular Interval Control -- Provides precise data resolution via --interval flags, supporting 1d, 5d, or 1mo to match your reporting granularity.
  • Universal Ticker Support -- Fetches data instantly for any standard ticker symbol (e.g., AAPL) without writing boilerplate code or handling rate limits.

Who this is for:

This tool is engineered for developers, solo founders, and growth or SEO teams who need immediate market context integrated into their workflows. It is specifically designed for technical users who value speed and modularity and are frustrated by the friction of installing heavy libraries for simple data extraction tasks.

Real example:

Before: A growth hacker spent 45 minutes reading documentation and installing dependencies just to pull 30 days of closing prices for a quick blog post visualization. After: They downloaded the script and ran `python free-micro-chart.py AAPL --days 30`, receiving the data instantly without writing a single line of code.

What you'll achieve:

  • Reduce data acquisition time from hours of configuration to seconds of execution.
  • Eliminate variable overhead by utilizing a standalone file rather than complex package managers.
  • Integrate real-time financial checks into existing automation scripts with zero friction.

FAQ:

Technical requirements? Python 3.10+ or as specified in README. No coding experience needed to run.
