coin-api 1.2.7

A simple CoinMarketCap scraper to fetch cryptocurrency data.

Coin API — simple CoinMarketCap scraper

A small, educational Python scraper that fetches basic data (price, 24h change, market cap) for a cryptocurrency from CoinMarketCap.

What it returns

• Price
• 24-hour change
• Market cap

Project files

• coin_api/COIN_API.py — contains the Coin class and a small demo loop when run as a module.
• requirements.txt — minimal dependency list (may need to add beautifulsoup4).

Requirements

• Python 3.8+
• requests
• beautifulsoup4

Install (PowerShell)

pip install -r requirements.txt
pip install beautifulsoup4

Or install both directly:

pip install requests beautifulsoup4

Usage (as a module)

from coin_api.COIN_API import Coin

coin = Coin("bitcoin")          # coinmarketcap slug (e.g. "bitcoin", "ethereum")
data = coin.get_data()           # returns a dict or False on error
print(data)

Run the included demo

python -m coin_api.COIN_API

Example output (subject to site HTML changes):

{
  "Price": "$61,234.56",
  "24h change": "+2.34% ↗️",
  "Market cap": "$1,150,000,000,000"
}

Notes & limitations

• This scraper parses CoinMarketCap's public HTML. If the site changes structure, the parser may break.
• Avoid frequent automated requests; prefer official APIs (CoinMarketCap API, CoinGecko, Coinbase) for production use.
• Error handling in the code is minimal; consider adding timeouts, retries, logging, and clearer exceptions.

Suggested next steps I can implement

• Add a CLI entrypoint that accepts a coin slug and prints JSON.
• Add unit tests with mocked HTTP responses.
• Update requirements.txt to pin dependency versions (e.g. requests==2.31.0, beautifulsoup4==4.12.2).
