I already have a small Python bot that pulls cryptocurrency prices, trading volumes, and general market-trend data from the CoinGecko API and dumps everything into a simple .txt file for later upload to my blog. The core logic works, but it regularly trips the API’s limits (HTTP 429) and sometimes throws random connection or JSON errors that stop the whole run.
What I need now is a clean, reliable upgrade: • add proper rate-limiting that respects CoinGecko’s published threshold (a lightweight decorator or helper class is fine, as long as it’s clear and adjustable); • build solid retry logic with exponential back-off so transient issues don’t kill the job; • wrap all calls in sensible error handling, logging any failure without losing the day’s data; • keep the output format identical—a plain .txt file I can copy-paste to the blog.
