For bots, historical data matters more than people think. That’s where most APIs fall short — CMC is actually decent there

I’ve been experimenting with a small crypto trading bot and one thing I underestimated was how important good data is.

Initially tried scraping + a couple free APIs… didn’t go well.

Switched to CoinMarketCap API and it’s been way more reliable so far.

Main things I’m using:

real-time price quotes

historical data for strategy testing

exchange + market pair data

Data updates are pretty frequent (around every minute), which is decent for most strategies.

Also nice that it aggregates data from a ton of exchanges, so you’re not relying on a single source.

Still figuring out:

best way to structure backtesting

whether to combine it with another API for redundancy

What are you guys using for trading bots? Single API or multiple?
