What if CMC fucks up big time, and displays the wrong price? This
has happened before, and if you don't detect this, some seller is going to be very disappointed while your buyer hits the jackpot!
We anticipated that situations like this could happen if the CoinMarketCap API fails to work properly.
That's why we integrated two backup price providers: CoinGecko API and Coinlib API.
The system works as follows:If CMC API goes down, then backup CoinGecko API is activated.
If CoinGecko API also fails -> the second backup Coinlib API takes over.
The probability of all three APIs failing at the same time is extremely low.
Of course, I understand your concern, but nothing in crypto is 100% safe. But risks can be minimized through cautious preparation and layered backups, which is exactly what we've built in.
What if CMC's API still works, but gives the wrong prices (as in: 1 BTC is worth $799 billion): do you also compare those to other APIs instead of just switching to a backup API?
