Edited at 2024-04-06 15:17 UTC. With Bybit API v5 [1] it is possible to get public data (price, volume, last trading records) and also place own orders using API Key. All the next examples do not need API Key, because open public data is used here.
First, install jq for read json data and search in it to get only fields we need.
apt install jq

curl cannot verify certificates on Android
Also, I had a problem getting data via HTTPS on Android with curl:
curl 'https://api-testnet.bybit.com/public/linear/recent-trading-records?symbol=BTCUSDT&limit=1'
curl: (77) error setting certificate verify locations:
CAfile: /etc/ssl/certs/ca-certificates.crt
CApath: /etc/ssl/certs
First, I used option -k for curl does not check certificates. But then I fixed this with [2], need to install ca-certificates:
apt install ca-certificates
