Dart quickstart

A short "hello world" that authenticates with the Cryptohopper API and prints your account info plus the BTC/USDT price.

Run it

export CRYPTOHOPPER_TOKEN=your-40-char-bearer
dart pub get
dart run

What it shows

• How to construct CryptohopperClient with a bearer token (and close() it via try/finally)
• One authenticated call: await ch.user.get()
• One market-data call: await ch.exchange.ticker(exchange: ..., market: ...)
• Typed error handling via on CryptohopperException catch (e)

Where to get a token

cryptohopper.com developer dashboard → Create OAuth app → drive the consent flow once. See oauth/ for runnable OAuth examples, or use the cryptohopper CLI (cryptohopper login) which handles the flow for you.

Dependencies

Just one — cryptohopper (resolved via git: ref while the package isn't on pub.dev yet — see the Dart SDK README for status). Requires Dart 3.2+.
