kotlin

Kotlin 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
./gradlew run

Maven Central pending. Until the Kotlin SDK is published, the mavenLocal() line in build.gradle.kts resolves it from a local install:

git clone https://github.com/cryptohopper/cryptohopper-kotlin-sdk
cd cryptohopper-kotlin-sdk
./gradlew publishToMavenLocal

Once Maven Central is wired up, drop the mavenLocal() line.

What it shows

• How to construct a client with Client.create(token)
• One authenticated call: ch.user.get() (suspend function, returns JsonElement?)
• One market-data call: ch.exchange.ticker(exchange = ..., market = ...)
• Typed error handling via catch (e: CryptohopperError)

Where to get a token

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

Dependencies

• com.cryptohopper:cryptohopper — the SDK itself.
• kotlinx-coroutines-core and kotlinx-serialization-json — both are transitive deps of the SDK; declared explicitly here so Gradle resolves them at compile time.

Requires JDK 17+.
