PHP 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
composer install
php hello.php

What it shows

  • How to construct a Client with named-argument syntax (PHP 8.0+)
  • One authenticated call: $ch->user->get()
  • One market-data call: $ch->exchange->ticker(exchange: ..., market: ...)
  • Typed error handling via CryptohopperException

Where to get a token

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

Dependencies

Just one — cryptohopper/sdk. Requires PHP 8.1+.
