FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package phemex-php
Phemex PHP
A typed PHP client for the Phemex exchange API. Drop it into any PHP 8.1+ project, and if you're on Laravel 10–13 it just works — no extra setup.
I got tired of hand-rolling cURL calls, computing HMAC signatures, and bolting on retry logic every time I touched the Phemex API. So this library does all of that for you and hands back a clean, object-oriented interface. You write strategy; it handles the plumbing.
What's in the box
- Runs anywhere. The core is plain PHP 8.1+ built on PSR-18 — no framework required.
- Laravel, out of the box. Auto-discovered service provider, publishable config, and a
Phemexfacade. - Signing you don't think about. Private endpoints get HMAC SHA256 signatures automatically, straight from Phemex's own algorithm.
- Your HTTP client, your rules. Guzzle ships by default, but swap in any PSR-18 implementation you like.
- Responses that won't break. Return values are DTOs that keep the raw payload around, so when Phemex adds a field, you can still reach it.
- Retries handled for you. Rate limits (HTTP 429) and flaky server errors are retried with exponential backoff.
- Exceptions that make sense.
AuthenticationException,RateLimitException,NotFoundException,ValidationException, andApiException. - Real-time when you need it. Optional WebSocket streams via
ratchet/pawl.
Installation
Laravel
The service provider is auto-discovered, so there's nothing to register. Publish the config file whenever you want to tweak the defaults:
Then set your environment variables:
Configuration
After publishing, config/phemex.php contains:
Prefer your own PSR-18 client — maybe with custom middleware, logging, or metrics? Just bind it in a service provider:

Running the tests
Everything runs against a mocked HTTP client, so you don't need an API key or a network connection to run the suite.
