## What it is
A set of PHP interfaces and abstractions for HTTP clients, extracted from the Symfony components. It lets libraries depend on stable, battle-tested contracts rather than concrete HTTP client implementations.

## Use cases
- decouple my library from a specific http client implementation
- type-hint against a standard http client interface in php
- make my package interoperable with symfony http clients
- swap http clients without changing consuming code
- define a contract for http client implementations

## When to choose
- you are building a PHP library that needs to make HTTP requests without hard-coding a client
- you want interoperability with the Symfony ecosystem
- you need stable interfaces to mock in tests

## When to avoid
- you just need an actual HTTP client to send requests - use symfony/http-client or Guzzle instead
- your project does not use PHP

## Facets
- artifact type: library
- maturity: stable
- function: http-client, sdk, developer-tools
- domain: web-development, backend, apis, developer-tools
- platform: php, cross-platform
- tags: symfony-contracts, interfaces, abstractions, decoupling, interoperability
