Fusio Worker API

The Fusio Worker API enables executing API action logic in multiple programming languages by forwarding requests to external worker processes. Workers are implemented in the target language (JavaScript, Python, Java, PHP, etc.) and communicate with the Fusio core via a simple REST interface, enabling serverless deployments.

x-base-url-note: Templated on purpose. A worker is a container the operator runs alongside Fusio, so its
  host is theirs; the port is the one the provider's own docker-compose publishes per language (java 9090,
  javascript 9091, php 9092, python 9093). This entry tracks the PHP worker.
