Consume business logic without copying source

A consumer invokes publisher-owned logic through a stable typed interface.

The problem

After code is copied, maintenance ownership, the current version, and the source of each change quickly become unclear.

What gets published

The team that maintains the logic publishes its smallest reusable function interface.

What stays local

Source, implementation dependencies, and maintenance ownership.

Business data crossing the call boundary

Typed arguments, released result, and invocation facts.

What this shows

The publisher can improve one implementation while consumers keep the same contract.

What it doesn't prove

Discovery does not imply pricing, ranking, payment, or legal marketplace terms.

Public source evidence for this case

Evidence level: Source layout and declarations are anonymously inspectable
Pinned public EasyRemote revision: 44c768ca26d0f92a5ab9d1d03342895c29c27dc6
Public inspection: Public inspection
Expected check: Required files, Python syntax, and @node.register declaration are checked without installing dependencies
Runtime invocation: Not established by this source fixture; record separate discovery, Invocation, and terminal Receipt evidence

Run in a compatible source workspace

This Provider/Client walkthrough requires compatible EasyRemote, EasyNet-Cli, and EasyNet-Axon sibling source checkouts, a compatible Hub, and a paired, running Runtime. The source is public; clean installation from public packages is not yet verified. Technical Alpha offers guided setup. Use the pinned EasyRemote revision below; this page does not pin the other components. Runtime admission still determines whether the caller may execute the function.

# From EasyRemote revision 44c768ca26d0f92a5ab9d1d03342895c29c27dc6
cd gallery/projects/04_function_marketplace
# Terminal 1
uv sync --frozen
uv run python node.py

# Terminal 2 (same project)
uv run python client.py

Connect your own function

Read the setup first. You need compatible sibling source checkouts, a compatible Hub, and a paired, running Runtime. Technical Alpha offers guided help; public-package clean installation is not yet verified.
