Ethereum keymanager APIs

Warning: Super fresh repo, expect rapid iteration and breaking changes

Collection of RESTful APIs provided by Ethereum consensus keymanagers

API browser: https://ethereum.github.io/keymanager-APIs/

Outline

This document outlines an application programming interface (API) which is exposed by a validator client implementation which aims to facilitate validator management tools without sacrificing security.

The API is a REST interface, accessed via HTTP. The API should not, unless protected by additional security layers, be exposed to the public Internet as the API includes multiple endpoints which can control the state of a deployed validator (e.g. Exits, etc). Currently, the only supported return data type is JSON.

The validator client (VC) maintains private information related validators such as keys and an anti-slashing database. A VC is also in charge of signing messages relatied to validation duties (e.g. Attestations, and Beacon Blocks) as well as state changes (e.g. Exis).

The goal of this specification is to promote interoperability between various validator client implementations to aid in the creation of common validator management tools such as GUIs, alerts, etc.

Render

To render spec in browser you will need any http server to load index.html file in root of the repo.

Python

python -m SimpleHTTPServer 8080

And api spec will render on http://localhost:8080.

NodeJs

npm install simplehttpserver -g

# OR

yarn global add simplehttpserver

simplehttpserver

And api spec will render on http://localhost:8000.

Contributing

Api spec is checked for lint errors before merge.

To run lint locally, install linter with

npm install -g @stoplight/spectral

# OR

yarn global add @stoplight/spectral

and run lint with

spectral lint beacon-node-oapi.yaml

Releasing

Create and push tag
- Make sure info.version in beacon-node-oapi.yaml file is updated before tagging.
- CD will create github release and upload bundled spec file
Add release entrypoint in index.html

In SwaggerUIBundle configuration (inside index.html file), add another entry in "urls" field (SwaggerUI will load first item as default). Entry should be in following format(replace <tag> with real tag name from step 1.):

         {url: "https://github.com/ethereum/keymanager-APIs/releases/download/<tag>/beacon-node-oapi.yaml", name: "<tag>"},
