Collection of RESTful APIs provided by Ethereum consensus keymanagers
API browser: https://ethereum.github.io/keymanager-APIs/
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 related to validation duties (e.g. Attestations, and Beacon Blocks) as well as state changes (e.g. Exits).
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.

Further detail on expected behavior and error states of the APIs are listed in the Flows Doc
To render the spec in a browser you will need an HTTP server to serve the index.html
file.
Rendering occurs client-side in JavaScript, so no changes are required to the HTML file between
edits.
python2 -m SimpleHTTPServer 8080
The API spec will render on http://localhost:8080.
npm install simplehttpserver -g
# OR
yarn global add simplehttpserver
simplehttpserver
The API spec will render on http://localhost:8000.
The API spec is linted for issues before PRs are merged.
To run the linter locally, install spectral
:
npm install -g @stoplight/spectral
# OR
yarn global add @stoplight/spectral
and run with
spectral lint keymanager-oapi.yaml

Create and push a tag
- Make sure info.version in keymanager-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).
Entries should be in the following format (replace <tag>
with the real tag name from step 1):
{url: "https://github.com/ethereum/keymanager-APIs/releases/download/<tag>/keymanager-oapi.yaml", name: "<tag>"},
