Standard Relayer API Open API Spec

Usage no npm install needed!

<script type="module">
  import 0xSraSpec from 'https://cdn.skypack.dev/@0x/sra-spec';



Contains the Standard Relayer API OpenAPI Spec.

The package distributes both a javascript object version and a json version.

A deployed ReDoc static site with the API can be found here http://sra-spec.s3-website-us-east-1.amazonaws.com/.


import { api } from '@0x/sra-spec';


yarn install


You can start a development server that will serve a ReDoc documentation instance. It uses the api.json file from lib/ (you must have built at least once with yarn build or yarn build-json) that is based on the api object exported from src.

yarn watch_without_deps

The process will watch for changes, but will not hot-reload so you must refresh the page to see the changes.
