Explorer-backend

Spacemesh explorer backend designed to provide data for explorer-frontends

Explorer Software Architecture

Using the Explorer Backend API

The explorer backend provides a public REST API that can be used to get data about a Spacemesh network. Follow these steps to use the API for a public Spacemesh network:

1. Obtain a currently available explorer API endpoint from the Spacemesh public web services endpoint. This endpoint lists all available Spacemesh networks such as testnets.
2. Build a REST request using the endpoint. For example, if the explorer api url for net-id 28 is https://explorer-api-28.spacemesh.io/ then the network-info data is available at https://explorer-api-28.spacemesh.io/network-info.
3. Issue an http 'GET' request to get the data. e.g. curl https://explorer-api-28.spacemesh.io/network-info.
4. Live long and prosper.

Paging and pagination

• Use the pagesize and page params to get paginated results. The first page number is 1, so for example, to get the first 20 accounts on TN 128 call: https://explorer-api-28.spacemesh.io/accounts?pagesize=20&page=1 and to get the next 20 accounts use: https://explorer-api-28.spacemesh.io/accounts?pagesize=20&page=2
• API results which support pagination include pagination data in the response json. e.g.:

{"totalCount":1020,"pageCount":51,"perPage":20,"next":2,"hasNext":true,"current":1,"previous":1,"hasPrevious":false}}

Use this pagination data to figure out how many calls you need to make and which what params in order to get all the data.

API Capabilities

The API is not properly documented yet. The best way to identity the supported API methods is via the api server source code.
