Substreams Atomic API

REST API

Pathname	Description

Requirements

• Clickhouse

Additionnaly to pull data directly from a substream:

• Substreams Sink Clickhouse

Quickstart

$ bun install
$ bun dev

Expected database structure

substreams-sink-clickhouse auto generates some tables (see Database structure section).
For this API to work, you will also need to provide following schemas to substreams-sink-clickhouse (see Schema initialization section):

• substreams-atomicmarket-sales schema
• substreams-atomicassets schema

The expected added tables to the database structure will then be:

erDiagram
    Sales }|--|{ Assets : " "

    Sales {
        sale_id     UInt64
        trx_id      String
        asset_ids   Array(UInt64)
        listing_price_amount  Int64
        listing_price_precision  UInt8
        listing_price_symcode    String
        listing_price_value      Float64
        collection_name String

    }

    Assets {
        asset_id     UInt64
        scope        String
        collection_name String
        template_id  Int32

    }
