Data sources
The client application would need the obtain the data from the following sources:
Data sources
Indexer
The Indexer aggregates blockchain data to provide a Web2 interface for client applications. Clients access updated market data, order books, and user account information through REST and WebSocket endpoints. All data from the Indexer is read-only.
Node Client
The client application submits transactions to the blockchain through the validator and also reads data from it. It uses v4-client-js functions to streamline read and write operations.
Metadata Service
Static market data, including market icons, names, and various URLs, can be retrieved from this REST service. There are two endpoints (use POST instead of GET):
metadata-service/v1/info: Returns a list of market metadata:
curl --request POST 'https://66iv2m87ol.execute-api.ap-northeast-1.amazonaws.com/mainnet/metadata-service/v1/infometadata-service/v1/prices: Returns a list of spot market pricing information. Sample curl request:
