Jupiter Perpetuals Borrow Rates Data Stream

Overview

Implements data streaming functionality for Jupiter Perpetuals borrow rates by fetching and transforming pool information.

Changes

  • Added getBorrowRates function that accepts an asset parameter
  • Created PerpsApiService for handling Jupiter Perps API interactions:
    • getPoolInfo: Fetches raw pool data
    • transformToMarketData: Converts pool info to market data format
  • Defined types for API responses and market data structures
  • Added test suite covering:
    • Successful rate fetching
    • Invalid asset handling
    • API error handling
    • Data transformation error handling

Testing

  • Unit tests verify both success and failure paths
  • Mocked API responses for consistent testing
  • Verified error handling for invalid inputs
