Changelog

Notable changes to the Sparky Perpetual Contracts API and this documentation. Newest first.

2026-09-16​

  • Docs: Initial Sparky developer documentation site. Ported the Docusaurus skeleton, theme and page conventions from the previous developer portal and rewrote every page against Sparky's backend (/fapi/v1/*, /fapi/v2/*, /futures/data/*, /api/v1/* and the /ws WebSocket). Every Binance USDT-M endpoint has a page; the ones Sparky does not serve are marked Not yet implemented. New sections: EVM chains & accounts, Deposits & withdrawals, Sparky-specific Endpoints (API keys, userTrades/slippage, algoOrder family, listenKey, sharded routing, symbol aliases, native market API, health, errors), Market Data Streams documenting the real /ws protocol, and the Referral, Points and Earn sections.
  • Docs: Base URLs are placeholders (https://api-avax.<sparky-domain> etc.) until the production hostnames are assigned; one deployment per chain (Avalanche 43114, Arbitrum 42161, BNB 56, Fuji 43113, Arbitrum Sepolia 421614).
