What is Vatic API?

Vatic API is a production-grade backend for prediction market trading. It currently provides:
  • Polymarket price targets — opening prices for BTC, ETH, SOL, XRP, HYPE, DOGE, and BNB sourced from Chainlink Data Streams and Binance Futures OHLCV.
  • Chainlink TWAP resolution references — 30s and 60s TWAP reports for Polymarket crypto up/down resolution testing and backtesting.
  • Hyperliquid prediction market discovery — authenticated access to active outcome contracts, official trade slugs, parsed target prices, expiry windows, and live yes/no side pricing.
  • Market timestamps — all window boundaries for a given day and interval, with Polymarket slugs and URLs pre-built.
  • Order management — place, list, and cancel Polymarket CLOB orders authenticated via your trading wallet.
