# Introduction

> Vatic API — price targets, Hyperliquid prediction market data, fee calculators, and order management for systematic prediction market trading.

## 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.
* **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.
* **Fee calculators** — both the legacy formula and the April 2025 Polymarket fee structure, with full trade estimates.
* **Order management** — place, list, and cancel Polymarket CLOB orders authenticated via your trading wallet.
