About UpDown Charts

What we cover

28 markets: seven assets — Bitcoin, Ethereum, Solana, XRP, Dogecoin, BNB and Hyperliquid — each on 5-minute, 15-minute, 1-hour and 4-hour windows. You can browse all markets for live prices and epoch history.

Every market is recorded from five pooled sources: Binance, Pyth Hermes (no data since 2026-08-26), Chainlink, the Polymarket CLOB order book, and the price-to-beat endpoint. Tick-level data is retained for 90 days, and every epoch carries its price to beat, close, outcome and final volume. HYPE's Binance and Chainlink series start on 2026-09-24, so older HYPE windows show fewer series.

How resolution works

A market resolves on price alone: if the close is at or above the open (the price to beat) it resolves UP, so an exact tie resolves UP; only a close below the open resolves DOWN. We record the outcome Polymarket settled — see what a Polymarket up or down market is for the full mechanics.

Programmatic access

Premium accounts get a REST API and a hosted MCP server over the same data set: the market catalog, paginated epoch history, full tick series per epoch, and a live snapshot per market. Keys are udc_ Bearer tokens, rate limited to 100 requests per minute and 50,000 per day. The API and MCP reference documents every endpoint, parameter and field. Plan details are on pricing.
