The Market Data API gives you real-time pricing, historical price history, and crypto news for the assets supported on the zerohash platform. Use it to power price tickers, charts, asset detail pages, and in-app news feeds - without standing up your own market data pipeline.
All endpoints are read-only (GET), live under the /market_data/ path, and use standard zerohash API-key authentication.
Pricing & market stats
- Symbol Data : A live snapshot for a trading pair: latest price, 24-hour / daily / hourly highs, lows, and changes, trading volume, market cap, and circulating supply. Ideal for tickers and asset overview pages.
- OHLCV : Historical open / high / low / close / volume candles for a pair, at minute, hourly, or daily granularity. Use it to render charts and run analysis.
News
- Latest News — A feed of crypto news articles, filterable by source, category, language, and recency. Drop a relevant news stream into any asset or market view.
- News Feeds — The list of available news sources, so you can build source filters.
- News Categories — The list of available categories (e.g. by asset), so you can build category filters.
