External Market Data

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.


Before you start

  • Authentication — Every request must be signed with your API key (X-SCX-API-KEY) plus a Signature and Timestamp.
  • Access — Market Data must be enabled for your API key. If you receive a 403, reach out to your zerohash contact to have it turned on.
  • Trading pairs — Pricing endpoints take an underlying asset (e.g. BTC) and a quoted_currency (e.g. USD), and support the assets enabled for liquidity on your account.

Integration Notes

  • Polling Frequency: Since this is a REST-only service, please ensure your integration respects the documented rate limits when fetching latest prices.
  • Enablement: These endpoints are not active by default. If you need these enabled for your platform, please contact your Integration Support Agent.
