Frequently asked questions

What is the TickerLayer Crypto Data Feed?

The Crypto Data Feed offers REST and WebSocket access to supported digital asset pairs. It fits crypto dashboards, portfolio tools, trading analytics, alerting systems, and internal monitoring, anywhere you want fast crypto market context without running your own streaming infrastructure.

Which crypto pairs can I access?

The feed covers the major pairs and expands based on demand. Use the crypto symbols endpoint to pull the current list of supported pairs, display names, and integration-ready symbols, so your app stays in step with real coverage instead of a static list that goes stale.

Can I stream crypto market data?

Yes. WebSocket channels carry quote and trade-style updates where available, and REST sits alongside them for snapshots, initial page loads, fallbacks, and request-based work. That combination covers everything from live price cards and watchlists to backend monitoring services.

Is the Crypto API easy to integrate?

Yes. Simple routes, clear JSON, and copy-pasteable examples mean you can test in minutes. It works equally well for a quick prototype and a production dashboard, with the common integration path kept obvious so you are not reverse-engineering the API to get started.

How should developers handle crypto data freshness?

Crypto moves fast, so always read response timestamps, handle stale values safely, and plan for network or market interruptions. The structured responses make those checks easy, and in production you should pair them with sensible loading and error states, retries, and monitoring so users always see trustworthy prices.

What can I build with the Crypto Data Feed?

Common builds include price trackers, live dashboards, portfolio views, alerting tools, market overview pages, and multi-asset fintech products. Reach for WebSocket when the experience is live and REST for controlled backend requests and initial loads. The same feed scales from a weekend prototype to a full product.
