Short answer: Since November 1, 2026, every Coinranking API plan includes real-time price streaming over WebSocket and Server-Sent Events (SSE), including the free plan. Before, streaming was only on the Professional plan at $199 a month. Free keys can now open 1 stream with updates every 60 seconds, and paid plans add more connections and faster updates.
What’s new
Until now, live price streams needed the Professional plan. From November 1, 2026, they work on every plan:
- Free: start streaming without a credit card
- Basic, Startup and Growth: more connections and faster updates at lower prices
- Professional: the most connections and the lowest cost per message
Both WebSocket and SSE are included on every plan.
Streaming limits per plan
| Plan | Price | Connections | Fastest updates | Credits per message |
|---|---|---|---|---|
| Free | $0 | 1 | Every 60 seconds | 0.05 |
| Basic | $24 a month | 2 | Every 10 seconds | 0.025 |
| Startup | $49 a month | 5 | Every 5 seconds | 0.01 |
| Growth | $99 a month | 10 | Every second | 0.005 |
| Professional | $199 a month | 20 | Every second | 0.0025 |
WebSocket and SSE connections share the same limit. You can choose a slower update interval to send fewer messages.
How streaming credits work
- One balance: REST calls and streaming use the same monthly credits
- Pay for data only: only delivered price messages use credits
- Free control messages: connecting, heartbeats, acknowledgements and errors cost 0 credits
- Need more? Paid plans can buy prepaid credits or set up automatic top-ups
See the credit guide for the full rules.
WebSocket or SSE?
Use SSE if your app only needs to receive prices, such as a ticker or a dashboard. Use WebSocket if you want to change your coin list while the connection stays open.
