Limits & fair use
Aeon Feed is free and runs on a single server paid for out of pocket. These limits keep it fast for everyone:
| Limit | Value |
|---|---|
| WebSocket connections per IP | 10 (IPv6: per /64 prefix) |
| Channels per connection | 200 |
| Max client message size | 4 KB |
| Ticker updates | Real-time (every change, as it happens) |
| Aggregate update interval | 1 s |
| Idle timeout | 90 s without any traffic |
| REST requests | 120 / minute / IP (IPv6: per /64) |
Be a good citizen
- Use one connection and subscribe to many channels on it, rather than one connection per pair.
- Subscribe only to what you show. If you only need prices,
agg:*gives you all 100 pairs in one channel. - Disconnect background tabs. The website closes its socket 30 s after a tab is hidden.
- Back off on reconnect. Use exponential backoff with jitter and never reconnect in a tight loop.
No guarantees
The service is provided as-is, with no SLA. Prices come straight from exchange feeds and can be wrong, delayed or missing. All data is for informational purposes only and is not investment advice. Do not use it as the only input for trading decisions. See the full terms of use.
