API ReferenceTiers & Rate Limits

Tiers & Rate Limits

Every API key carries a tier. The tier determines which endpoints you can call, how many REST requests per minute you get, and how many WebSocket connections you can hold open. Each tier includes everything in the tiers below it.

REST rate limits

The per-minute limit is enforced per key. Exceed it and the request returns 429 Too Many Requests — back off and retry. The free tier is for evaluation; for production traffic start at Layer 1.

WebSocket limits

WebSocket access starts at Layer 1 (Free gets 0 connections). Each tier caps both the number of concurrent connections and the subscriptions per connection (50 on Layer 1–3, unlimited on Enterprise).

Exceeding the subscription cap returns an error message on the socket; it does not disconnect you. See the WebSocket Protocol for the full lifecycle.
