API Rate Limits

IP-Based Rate Limits

All REST API requests consume weight from a fixed 1-minute window. Once the total weight consumed within the window reaches the limit, subsequent requests are rejected until the window resets.

Endpoints not listed below default to weight 20.

Dynamic Weight Rules

Orderbook Depth

Depth (limit)	Weight
≤ 100 (default)	5
101 – 500	10
> 500	20

Batch Order Formula

weight = 1 + floor(batch_size / 40)

Batch size	Weight
1 – 39	1
40 – 79	2
80 – 119	3

History Extra Weight

History endpoints incur additional weight after the response, based on items returned:

extra_weight = floor(items_returned / 20)

---

Order Placement Limits

Separate from the weight budget:

Client type	Limit	Scope
API key	1200 orders / minute	per (account, API key)
Web (no key)	60 orders / minute	per account

---

WebSocket Limits

Separate from the REST weight budget:

Limit	Value
Concurrent connections per IP	10
New connections per IP per minute	30
Subscriptions per IP (all connections)	1000
Unique users per IP	10
Messages per IP per minute	2000
Messages per connection per minute	2000
Inflight requests per IP	100

---

Address-Based Rate Limits

Address-based limits apply per user address and only affect actions (order placement, cancellation, etc.), not info/query requests.

The rate limiting logic allows 1 request per 1 USDC traded cumulatively since address inception. For example, with an order value of 100 USDC, this requires a fill rate of 1%. Each address starts with an initial buffer of 10,000 requests.

When rate limited, an address is allowed one request every 10 seconds.

Cancels have a higher cumulative limit to ensure open orders can always be wound down:

cancel_limit = min(limit + 100000, limit * 2)

where limit is the default limit for other actions.

Each user has a default open order limit of 1000 across all symbols combined (spot + perps).

---

Batched Requests

A batched request containing N orders (or cancels) is counted differently depending on the rate-limit dimension:

Dimension	Counted as
IP-based weight	1 request (weight per the batch formula above)
Address-based limit	N requests (one per order/cancel in the batch)
