Rate limits

Pacifica uses a credit-based rate limiting system with a 60-second rolling window.

Credit Quotas

The API config key system allows Pacifica to provision higher rate limits to verified users, ensuring real traders have adequate resources while protecting against abuse.

Tier	Base Credits/60s
Unidentified IP	125
Valid API Config Key	300

These are base quotas and may be increased based on account reputation.

Credit Costs

Action	Unidentified IP	API Config Key
Standard request/action	1	1
Order cancellation	0.5	0.5
Heavy GET requests	3–12	1–3

When credits are exhausted, requests return HTTP 429.

WebSocket Limits

• Max 300 concurrent connections per IP

• Max 20 subscriptions per channel per connection

Checking Your Quota
