Rate limits

The Parti API applies per-wallet and per-IP rate limits.

Bucket	Limit	Applies to
Per-wallet order placement	50 / 60s	POST /v1/orders (keyed on session user)
Per-IP	600 / 60s (≈10/s)	/v1/orders/*, /v1/withdraw-signed
Per-IP	60 / 60s	/v1/events (writes) + administrative endpoints
Deposit service robinhood-address	30 / 60s (per-IP)	GET /v1/deposit/robinhood-address/{user}

Exceeding a bucket returns:

{ "error": "rate_limited", "retry_after": <secs> }

with HTTP 429. Back off for retry_after seconds before retrying.

Trading pauses

Trading may be temporarily paused. When paused, POST /v1/withdraw-signed is blocked before any other check, and new orders queue while resting orders stay live.
