Rate Limiting

API requests are rate-limited per API key using a token bucket algorithm.

Default Limits

PlanRequests per Minute
Early Access100

Response Headers

Every authenticated response includes rate limit headers:

HeaderDescription
X-RateLimit-LimitMaximum requests per minute for your key
X-RateLimit-RemainingRemaining requests in the current window
Retry-AfterSeconds until the next request is allowed (only on 429 responses)

Rate Limit Exceeded

When you exceed your rate limit, the API returns 429 Too Many Requests:

{
"error": "rate_limited",
"detail": "100 requests per minute",
"retry_after_secs": 3
}

Best Practices

  • Cache results when the same trade parameters are being re-evaluated within a short window
  • Use batch validation to validate multiple trades in a single request instead of making individual calls
  • Implement exponential backoff when receiving 429 responses
