Rate Limits

Rate limits protect service quality for all users. Limits vary by plan and are enforced per API key.

Limits by Plan

Plan	Requests/Day	Rate Limit	Burst
Trial	1,000	30/min	45
Starter	10,000	120/min	180
Pro	100,000	600/min	900
Enterprise	1,000,000	6,000/min	9,000
Pay-As-You-Go	Unlimited	600/min	900

Rate Limit Headers

Every API response includes headers showing your current usage:

response headers

X-RateLimit-Limit: 300
X-RateLimit-Remaining: 287
X-RateLimit-Reset: 1711029660
X-RateLimit-Window: 60

X-RateLimit-Limit — Maximum requests per window
X-RateLimit-Remaining — Requests remaining in current window
X-RateLimit-Reset — Unix timestamp when the window resets
X-RateLimit-Window — Window duration in seconds

When You Hit the Limit

Requests exceeding the rate limit receive a 429 Too Many Requests response:

429

{
  "error": "Rate Limited",
  "message": "Rate limit exceeded. Retry after 60 seconds",
  "code": 429,
  "retry_after": 60
}

Tip: Use the Retry-After header value to implement exponential backoff in your client.

Best Practices

Cache responses locally

Indicator values don't change within their timeframe. Cache responses and only re-fetch when a new bar opens.

Use batch endpoints

Use /v1/multi for multiple symbols instead of making individual requests.

Implement backoff

On 429 responses, wait for the Retry-After period before retrying. Use exponential backoff for consecutive failures.

Monitor your usage

Track usage in your dashboard. Set up alerts at 50%, 80%, and 100% of your quota.

Overage Billing

Subscription users who exceed their daily limit are billed at Pay-As-You-Go rates. Set a spending cap in your dashboard to prevent unexpected charges.
