Rate Limits

Every plan has two limits: requests per minute and requests per month. Both apply to your account, so all of your API keys and your MCP server calls share them.

Limits by plan

How the limits work

• •The per-minute limit uses a sliding 60-second window.
• •Each data request counts as one toward your monthly quota. The quota resets at 00:00 UTC on the 1st of each month.
• •Free includes search, prices, financial statements, metrics, insider trades, and SEC filings. That covers every MCP tool.

When you hit the per-minute limit

The API returns 429 with a Retry-After: 60 header. Wait for the window to clear, then retry.

HTTP/1.1 429 Too Many Requests
Retry-After: 60

  "detail": "Rate limit exceeded: 100 requests per minute on the Free plan."
}

When you use your monthly quota

The API returns 429 with X-Quota-Limit, X-Quota-Remaining, andX-Quota-Reset headers. Retry-After is the number of seconds until the reset.
