Rate Limits

YCharts enforces two different kinds of rate limits to our API.

Burst Rate Limit	Sustained Rate Limit
10 requests per second	10,000 requests per hour

Exceeding either of these rate limits will result in a 429 Error Code like the following:

{
    "meta": {
        "error_message": "Request was throttled. Expected available in 30 seconds.",
        "error_code": 429,
        "url": "https://api.ycharts.com/v3/companies",
        "status": "error"
    },
    "response": {}
}

If you encounter an error message like this, please wait the appropriate amount of time before querying our API again.
