Usage limits

This endpoint is limited to 45 requests per minute from an IP address.

If you go over the limit your requests will be throttled (HTTP 429) until your rate limit window is reset. If you constantly go over the limit your IP address will be banned for 1 hour.

The returned HTTP header X-Rl contains the number of requests remaining in the current rate limit window. X-Ttl contains the seconds until the limit is reset.
Your implementation should always check the value of the X-Rl header, and if its is 0 you must not send any more requests for the duration of X-Ttl in seconds.

We do not allow commercial use of this endpoint. Please see our pro service for SSL access, unlimited queries and commercial support.
