This API is rate limited. You can only query the API Service up to 100 times per minute per API Key. We reserve the right to adjust the rate limit for given endpoints to provide a high quality service for all clients.
If the rate limit is exceeded, WhosOnLocation will respond with a HTTP 429 Too Many Requests response code and a body that details the reason for the rate limiter kicking in. The response will also have a Retry-After header that tells you how many seconds to wait before retrying.
