The API is rate limited to 100 requests per 2 minutes for each user (actually for each originating IP address).
We are still working on establishing the exact rate limits. Please let us know if you encounter the rate-limiting and in what use cases.
If a request is rate-limited, we include headers describing the current rate limit status:
X-RateLimit-Limit: 100 X-RateLimit-Remaining: 0 X-RateLimit-Reset: 120
X-RateLimit-Limit - Total number of requests allowed for current periodX-RateLimit-Remaining - Remaining requests for current period (typically 0)X-RateLimit-Reset - Number of seconds until the the requests count resets and you can do request againIf the rate limit is hit, the API will return a 429 Too Many Requests status code. In this situation, your application should not send any further requests until X-RateLimit-Reset seconds have elapsed.
