Rate limits

Our reference API allows each IP address up to:

100 concurrent connections.
100 corporate actions requests per second.
100 adjustment factors requests per second.
100 security master requests per second.

When a request exceeds a rate limit, a BentoClientError exception is raised with a 429 error code.

Retry-After

The Retry-After response header indicates how long the user should wait before retrying.

If you find that your application has been rate-limited, you can retry after waiting for the time specified in the Retry-After header.

If you are using Python, you may use the time.sleep function as seen below to wait for the time specified in the Retry-After header. e.g. time.sleep(int(response.headers("Retry-After", 1)))

This code snippet works best for our current APIs with their rate limits. Future APIs may have different rate limits, and might require a different default time delay.
