Rate Limits

The Novant API includes several limits based on plan size and rate of requests.

Daily Usage Limit

Each project has a daily request limit based on plan size.

The current limit is 2 requests per capacity unit.

For example:

Plan	Capacity	Daily Limit
Starter Bundle	4000 caps	8000 requests/day
Pro 10K Plan	10,000 caps	20,000 requests/day
Pro 50K Plan	50,000 caps	100,000 requests/day

Once your daily request limit has been reached, future requests for that day will return 429 error responses until the window is reset the following day.

Per Key Limits

By default, all keys may consume up to the project-wide daily request limit. Project owners may optionally set a daily limit on a per-key basis under the API Keys tab on the project.

If a per-key limit is set, the once your daily request limit has been reached for that key, future requests for that day will return 429 error responses until the window is reset the following day.

Rate Limiter

The rate limiter safeguards against bursts of incoming traffic to help maximize stability. If you send many requests in quick succession, you might see error responses with status code 429.

The current limit is 1000 requests within a 5-minute sliding window.

A basic technique for integrations to gracefully handle limiting is to watch for 429 status codes and build in a retry mechanism. The retry mechanism should follow an exponential backoff schedule to reduce request volume when necessary. We’d also recommend building some randomness into the backoff schedule to avoid a thundering herd effect.
