Rate Limits

Free users of the RPC Node are rate limited to 7500 API credits every 5 seconds per project. Each JSON-RPC method uses an assigned amount of API credits per call. The average JSON-RPC call API credit value is 30, so expect approximately a 50 RPS maximum.

If you would like a higher limit, reach out to us in our Node Discord channel to request a bumped limit. Builders get a free rate limit bump. CDP currently doesn’t have a paid tier for RPC Node.
