Flow Access API rate limits on Dapper Labs Access nodes
Rate limits
Following are the current rate limits for the Access Node gRPC API in total across all Dapper Labs Access nodes. The actual limits are enforced by each individual node. If you are using a load balanced endpoint, the limits below are the max rate, and may vary depending on how your requests are routed.
Once the limit has reached, the client will receive an RPC error ResourceExhausted in the gRPC response.
Please note, these limits only apply to the access nodes hosted by Dapper Labs. Access nodes run by other node operators will have different rate limits.

The rate limits are the same for the gRPC web interface
The rate limits for ALL the REST API is 40 request per second per client IP
Please note: The rate limits are applied by each of the access nodes behind a load balancer and limits listed here are the aggregate total from all the access nodes. Actual limits may be somewhat less depending on how the requests are routed.
