Flow Access API rate limits
Following are the current rate limits for the Access Node gRPC API in total across all public access nodes.
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 public (community) access nodes.
Mainnet
The public access nodes are hosted by QuickNode.
If you require higher limits, you can either run your own Access node (see this guide) or use QuickNode to run a fully-managed access node.
| gRPC API | Total requests per second per client IP |
|---|---|
| flow.access.AccessAPI/Ping | 100 |
| flow.access.AccessAPI/GetLatestBlockHeader | 100 |
| flow.access.AccessAPI/GetBlockHeaderByID | 100 |
| flow.access.AccessAPI/GetBlockHeaderByHeight | 100 |
| flow.access.AccessAPI/GetLatestBlock | 100 |
| flow.access.AccessAPI/GetBlockByID | 100 |
| flow.access.AccessAPI/GetBlockByHeight | 100 |
| flow.access.AccessAPI/GetCollectionByID | 100 |
| flow.access.AccessAPI/SendTransaction | 50 |
| flow.access.AccessAPI/GetTransaction | 100 |
| flow.access.AccessAPI/GetTransactionResult | 100 |
| flow.access.AccessAPI/GetAccount | 100 |
| flow.access.AccessAPI/GetAccountAtLatestBlock | 100 |
| flow.access.AccessAPI/GetAccountAtBlockHeight | 100 |
| flow.access.AccessAPI/ExecuteScriptAtLatestBlock | 5 |
| flow.access.AccessAPI/ExecuteScriptAtBlockID | 5 |
| flow.access.AccessAPI/ExecuteScriptAtBlockHeight | 5 |
| flow.access.AccessAPI/GetEventsForHeightRange | 30 |
| flow.access.AccessAPI/GetEventsForBlockIDs | 30 |
| flow.access.AccessAPI/GetNetworkParameters | 100 |
| flow.access.AccessAPI/GetLatestProtocolStateSnapshot | 100 |
The rate limits are the same for the gRPC-web interface and the REST API
Testnet
The public access nodes are hosted by Flow Foundation.

The rate limits are the same for the gRPC-web interface and the REST API
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.
