Cosmos Hub at BryanLabs

Per-source-IP limits on the Cosmos Hub mainnet RPC and REST hosts. Over-limit requests receive HTTP 429.

RPC + REST combined

1,200 requests / 60 seconds / source IP

Shared across both mainnet HTTP hosts, not 1,200 for each endpoint.

RPC search and block results

30 requests / 10 seconds / source IP

/tx_search, /block_search, and /block_results; also count toward the combined limit.

REST transaction endpoint

30 requests / 10 seconds / source IP

/cosmos/tx/v1beta1/txs; also counts toward the combined limit.

Retry-After is 60 seconds for the combined limit and 10 seconds for the path-specific limits. These HTTP rules do not cover gRPC.
