Solana limits
All numbers below come from tier-matrix.yaml. Enterprise RPS is unlimited.
Endpoint and plans: Solana RPC endpoint.
Values are sustained RPS / short burst capacity. The included 2× burst buffer absorbs brief traffic spikes at no extra cost and refills at the sustained rate. There is no quota on the number of bursts. Size ongoing traffic to sustained RPS; unlimited categories have no numeric burst ceiling. See Burst capacity.

The matrix also gates sol_das and streaming features, but it does not assign
them numeric RPS values. Sustained RPS has a 2x burst. See
