Filtering happens before the wire
Filters are applied per client on our side, so the bytes you pay for and parse are the ones you asked for. Subscribing broadly and discarding on receipt wastes bandwidth and your own CPU, and it is the usual reason a gRPC consumer falls behind.
Tail latency is the number that matters
A good median hides a bad tail, and it is the tail that breaks a strategy. <5ms p50, 8ms p95 and 12ms p99 at 180k msg/s.
Try it on the free tier
Yellowstone gRPC streams are part of the free plan, along with a 10 GB gRPC data pack you can claim every 30 days. That is enough to run a real consumer against real traffic before you commit to a seat.
Frequently asked
Is Yellowstone gRPC available for free?
Yes. The free plan includes Yellowstone gRPC streams and a 10 GB gRPC data pack, claimable every 30 days, with no card required.
What can I subscribe to?
Accounts, slots, transactions and blocks, with per-client filters so you only receive the subset you asked for.
Does a gRPC seat include RPC?
Yes. RPC access is included with Yellowstone gRPC, so you do not need a separate plan for standard JSON-RPC calls.
Can I get data earlier than a block subscription?
Yes, by reading shreds instead of blocks. Our decoded shreds product delivers Yellowstone-shaped updates one leader slot earlier.
