LaserStream Data Metering: Billing is based on uncompressed gRPC message size, not the compressed data your client receives. Typical sizes for updates: Block (~4MB), Account (~0.0004MB), Transaction (~0.0006MB).

Webhook Billing: You are charged 1 credit when Helius processes and sends a webhook event to your endpoint. This charge applies regardless of whether your endpoint successfully receives or processes the webhook.

MethodCreditsDescription
Sender0Ultra-low latency submission
Unstaked Connections1May be unreliable during congestion
Staked Connections10Highest reliability (default)

Staked Transactions Are Now Default: All transactions via mainnet.helius-rpc.com automatically use staked connections for highest success rates.
