Connect your application to Solana Mainnet RPC and the Digital Asset Standard API. Read account and transaction data, submit and simulate transactions, and request priority fee estimates. Standard JSON-RPC batches support up to 10 requests; bundle submissions use standalone requests.
Most RPC requests use 1 credit. DAS requests and getProgramAccounts use 10 credits. Each batch item counts separately. Requests forwarded to a provider count toward usage, including errors. Your keys share one allowance for the 30-day paid period. DAS has a separate rate limit; transaction submission and program-account limits also apply within the RPC limit.
Streaming is included only where a plan lists an allowance. Solana WebSockets support standard PubSub and, where listed, enhanced transaction subscriptions.

Relay is an independent service with its own API keys, limits, and dashboard. Any Helius price comparison covers matching credit allowances and RPC/DAS rate limits only. Supported methods, streaming products, support, and service guarantees differ.
Requests are rate-limited when you exceed your plan’s throughput, and stop when your credit allowance runs out. There are no automatic overage charges. Creating additional keys does not increase your account’s allowance.
