Plans and payments

Review current allowances and understand how a SOL payment creates a paid period.

Current plans

These are the current public offers for a new purchase. Your active period keeps its purchased terms; check the dashboard for your account’s allowance and end date.

Plan	Price / 30 days	Credits	API keys
Developer	$24.50	10,000,000	2
Business	$249.50	100,000,000	5
Professional	$499.50	200,000,000	10

Plan	RPC / sec	DAS / sec	Send / sec	Program accounts / sec	Bundles / sec
Developer	50	10	5	25	0
Business	200	50	50	50	5
Professional	500	100	100	75	5

Transaction submission and program-account limits sit within the RPC limit. DAS is separate. All keys share these limits.

Included HTTP features

Paid HTTP access supports these features within your purchased limits:

Solana Mainnet RPC for supported account, block, and transaction queries.
Digital Asset Standard methods for token and NFT data.
Transaction simulation and priority fee estimates.
JSON-RPC batches of up to 10 supported requests, excluding sendBundle.
API key creation, renaming, revocation, usage tracking, and HTTP request history.

View supported methods for the exact RPC contract. Bundle submission requires a positive purchased bundle limit. Streaming allowances are listed separately below.

Streaming allowances

Plan	WebSocket	gRPC	Preprocessed
Developer	1 connections / 10 subscriptions Enhanced subscriptions included	1 streams / 4 filters Devnet	1 connections / 1 subscriptions
Business	1 connections / 10 subscriptions Enhanced subscriptions included	1 streams / 4 filters Mainnet + Devnet	1 connections / 1 subscriptions
Professional	1 connections / 10 subscriptions Enhanced subscriptions included	1 streams / 4 filters Mainnet + Devnet	1 connections / 1 subscriptions

Positive streaming caps require an enabled service; use the separate endpoints in the Streaming guide.

Pay with SOL

Open Plans, select an offer, and review the time-limited SOL quote. Prices are listed in USD; checkout fixes the SOL amount for that quote. Review the network fee in your wallet before approving.

Your first 30-day period begins after a Mainnet payment is finalized. Renewals and plan changes are queued after existing paid periods, with their own allowances. A queued purchase does not refill or change the current period.

There is no automatic renewal or automatic overage charge. A devnet test payment does not activate Mainnet RPC access. If confirmation is delayed, check the existing checkout’s status before starting another payment.

Relay and upstream products

Relay is an independent service with its own keys, purchased allowances, gateway contracts, and support. Matching credit or rate-limit figures do not imply the full feature set of a Helius plan.

Helius describes separate network, streaming, Shred, and data add-on entitlements in its plan documentation. Those entitlements and prices are not additional Relay offers. Use the Relay tables above and the supported API reference to determine what your purchase includes.
