How Helius counts usage
Credits: 1 per standard RPC call; getProgramAccounts and each DAS call 10; LaserStream 2 credits per 0.1 MB. 1 credit per standard RPC call; getProgramAccounts and DAS calls are 10, so costs here are a lower bound. (source, read )
Cost of 1M calls = units per call × Helius's published price per unit. Unit prices come from the Plans table above:
- Developer: $49 ÷ 10M credits = $4.90 per 1M credits, if the whole allowance is used.
- Developer: $5 per 1M credits above the allowance.
| Call | Units per call | $ per 1M calls inside Developer ($49 ÷ 10M credits) | $ per 1M calls at Developer rate ($5 per 1M credits) |
|---|---|---|---|
| Standard RPC call (Solana) | 1 credit | 1 × $4.90 = $4.90 | 1 × $5 = $5 |
| getProgramAccounts | 10 credits | 10 × $4.90 = $49 | 10 × $5 = $50 |
| DAS API call | 10 credits | 10 × $4.90 = $49 | 10 × $5 = $50 |
Units per call from Helius's own method price list (source, read ). List prices; bandwidth, add-ons and taxes excluded.
