Does NOT serve Metaplex DAS (getAsset*, searchAssets), so DAS-heavy workloads cannot be costed on dRPC at all. Free tier is 210M CU per 30 days (~10.5M calls) but is served over dRPC's public node pool, which is slower and less reliable than paid endpoints. Volume discounts exist above the standard rate but are not published. dRPC does not serve Metaplex DAS on Solana — the methods are absent from its Solana API."

Full ladder: Developer $0 (3M RU, 25 RPS, $20/M), Growth $49 (20M, 250 RPS, $15/M), Pro $199 (80M, 400 RPS, $12.50/M), Business $499 (200M, 600 RPS, $10/M), Enterprise $990+ (400M+, unlimited, $5/M). No Solana per-method RU weighting — every method is 1 RU. 'archive' is a pseudo-method: on Solana it applies to exactly eight methods (getTransaction, getBlock, getBlockTime, getBlocks, getBlocksWithLimit, getSignaturesForAddress, getFirstAvailableBlock, getSignatureStatuses) and only when the slot is below firstAvailable + 5,000, so history near the chain tip bills at 1 RU. getSignaturesForAddress and getFirstAvailableBlock are always archive. Free tier 3M RU/mo at 25 RPS. Per-method RPS caps below plan level: getSupply 2 (paid only), getTokenAccountsByOwner 80, getBlock 400, getBlockTime/getBlocks/getBlocksWithLimit 500.
