getInflationReward

getInflationReward returns the actual SOL staking rewards that specific Solana stake accounts earned during a given epoch. Where getInflationRate tells you the network-wide rate, this method tells you what real lamports landed in each account when an epoch's rewards were paid out. Send a JSON-RPC 2.0 POST with positional params — an array of base-58 stake account addresses followed by an optional config object — to https://solana.therpc.io/YOUR_API_KEY. For each address the node returns an entry containing epoch, effectiveSlot (the slot the reward took effect), amount (the reward in lamports), postBalance (the account balance after the payout), and commission (the validator commission applied), or null if that account earned no reward in the requested epoch.

Use cases

• Report the SOL staking rewards a set of stake accounts earned in a specific epoch — useful for tax exports, treasury accounting, or per-validator performance reports.
• Reconcile reward payouts in a delegator dashboard by matching each amount (in lamports) against postBalance so users can see their stake growing epoch by epoch.
• Account for the validator's cut by reading commission on each entry: the amount is already net of commission, and the field tells you how much the validator retained.

Errors & troubleshooting

Common pitfalls

• Pass stake account addresses, not ordinary SOL wallet addresses. Inflation rewards accrue to the stake account that holds the delegation; a regular wallet pubkey will return null even if it owns staked SOL.
• A null entry simply means that account earned no reward in the requested epoch (for example it was not yet delegated or was deactivating). Handle nulls per address instead of assuming every entry is populated.
• Omit the epoch config field to query the most recently completed epoch; set it explicitly when you need rewards for a particular historical epoch.
