getInflationGovernor

getInflationGovernor reads the governing constants behind Solana's SOL inflation schedule — the protocol-level dials that decide how new SOL is minted to reward stakers over the network's lifetime. Send a JSON-RPC 2.0 POST with positional params to https://solana.therpc.io/YOUR_API_KEY and the node returns the inflation governor parameters: initial (the starting annual inflation rate), terminal (the long-run floor it tapers toward), taper (the yearly rate of reduction), foundation (the share of inflation directed to the foundation), and foundationTerm (how many years that foundation share lasts). These are fixed protocol settings rather than a live measurement, so the response changes only on a genuine protocol change.

Use cases

• Model how SOL inflation tapers year over year in a staking calculator: start from initial, apply taper each year, and converge toward terminal to project future staking yield.
• Read the foundation and foundationTerm values for tokenomics analysis — they tell you what slice of newly minted SOL goes to the foundation and for how long, so you can separate staker rewards from foundation issuance.

Errors & troubleshooting

Common pitfalls

• These are the governing parameters of the inflation curve, not the rate in effect right now. To get the actual inflation Solana is applying for the current epoch, call getInflationRate instead — getInflationGovernor only describes the schedule that rate is derived from.
