eth_gasPrice

eth_gasPrice asks a BNB Smart Chain node what single per-gas price it currently recommends, returned as a hex wei value priced in BNB. BSC has historically favored low, fairly stable gas, so this one-number suggestion is often all a simple sender needs. Hit https://bsc.therpc.io/YOUR_API_KEY at chain ID 56 and you get the node's view of the going rate — the figure to drop into the gasPrice slot of a legacy, type-0 transaction.

Use cases

• Take a quick read on what BSC gas costs right now before building a transaction.
• Fill the gasPrice field of a legacy type-0 BNB transaction, the simplest send a wallet can construct.
• Blend it into a fee oracle as one signal next to eth_feeHistory percentiles for a sturdier estimate.

Errors & troubleshooting

Common pitfalls

• Where EIP-1559 is active this number is derived and tends to run high; for type-2 sends reach for eth_maxPriorityFeePerGas plus eth_feeHistory instead of this single figure.
• The value is raw wei, so to show it as gwei divide by 1e9, or convert to BNB (divide by 1e18) before putting it in front of a user.
