How this service works
Pay-per-request access to CoinGecko, DefiLlama, Alchemy, and Etherscan APIs. No auth, no subscriptions.
Output
Returns block reward details including the miner address, block reward amount in ETH, uncle inclusion rewards, and details for each uncle block (uncle miner address, uncle position, uncle hash, and uncle reward). Mirrors the Etherscan block getblockreward API response structure.
Example use cases
Example prompt
“What were the block and uncle rewards for Ethereum mainnet block number 18000000? Use chain ID 1.”
Technical details
Endpoint
POSThttps://stablecrypto.dev/api/etherscan/block/getblockrewardWhen to prefer
Use this endpoint when you need to look up historical block mining or uncle rewards for a specific block number on an EVM-compatible chain. Prefer this over raw RPC calls when you want Etherscan-structured reward breakdowns including uncle details. Best for analytics, auditing miner payouts, or verifying block rewards on Ethereum, Polygon, Base, or other EVM chains.
Side effects
- Invalid block number returns an error or empty result
- Block number in the future returns no data
- Unsupported chain ID returns an error
- Malformed request body returns a 400-level error
- Upstream Etherscan API unavailability causes a 500-level error
