LIVE ENDPOINT METADATA

Single-fact: what does Ethereum mainnet gas cost RIGHT NOW? Returns the latest block’s base fee + blob base fee AND the consensus-computed next-block projection (not a guess — the protocol’s own EIP-1559/4844 arithmetic), straight from eth_feeHistory. Fields: {block, base_fee_gwei, blob_base_fee_gwei, gas_used_ratio, next_base_fee_gwei, next_blob_base_fee_gwei}.

METADATA PROVENANCE

Source catalog records are retained separately from live endpoint observations. Sonar score, uptime, and latency are advisory metrics. CDP indexing is not inferred from validation.
