blockchain-gas-price-data

Convert wei integer strings into gwei for readable gas quotes. Call when you need human-readable gas price from a wei field without an RPC call. Returns gwei float plus original wei string as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Compute total gas cost in ether from used gas and price wei. Call when budgeting ETH spend for a planned or observed transaction. Returns gas cost in eth as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Estimate gas cost in USD given used gas, price, and ETH/USD. Call when operator reports that need approximate dollar gas spend. Returns usd cost estimate (caller supplies eth price) as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Compute gas_used × gas_price as total gas cost in wei. Call when estimating tx cost from known used gas and price without a node. Returns gas cost wei string as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

SYNTHORA gas-oracle-multi: gas price across 5 chains (ethereum, base, arbitrum, optimism, polygon), each VERIFIED by two independent public RPCs with divergence report — a single RPC can lie or lag; dual-verified is what you time transactions with. Free public RPCs, no key. $0.005 USDC x402 Base.

Current gas price + base fee for a chain, with an ERC20-transfer cost estimate.

Latest fossil fuel energy as a share of total energy consumption across every country. Returns JSON.

Current Great Britain electricity generation mix by fuel percentage (no params). Returns JSON.

Latest gross national income per capita in current US dollars across every country. Returns JSON.

Latest GDP deflator inflation rate across every country. Returns JSON.

Live gas price (gwei) on Ethereum and Base — transaction-cost signal for onchain agents. Live. Returns JSON.

Latest gross national income per capita at purchasing power parity across every country. Returns JSON.

Ethereum mainnet gas prices (safe / standard / fast tier) real-time from Etherscan V2. AI agent MEV bot, trading bot, dApp tx-timing API, ETH gas oracle, pay-per-call. Time transactions for cost efficiency.

Base gas price check: the current gas price and latest block number; add ?gasLimit=150000 to also get what a transaction that size costs in ETH and USD

Convert gas prices from gwei into wei integer strings for EVM transactions. Call when you hold gas price in gwei and need wei for eth_gasPrice-style fields or tx builders. Returns wei as a decimal integer string plus input gwei as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Base network gas price and latest block, optionally costed for a transaction size

Takes what the caller holds and what the seller accepts and works out which combinations can settle the amount. All costs are brought into USD, otherwise no comparison is possible: gas on the source chain plus, where needed, the cost of a swap or a bridge. Routes that require a swap or a bridge are marked explicitly - they often look cheaper on paper and are slower and riskier in practice. Every assumption is named in assumptions; nothing is folded in silently. Limits: gas costs are ORDERS OF MA

Live gas prices across BNB Chain, Polygon, Arbitrum, Base, Avalanche and Optimism, converted to USD and sorted cheapest-first. Returns gas price in gwei, base fee, and the actual USD cost of a transfer, an ERC-20 transfer and a swap on each chain. Gwei is NOT comparable across chains because the gas token differs in price; pricing in USD is the only ranking that answers where a transaction really costs least. For bridging, routing and execution-timing agents.

Current block number and gas price for Base and Polygon mainnet, fetched live via RPC on every call. Unlike this catalogue's corpus-search listings, this makes a real outbound network call on purchase -- freshness is the product, not a stored snapshot.

eth_estimateGas for a bounded call on Base for $0.001 USDC (max 4KB data).

Live gas price (wei and gwei) for Base or Ethereum mainnet from public RPC.

Base gas price / base fee / priority fee snapshot for $0.001 USDC via live JSON-RPC.

Read the current eth_gasPrice value from a supported public Base, Ethereum, or Arbitrum JSON-RPC endpoint.
