Gas price
Gas price: live gas fees for Ethereum, Base, Arbitrum, Polygon and Solana in one call. Use before sending a transaction to pick a fee or the cheapest chain. Returns base fee, slow/standard/fast priority fees, max fee, congestion, and the USD cost of a transfer, an ERC-20 transfer and a swap per chain, plus Solana priority fees. Optional chain. 0.002 USDC/call; failed calls are free.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
