1gateway — Base wallet balances: ETH + many ERC-20s in one call, with nonce and contract flag
https://1gateway.dev/v1/onchain/base/balancesOverview
Use when an agent needs what a Base address holds in one call instead of one RPC call per token. Input: address; optional tokens (up to 20 ERC-20 addresses, comma-separated; default USDC, EURC, USDbC, WETH, cbBTC, cbETH, wstETH). Output: JSON block+time, ETH balance, per-token symbol, decimals, raw and decimal balance, nonce, isContract. Chain state only, no prices. Bad input: 400, not charged. Example: ?address=0x6246eee0355Dd7A93C888fE59e1151388A0cC5a1 Pay per call with USDC on Base via x402 (no signup, no API key); failed calls are never charged. Docs: https://1gateway.dev/agents.md
