Base native or ERC-20 balance at the current head. GET /v1/base/balance/{addr} for ETH wei; add ?token=0x… for balanceOf at that token. Proof-stamped. No USD quote. Dead RPC is unread, not zero.

Base gas price, base fee and priority fee at head. Not an estimate of a specific call. Unread RPC is not zero.

Use when an agent needs to know what a Base address is at a known block: EOA, ERC-20, Uniswap V2/V3 pool, bare contract, or unread. Returns a typed object plus blockNumber and blockHash. A token that is not a pool is a token. Dead RPC is unreadability, not zeros.

Use when an agent needs to know whether a Base transaction landed. Returns pending, reverted, confirmed with confirmations, not_found, or unread. Decodes USDC Transfer logs. Proof-stamped with the head block. Missing value is null, not zero.

Base wallet snapshot at head: native ETH balance, nonce, is_contract. Optional ERC-20 balanceOf via ?token=. One 402, parallel RPC. No USD quote. Dead RPC is unread, not zero.

Compact a public HTTPS page into a token budget. LLM first; extractive fallback if the bus is down. A failed fetch is not an empty document.
