Run before sending ETH or USDC or paying gas, to confirm the wallet really has enough. Never trust a balance remembered from earlier in a chat. Reads a wallet's ETH and native USDC balance on Base directly from the chain, at one block.

An executable swap on Base, routed by 0x across Uniswap, Aerodrome, Balancer, Curve and more. Returns the transaction for your own wallet to sign, plus the approval step if needed, minimum out, route and fees. We never hold funds. Name tokens as ETH, USDC, WETH, cbBTC, AERO… or a 0x address; buying an unknown token runs a sellability check first and refuses a honeypot unless force=1.

Api EndpointProvider: 402.com.tr

Use when: which token approvals on this Base wallet should I revoke? Check a Base wallet's ERC-20 approvals: allowances for 8 major tokens (USDC, WETH, USDbC, DAI...) to common spenders (Permit2, Uniswap Universal Router, Uniswap SwapRouter02, Aerodrome Router...); flags unlimited approvals.

Base token BATCH sell check: up to 10 token addresses in one call and one payment. For each token it simulates a small buy and an immediate sell inside eth_call (no trade is sent) and returns buy tax, sell tax, round-trip loss, flags and a plain summary; a token it cannot simulate is returned as not_simulated with the reason. Built for bots that screen many new tokens: $0.03 for up to 10 (single check: $0.005). Facts, not advice.

Base ERC-20 check before an agent buys or holds a token. Input: one contract address. Output: allow, warn, or block. Block: not a contract, not an ERC-20, zero supply, or the owner or token contract holds at least 50 percent. Warn: 20 to 50 percent held, proxy (EIP-1967, EIP-1167, or implementation()), or bytecode contains mint or pause. A selector does not prove the public can call it. Concentration covers only the owner and the token contract. Not an audit.

Api EndpointProvider: base-token-check.fly.dev

Base honeypot and tax check for trading agents: simulates a small buy and an immediate sell of the token on its deepest WETH pool (Uniswap v2/v3, Aerodrome) inside eth_call, and returns buy tax, sell tax, round-trip loss and whether the sell reverted. $0.005. Simulation at one block, not a guarantee.

Api EndpointProvider: base-facts.yankii.fr

Base ERC-20 verdict of a token contract address. Returns: an AI-written token verdict on one token contract: grade (BASED/MID/COOKED/RADIOACTIVE, a stated rule over the contract's own state), a one-liner and a roast, and the facts read: code size, name, symbol, decimals, supply, owner(), proxy slots. It does not read holders, liquidity or price and makes no safety or legitimacy call.

Api EndpointProvider: ari001.tailb4ac3a.ts.net

Base token verdict for trading agents: risk level, score and flags (proxy, mint, pause, blacklist, owner, DEX liquidity on Uniswap v2/v3 and Aerodrome), each with the on-chain fact behind it. Facts and heuristics, not financial advice.
