`arb_block`	Fetch a block on Arbitrum One by decimal number, or the latest one when omitted: hash, timestamp, transaction count, gas used and limit, base fee in gwei and producer. Use for timestamps and confirmation counts; for current fees use arb_gas. A block that does not exist yet returns 404, uncharged. Side effects: none on any outside system (it only reads or computes), but each successful call costs $0.001 in USDC on Base or another supported network, paid with x402, or the same amount in prepaid card credits when the request carries an API key from /credits. That payment is why the tool is not marked read-only or idempotent: repeating a call charges again. Failed calls are never charged. Each caller gets 25 free successful calls first (over MCP they are used automatically).
`arb_gas`	Get current gas on Arbitrum One: gas price, base fee and suggested priority fee in gwei, plus what a plain ETH transfer (21,000 gas) costs right now. Takes no input. Use before sending a transaction or to decide whether to wait; for the fee a past transaction actually paid use arb_receipt. Side effects: none on any outside system (it only reads or computes), but each successful call costs $0.001 in USDC on Base or another supported network, paid with x402, or the same amount in prepaid card credits when the request carries an API key from /credits. That payment is why the tool is not marked read-only or idempotent: repeating a call charges again. Failed calls are never charged. Each caller gets 25 free successful calls first (over MCP they are used automatically).
`arb_is_contract`	Check whether a 0x address on Arbitrum One is a smart contract or a plain wallet: bytecode size, and whether it is an EIP-1167 minimal proxy and which implementation it points to. Use before sending funds or approving a spender; for a fuller risk verdict use check_counterparty. A malformed address is rejected with 400, uncharged. Side effects: none on any outside system (it only reads or computes), but each successful call costs $0.001 in USDC on Base or another supported network, paid with x402, or the same amount in prepaid card credits when the request carries an API key from /credits. That payment is why the tool is not marked read-only or idempotent: repeating a call charges again. Failed calls are never charged. Each caller gets 25 free successful calls first (over MCP they are used automatically).
`arb_logs`	List recent event logs a contract emitted on Arbitrum One over the last N blocks (1-1,000, default 50), optionally filtered by topic0 (the 0x 32-byte event signature hash). Returns up to 100 logs with block, transaction hash and topics. Use to watch transfers or contract events; for one transaction's outcome use arb_receipt. Side effects: none on any outside system (it only reads or computes), but each successful call costs $0.001 in USDC on Base or another supported network, paid with x402, or the same amount in prepaid card credits when the request carries an API key from /credits. That payment is why the tool is not marked read-only or idempotent: repeating a call charges again. Failed calls are never charged. Each caller gets 25 free successful calls first (over MCP they are used automatically).
`arb_nonce`	Read the transaction count (nonce) of a 0x address on Arbitrum One, both confirmed and including pending transactions. Use to build the next transaction or to tell whether an address has ever sent anything; for its balance use arb_balance. A malformed address is rejected with 400, uncharged. Side effects: none on any outside system (it only reads or computes), but each successful call costs $0.001 in USDC on Base or another supported network, paid with x402, or the same amount in prepaid card credits when the request carries an API key from /credits. That payment is why the tool is not marked read-only or idempotent: repeating a call charges again. Failed calls are never charged. Each caller gets 25 free successful calls first (over MCP they are used automatically).
`arb_receipt`	Get the receipt of a mined Arbitrum One transaction: success or reverted, gas used, effective gas price, fee paid in ETH, number of event logs and any contract created. Use to confirm a payment or call went through; for sender, value and calldata use arb_tx. Input is a 0x-prefixed 64-hex hash; a pending or unknown hash returns 404, uncharged. Side effects: none on any outside system (it only reads or computes), but each successful call costs $0.001 in USDC on Base or another supported network, paid with x402, or the same amount in prepaid card credits when the request carries an API key from /credits. That payment is why the tool is not marked read-only or idempotent: repeating a call charges again. Failed calls are never charged. Each caller gets 25 free successful calls first (over MCP they are used automatically).
`arb_token_balance`	Read one wallet's balance of one ERC-20 token on Arbitrum One: raw amount, decimals, symbol and the human-readable amount, live from the token contract. Use to check stablecoin or token holdings before a transfer or trade; for the native coin use arb_balance. Both inputs are 0x addresses (40 hex characters); no contract returns 404 and a non-ERC-20 contract 422, both uncharged. Side effects: none on any outside system (it only reads or computes), but each successful call costs $0.001 in USDC on Base or another supported network, paid with x402, or the same amount in prepaid card credits when the request carries an API key from /credits. That payment is why the tool is not marked read-only or idempotent: repeating a call charges again. Failed calls are never charged. Each caller gets 25 free successful calls first (over MCP they are used automatically).
`arb_token_info`	Look up the name, symbol, decimals and total supply of an ERC-20 token contract on Arbitrum One, live from the contract. Use to identify an unknown token address or to format raw amounts; for a holder's balance use arb_token_balance. Input is the token's 0x contract address; an address that is not an ERC-20 contract returns 422, uncharged. Side effects: none on any outside system (it only reads or computes), but each successful call costs $0.001 in USDC on Base or another supported network, paid with x402, or the same amount in prepaid card credits when the request carries an API key from /credits. That payment is why the tool is not marked read-only or idempotent: repeating a call charges again. Failed calls are never charged. Each caller gets 25 free successful calls first (over MCP they are used automatically).
`arb_tx`	Look up a Arbitrum One transaction by hash: sender, recipient, value in ETH, nonce, gas limit, the 4-byte function selector and its block. Use to see what was sent or whether it exists; for success or failure and fees paid use arb_receipt, for emitted events arb_logs. Input is a 0x-prefixed 64-hex hash; an unknown hash returns 404, uncharged. Side effects: none on any outside system (it only reads or computes), but each successful call costs $0.001 in USDC on Base or another supported network, paid with x402, or the same amount in prepaid card credits when the request carries an API key from /credits. That payment is why the tool is not marked read-only or idempotent: repeating a call charges again. Failed calls are never charged. Each caller gets 25 free successful calls first (over MCP they are used automatically).
`base64_decode`	Decode standard or URL-safe base64 to UTF-8 text. Missing padding is tolerated. Use to read encoded headers, tokens and data URLs.

`wallet`	Live snapshot of any address on Base: ETH balance, balances of major tokens (USDC, WETH, cbBTC, DAI, USDbC, cbETH, AERO, EURC) plus up to 20 extra token addresses you pass, the EVM account nonce, and whether the address is an EOA, a smart contract or an EIP-7702 delegated account. For EOAs the nonce reflects outgoing transactions only; this is not full transaction, token-transfer or trading history. Use to check a counterparty's holdings.
