Tools as reported by the server

• mach_choose
  Free decision layer: map an agent goal to the narrowest paid MACH Base capability, exact price, expected result fields and exact next request. Returns no live chain data and has no side effects.
• base_block_number
  Check Base chain progress: return the latest mainnet block number for freshness checks and polling. This is not transaction confirmation. Costs $0.005 USDC via x402.
• base_gas_price
  Check the current Base gas price in wei before estimating transaction fees. The quote alone is not the total transaction cost. Costs $0.005 USDC via x402.
• base_wallet_balance
  Check whether a Base wallet has native ETH available for gas: return its balance in wei. Read-only; no wallet access or signing. Costs $0.005 USDC via x402.
• base_erc20_balance
  Check a wallet’s USDC or ERC-20 balance on Base: return raw token units for a specified token contract and wallet address. Costs $0.005 USDC via x402.
• base_nonce
  Prepare a Base transaction: get a wallet’s current nonce without signing or broadcasting a transaction. Costs $0.005 USDC via x402.
• base_contract_code
  Tell a Base contract address from an externally owned account: return whether code is deployed and its bytecode size. Not a security audit. Costs $0.005 USDC via x402.
• base_allowance
  Check a Base token approval before an agent acts: return the ERC-20 allowance for one token, owner and spender. Does not grant approval. Costs $0.005 USDC via x402.
• base_receipt
  Check whether a Base transaction was mined and succeeded: return receipt status and confirmations. This does not prove the correct payee, token amount or service delivery. Costs $0.005 USDC via x402.
• base_logs
  Find Base smart-contract events in a bounded block range: return onchain logs filtered by contract address and optional topics. Costs $0.005 USDC via x402.
• base_eth_call
  Read Base contract state without broadcasting a transaction: run eth_call with supplied calldata and return the raw response. Costs $0.005 USDC via x402.
• base_transaction
  Inspect a Base transaction by hash: retrieve sender, recipient, value, calldata and transaction fields. Use Transaction Context for receipt and confirmation status. Costs $0.008 USDC via x402.
• base_block
  Inspect a Base block by number or tag: retrieve its header and transaction hashes to investigate chain activity. Costs $0.005 USDC via x402.
• base_transaction_context
  Investigate a Base payment timeout or failed transaction with transaction, receipt, gas and fee context. Onchain success is not proof that a specific USDC obligation or service delivery was met. Costs $0.008 USDC via x402.
• base_wallet_snapshot
  Check a Base wallet’s funding context in one read: return native ETH and balances for up to ten specified ERC-20 contracts. No signing or custody. Costs $0.005 USDC via x402.
• base_total_supply
  Check a Base ERC-20 or ERC-721 contract’s reported total supply. Contract data is not independently audited circulation. Costs $0.005 USDC via x402.
• base_contract_info
  Identify a Base contract before interacting: inspect bytecode size, available token metadata and common interface signals. Not a security audit. Costs $0.005 USDC via x402.
• base_erc20_transfers
  Find recent ERC-20 Transfer events on Base, optionally filtered by sender or recipient wallet. Results cover only the queried block window. Costs $0.005 USDC via x402.
