Publisher-provided text

• catalog FREE, no payment needed. Lists all 78 tools with a real example of the input and of the output each one returns, plus what a call costs and how to pay for it. C
• llm_completion LLM inference at a flat $0.005 per call, with no account, no API key and no token metering. POST a prompt, get the completion: the same price for 10 tokens or 4
• do Use when an agent has a job to get done and does not know which tool or in what order: describe it in plain words and it happens in ONE paid call: picks from 71
• evm_balance Use when an agent has to decide whether a wallet can pay before building a transaction: the native coin balance (ETH, MATIC...) of any address on Base, Ethereum
• evm_erc20_balance Use when an agent must confirm a wallet holds enough of a token before it swaps, pays or settles: the ERC-20 balance of any address for any token (USDC, USDT, D
• evm_token_info Use when an agent has a bare token address and must label or format it before showing or computing anything: name, symbol, decimals and total supply of any ERC-
• evm_token_price Use when an agent must put a number on a token before trading or reporting, and be able to defend it: spot price read straight from the deepest Uniswap V3 pool
• evm_gas Use when an agent is about to send a transaction and needs to know what it costs right now: the chain's current gas price in wei and gwei plus the cost of a pla
• evm_block Use when an agent has to decide whether what it just read on-chain is fresh, or whether a node is behind: the latest block height, its timestamp and how many se
• evm_tx Use when an agent has sent a transaction and must decide what to do next: the transaction by hash merged with its receipt in one call, so you get sender, recipi
• evm_nonce Use when an agent signs transactions one after another and must not collide with one already in flight: the confirmed nonce, the pending nonce (the one to use w
• evm_is_contract Use when an agent is about to send funds and must decide whether the destination is a plain wallet or a contract: returns isContract and the size of the deploye
• evm_chains Use when an agent has to pick a chain that is actually answering before it commits to one: every supported chain in a single call, each with its chain id, block
• evm_call Use when an agent needs a contract value that none of the typed routes covers: it runs any read-only call with your own calldata on five chains and returns the
• evm_receipt Use when an agent is waiting on a transaction and has to answer «did it work, and what did it cost»: the receipt by hash with success or revert, gas used, the f
• evm_estimate_gas Use when an agent is about to sign a transaction and must know whether it will fail and what it will cost: the gas this exact call needs, the current gas price,
• evm_can_i_send Use when an agent is about to sign a transaction and must decide whether it will go through right now: one call that answers canSend with the facts behind it -
• evm_gas_window Use when an agent can choose WHEN to send and must decide whether waiting would save anything: the fee paid across the last ~1000 blocks of this chain in one ca
• evm_storage Use when an agent must read something a contract does not expose with a getter and has to decide from it: a raw storage slot, returned as hex and as an integer.
• evm_erc20_allowance Use when an agent is about to approve a spender, or is auditing what it approved before: how much of a token the spender may still move on the owner's behalf, r
• evm_nft_owner Use when an agent must decide whether an NFT is still held by who it thinks: the current owner of an ERC-721 token id, with its tokenURI and the collection name
• evm_portfolio Use when an agent must see at once whether a wallet can cover something: the native balance plus the balance of every token you list, on one chain, in a single
• evm_fees Use when an agent is building an EIP-1559 transaction and must choose fee caps that will actually get it mined: the base fee plus suggested maxFeePerGas and max
• evm_ens Use when an agent has a name where it needs an address, or the other way round, before it can act: resolves an ENS name to its address or an address to its prim
• evm_token_safety Use when an agent must decide whether to touch a token at all: a pre-trade risk check on Base, Ethereum, Polygon, Arbitrum or Optimism, straight from the deploy
• evm_verdict Use when an agent needs one answer it can act on: a verdict on any ERC20 on five chains - a machine-readable label for who can act on your balance (no-owner-pow
• util_keccak256 Use when an agent is building something Ethereum will hash and must get the same digest the chain gets: Keccak-256 of any string or hex payload, with the byte c
• util_sha256 Use when an agent must prove two payloads are the same byte for byte, or sign an API request: SHA-256 of any string or hex payload, returned as hex and as base6
• util_address Use when an agent is handed an address and must decide whether it is safe to use before sending anything: it validates it and returns the EIP-55 mixed-case chec
• util_units Use when an agent must turn an on-chain integer into a human amount, or back, without losing money to rounding: converts between wei, gwei, ether and any token
