此 MCP 可以做什么

Provides live on-chain address, token, gas, and transaction status data across supported blockchain networks.

address_info

Balance, next nonce, and whether an address is a contract

Native balance, the next nonce to use, and whether the address holds contract code — the three things needed before sending from or to an address. Pass 'token' as well to read an ERC-20 balance for the same address in the same call. Values are read at the latest block, so a reorg can change them. Costs $0.008 USDC per call via x402 on Base.

输入模式

{'type': 'object', 'required': ['address'], 'properties': {'chain': {'type': 'string', 'examples': ['base'], 'description': 'ethereum, base, arbitrum, optimism or polygon. Defaults to base.'}, 'token': {'type': 'string', 'examples': ['0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913'], 'description': "Optional ERC-20 contract address to also report that token's balance."}, 'address': {'type': 'string', 'examples': ['0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045'], 'description': '0x-prefixed 20-byte address.'}}, 'additionalProperties': False}

demand_report

What agents are asking for most (free)

FREE, no payment. The aggregate of what agents have told us they are looking for, most-requested first, with the categories nothing available yet serves.

输入模式

{'type': 'object', 'properties': {'days': {'type': 'string', 'examples': ['30'], 'description': 'Window in days, default 30, max 90.'}}, 'additionalProperties': False}

gas_now

Current gas price on one or several chains

Live gas price on Ethereum, Base, Arbitrum, Optimism or Polygon — in wei and gwei, plus what a plain 21,000-gas transfer would cost in the native token, which is the number you actually budget with. Pass several chains comma-separated to compare where to execute. Call this immediately before sending a transaction: gas moves every block, so the answer is good for seconds, not minutes. Costs $0.005 USDC per call via x402 on Base.

输入模式

{'type': 'object', 'properties': {'chain': {'type': 'string', 'examples': ['base'], 'description': "One or more of ethereum, base, arbitrum, optimism, polygon — comma-separated, e.g. 'base,ethereum'. Defaults to base."}}, 'additionalProperties': False}

request_data

Tell us what data you are looking for (free)

FREE, no payment. Describe in your own words the data you are trying to buy — anything, not just on-chain data — and get back whether we operate a service that supplies it, with the MCP endpoint if so. Every request is catalogued so repeatedly-requested data gets built. Nothing identifying is stored, only the words of the request.

输入模式

{'type': 'object', 'required': ['need'], 'properties': {'need': {'type': 'string', 'examples': ['live electricity spot prices by ZIP'], 'description': 'What you are looking for.'}}, 'additionalProperties': False}

token_info

ERC-20 token details by contract address

Read an ERC-20's name, symbol, decimals and total supply straight from the contract on the chain you name, and confirm the address actually has code there. Use before quoting an amount or building a transfer: getting decimals wrong is the classic way to send 1,000,000x the intended value. An address with no code, or a contract that is not an ERC-20, is reported as such and is NOT charged. Costs $0.005 USDC per call via x402 on Base.

输入模式

{'type': 'object', 'required': ['address'], 'properties': {'chain': {'type': 'string', 'examples': ['base'], 'description': 'ethereum, base, arbitrum, optimism or polygon. Defaults to base.'}, 'address': {'type': 'string', 'examples': ['0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913'], 'description': '0x-prefixed 20-byte contract address.'}}, 'additionalProperties': False}

tx_status

Did this transaction succeed?

Status of a transaction by hash: success, failed or still pending, with the block it landed in, sender and recipient, value moved, gas used, the fee actually paid, and how many logs it emitted. Use to confirm an action you took really settled rather than assuming it did. An unknown hash is reported as not_found and is NOT charged. Costs $0.005 USDC per call via x402 on Base.

输入模式

{'type': 'object', 'required': ['hash'], 'properties': {'hash': {'type': 'string', 'examples': ['0x08001b920b214572ff2e7a4fc4560bafa717619b00b91561425ef6a325fdfedb'], 'description': '0x-prefixed 32-byte transaction hash.'}, 'chain': {'type': 'string', 'examples': ['base'], 'description': 'ethereum, base, arbitrum, optimism or polygon. Defaults to base.'}}, 'additionalProperties': False}
