Schema Quality & AI Usability70
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 12604 tokens (~196/item across 64 items; 64 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
  • Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (2% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 64 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 65 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
arb_balance ~178

Native ETH balance (eth_getBalance) of any 0x wallet address on Arbitrum One at the latest block, in wei and in ETH. Use to check whether a wallet can pay gas or a transfer; for ERC-20 tokens use arb_token_balance, for all holdings at once use wallet_portfolio. A malformed address is rejected with 400, uncharged. Example: address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

NameTypeReqDescription
addressstringyes0x wallet or contract address

No output schema declared.

No examples provided.

arb_block ~145

Latest block number and block details on Arbitrum One, or any block by decimal number: 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. Example: number=latest. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

NameTypeReqDescription
numberstring–Block number, or 'latest' (default)

No output schema declared.

No examples provided.

arb_gas ~171

Current gas price on Arbitrum One (eth_gasPrice): 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. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

NameTypeReqDescription
onlystring–Optional: comma-separated top-level result keys to keep, for a smaller answer (for example only=price,symbol); unknown keys are ignored and an empty match returns the full result

No output schema declared.

No examples provided.

arb_is_contract ~172

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. Example: address=0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

NameTypeReqDescription

arb_logs ~221

Recent contract event logs on Arbitrum One (eth_getLogs): the events a contract emitted 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. Example: address=0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free.

arb_nonce ~161

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. Example: address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

NameTypeReqDescription

arb_receipt ~199

Transaction receipt on Arbitrum One (eth_getTransactionReceipt): 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. Example: hash=0xf03682db039f7b1b72ddf4d17572738f142cf63ecb36c90afa570430ea9774c4. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

NameTypeReqDescription

No output schema declared.

No examples provided.

arb_token_balance ~205

ERC-20 token balance of a wallet on Arbitrum One (USDC, USDT, WETH or any token, via balanceOf): 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. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

NameTypeReqDescription

tokenstringyesToken: a ticker such as USDC, USDT, WETH or DAI, or the 0x ERC-20 contract address

No output schema declared.

No examples provided.

arb_token_info ~205

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 a ticker (USDC, WETH…) or the token's 0x contract address; an address that is not an ERC-20 contract returns 422, uncharged. Example: token=0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

arb_token_transfers ~272

List a wallet's recent transfers of one ERC-20 token (default USDC) on Arbitrum One, in and out, over the last N blocks (1-2,000, default 1,000): direction, counterparty, amount and transaction, newest first, up to 50. Use to confirm a payment arrived or see what was sent; for the current balance use arb_token_balance. Malformed addresses are rejected with 400, uncharged. Example: address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free.

Use to confirm a payment or call went through; for sender, value and calldata use op_tx. Input is a 0x-prefixed 64-hex hash; a pending or unknown hash returns 404, uncharged. Example: hash=0x721f3e9a996da49e2a8929bd2dd42e0f51344c11d7ca7bc3328fda349cdfae89. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

op_token_balance ~203

ERC-20 token balance of a wallet on Optimism (USDC, USDT, WETH or any token, via balanceOf): 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 op_balance. Both inputs are 0x addresses (40 hex characters); no contract returns 404 and a non-ERC-20 contract 422, both uncharged. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

op_token_info ~204

Look up the name, symbol, decimals and total supply of an ERC-20 token contract on Optimism, live from the contract. Use to identify an unknown token address or to format raw amounts; for a holder's balance use op_token_balance. Input is a ticker (USDC, WETH…) or the token's 0x contract address; an address that is not an ERC-20 contract returns 422, uncharged. Example: token=0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

op_token_transfers ~268

List a wallet's recent transfers of one ERC-20 token (default USDC) on Optimism, in and out, over the last N blocks (1-2,000, default 1,000): direction, counterparty, amount and transaction, newest first, up to 50. Use to confirm a payment arrived or see what was sent; for the current balance use op_token_balance. Malformed addresses are rejected with 400, uncharged. Example: address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.
