• arb_balance≈ 250 tokens

  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 $0.003/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_block≈ 228 tokens

  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.

• polygon_is_contract≈ 251 tokens

  Check whether a 0x address on Polygon PoS 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=0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Price $0.003/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.

• polygon_logs≈ 324 tokens

  Recent contract event logs on Polygon PoS (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 polygon_receipt. Example: address=0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Price $0.003/call via x402 USDC or a card key (/credits), first 25 free; failed calls free.

• polygon_nonce≈ 240 tokens

  Read the transaction count (nonce) of a 0x address on Polygon PoS, 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 polygon_balance. A malformed address is rejected with 400, uncharged. Example: address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045. Price $0.003/call via x402 USDC or a card key (/credits), first 25 free; failed calls free.

• polygon_receipt≈ 273 tokens

  Transaction receipt on Polygon PoS (eth_getTransactionReceipt): success or reverted, gas used, effective gas price, fee paid in POL, number of event logs and any contract created. Use to confirm a payment or call went through; for sender, value and calldata use polygon_tx. Input is a 0x-prefixed 64-hex hash; a pending or unknown hash returns 404, uncharged. Example: hash=0x23e86c30c46638b2e9798692fe89327a66aa8569a5d4a566125f655aeb8f80c7. Price $0.003/call via x402 USDC or a card key (/credits), first 25 free; failed calls free.

• polygon_token_balance≈ 295 tokens

  ERC-20 token balance of a wallet on Polygon PoS (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 polygon_balance. Both inputs are 0x addresses (40 hex characters); no contract returns 404 and a non-ERC-20 contract 422, both uncharged. Price $0.003/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.

• polygon_token_info≈ 276 tokens

  Look up the name, symbol, decimals and total supply of an ERC-20 token contract on Polygon PoS, live from the contract. Use to identify an unknown token address or to format raw amounts; for a holder's balance use polygon_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=0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359.

• polygon_token_transfers≈ 358 tokens

  List a wallet's recent transfers of one ERC-20 token (default USDC) on Polygon PoS, 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 polygon_token_balance. Malformed addresses are rejected with 400, uncharged. Example: address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045. Price $0.003/call via x402 USDC or a card key (/credits), first 25 free; failed calls free.

• polygon_tx≈ 266 tokens

  Look up a Polygon PoS transaction by hash: sender, recipient, value in POL, 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 polygon_receipt, for emitted events polygon_logs. Input is a 0x-prefixed 64-hex hash; an unknown hash returns 404, uncharged. Example: hash=0x23e86c30c46638b2e9798692fe89327a66aa8569a5d4a566125f655aeb8f80c7.

• wallet≈ 315 tokens

  Base only (all 5 chains: wallet_balances; USD values: wallet_portfolio). An address on Base: ETH and major token balances (USDC, WETH, cbBTC, DAI, USDbC, cbETH, AERO, EURC) plus up to 20 token addresses you pass, the account nonce, and whether it is an EOA, a contract or an EIP-7702 account. The nonce counts outgoing transactions only; not transfer or trading history. Use to check a counterparty's holdings. Example: address=0x4200000000000000000000000000000000000006. Price $0.005/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.

• wallet_balances≈ 286 tokens

  Read a wallet's native coin and USDC balances on Base, Ethereum, Arbitrum, Optimism and Polygon in one call, live from each network, plus the USDC total. Use to find where a wallet's funds are before a payment or bridge; for one token on one network use <chain>_token_balance, for all tokens on Base use wallet_portfolio. A network whose nodes do not answer is listed with an error instead of failing the call. Example: address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045.
