Schedule a recurring trigger: 5-field cron in UTC, at least 1 hour between runs, 100 runs included. On each run the gateway POSTs a signed cron.triggered webhook to your https callback_url; your agent then calls batch/execute or payroll/execute itself and pays for it as usual. Actions: batch.execute, payroll.execute, webhook.trigger.

Is this address a contract? On Ethereum, Base, Arc or BNB Chain: whether code is deployed, its size, the implementation behind an EIP-1967 or ZeppelinOS proxy, and an EIP-7702 delegation if the address is a wallet that delegates. Pass ?address=&chain=

x402engine — Resolve an ENS name to an Ethereum address

Read-only contract call (eth_call) on Ethereum, Base, Arc or BNB Chain: pass ?to=&data= (hex calldata) and optional &from=, get the returned bytes or the revert reason, at a named block. Nothing is signed or sent.

What an Arc wallet holds, with a USD value for each token: native USDC, EURC and APEX always, plus up to 20 more tokens you list in ?tokens=0x..,0x... Pass ?address=0x.... Balances are read live (Multicall3); each token is priced from its deepest Uniswap v4 USDC pool, and a token with no pool says so instead of showing $0. Returns per-token balance, price and value, and the wallet total in USD. A non-address or a failed read is refused before payment.

Currency exchange rate and conversion, read on chain from Chainlink FX feeds on Ethereum: pass ?from=EUR&to=JPY&amount=100. EUR, GBP, JPY, CHF, AUD, CAD, CNY, KRW, SGD, TRY, BRL, NZD, PHP, USD, plus gold (XAU) and silver (XAG). Cross rates come from two USD feeds, and each leg carries its feed address, round and age. A retired or unknown feed is refused before any charge.

Send guard for Arc: call it BEFORE sending USDC or a token. Pass ?from=<sending wallet>&to=<destination> (and &token=0x... for a token send). Returns verdict stop / check / ok with reasons: the destination is a lookalike of an address the sender really used (address poisoning), bait planted in the sender's history by a forged transfer, a token contract or the burn address, on the OFAC SDN list or USDC's own blacklist; the token is a fake USDC / EURC; or a brand-new address (check).

ERC20 allowance on Ethereum, Base, Arc or BNB Chain: how much a spender may move from an owner, raw and in token units, and whether the approval is effectively unlimited. Pass ?token=&owner=&spender=&chain=

Is this wallet on the OFAC sanctions list? Screens an address (EVM, Bitcoin, Tron, Solana) against the Treasury SDN list (about 1,060 digital currency addresses) and reads live USDC and USDT freeze status on chain. Sanctions check for a wallet address on any chain: is it on the OFAC SDN list (read from Treasury's official SDN.XML, about 1,060 digital currency addresses: Bitcoin, Tron, Ethereum, USDT, Solana and more), under which entry and programs, with the list's publication date.

Matches declared classification tokens against a supplied published dual-use control list. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age. This is neither legal advice nor customs advice.

Returns a single, verifiable snapshot of any EVM wallet: native balance, ERC-20 token balances, current block number, and recent activity count across the most popular chains (Ethereum, Base, Arbitrum, Polygon). Built for x402 agents that need on-chain facts without managing RPC keys or node infrastructure. Each call returns a deterministic JSON payload with a chain-specific block number at snapshot time so results can be independently verified against a public RPC or block explorer.
