Aggregated market snapshot: Ethereum mainnet gas price (Gwei), ETH/USD spot price, and the latest Base mainnet block number and timestamp — combined into one call. Optional ?ref=<address> pays that wallet a 20% referral cut, sent as a separate on-chain transfer after settlement.
Returns composite cashew data via a paid API endpoint.
Read recent large ERC-20 transfers directly from Base, Ethereum, or Arbitrum by scanning Transfer logs over the most recent blocks and filtering by a minimum token amount. Defaults to USDC on Base. Public RPC providers cap the scan window, so this covers the most recent blocks rather than a long history, and it does not label exchange wallets.
Send a payment via Venmo or PayPal. Requires KYC verification on the calling wallet; if not yet verified the response returns a kyc_url instead of sending the payout. The on-chain x402 payment credits the user's account balance via the standard deposit webhook, so abandoned/unverified flows can be recovered with POST /withdraw.
Load a reloadable card balance with USDC. Pay from either chain: the card issuer only accepts USDC on Base, and Laso bridges the payment to the account holder's own deposit address at the issuer over CCTP, which mints native USDC so the full amount arrives. Laso absorbs the bridge cost, so the price is exactly the amount that lands on the balance. Requires a linked card issuer account. Follow with POST /create-reloadable-card to create a card against the balance.
Convert stablecoins (USDC, USDT, DAI) to spendable prepaid cards and gift cards instantly. Works with Google Pay. Multi-chain: Ethereum, Solana, Stellar, Arbitrum, Base, Polygon.
Send dollars to a bank account by ACH. Requires a bank destination registered beforehand with addBankingDestination (list them at GET /bank-recipients), which in turn requires an approved banking profile. The on-chain x402 payment credits the user's account balance via the standard deposit webhook, so a payout that cannot be fulfilled leaves nothing stranded — retry, or recover the funds with POST /withdraw.
Order an international non-reloadable prepaid card (USD). The order is queued and fulfilled by an admin, after which the card details are retrievable via GET /get-card-data with card_type="Non-Reloadable International". A 3.8% fee is added on top of the on-card amount, or less while a fee promotion is running; the 402 challenge carries the exact total. Submit a whole dollar on-card amount.
LastLook Data — Most recent value for any supported FRED series. Use ?id=IORB, ?id=EFFR, ?id=MORTGAGE30US, ?id=FEDFUNDS, ?id=DGS10, etc.
The current chain tip (latest block height) via eth_blockNumber, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. The freshness read settlement, indexing and trading agents poll to know where the chain is. Live public RPC; one paid call. List your own x402 service on bazaar.agentexchange.work/listings: 1 USD, 30 days, live at once, no account.
The latest block number on Ethereum, Base, Polygon, Arbitrum or Optimism from keyless public nodes with fallback. Use it as the cheapest possible on-chain read: a liveness check for a chain, a timestamp anchor for a query, or the first paid call to prove an x402 client works end to end.
Returns the latest market price for a requested asset or symbol.
Reads a token's EARLIEST transfers to judge how it was launched: many recipients in a single early block or a tight block span is a sniped/bundled launch (coordinated, expect correlated dumping); very few early holders is dangerous concentration; a spread is organic. Returns the first holders and a verdict. The launch-quality read that pairs with b20-launch-radar — a heuristic, not proof. Pass first= (default 40). Not financial advice.
