Latest observed weather signal for one city — a single-signal SPOT snapshot (like a market-data quote). Flat $0.01, payable by a STOCK x402 client (no binding nonce). Never returns history or more than one signal. Uncharged on unknown-city / no-data-yet.

Request a real USDC loan for an AI agent on Base mainnet from RSoft Bank: a real lender, not a calculator. Call it when your agent needs capital. The agent signs an EIP-712 LoanRequest (wallet, amount, nonce, deadline); the bank underwrites it and disburses USDC on-chain to the agent wallet. No sponsor: 2 USDC flat; with one: from 5 USDC, growing per repaid loan. Free pre-check first: GET /api/pre

Use this to check a draw independently: recomputes the SHA-256 of a revealed server_seed against its hash, and the numbers of a swoge-hmac-sha256-v1 draw, or the 52-card shoe of a SWOGE casino hand (scheme swoge-casino-shoe with its nonce). Price: $0.003 in USDC on Base or Solana, or $0.02 in USDG or $SWOGE on Robinhood Chain (tool price + settlement cost, minimum $0.02).

Check whether a Base transaction settled x402 payments (USDC transferWithAuthorization, EIP-3009): for each, the payer, the payTo address, the amount in USDC, the authorization nonce, the facilitator that sent it, and the seller behind the payTo address from Bazaar listings (origins and 30-day payers).

Payment security firewall scan for an OUTGOING x402 payment: PII/secret leak detection in payment metadata, nonce replay detection, overpayment detection, prompt-injection-triggered payment analysis (fast + deep tiers), canonical-USDC asset verification, merchant pinning, velocity/spend caps, and counterparty reputation cross-check. Returns allow/flag/block with per-check reasons and an Ed25519-si

Base wallet lookup / address research API: ETH + USDC balance with USD value (CoinGecko/Coinbase quotes), EOA or smart contract, nonce (tx count), gas base fee, ERC-20 token holdings and recent USDC inflows/outflows with counterparty count for any Base mainnet address. Wallet analytics, portfolio and onchain due diligence for agents. Live public RPC reads at request time; pay per call with x402 US

Pay-per-call cited research brief. The request carries a query and 1 to 12 quotes with source URLs; the response is a short brief that cites only those quotes, at 0.008 USDC per call on Base. Payment settles after the brief is produced. A client nonce header makes a retry free of a second charge.
