Blockchain And Crypto x402 offerings

Crypto price / live coin quote: spot price, 24-hour change and 24-hour volume for Bitcoin, Ethereum, Solana or any Coinbase product (BTC-USD, ETH-USD, SOL-USD...), read at call time from Coinbase's public market data. Use it when an agent needs a current cryptocurrency price. Input: product_id such as BTC-USD. Bid/ask: market.ticker. Whole rate table: market.rates.

Exchange rates / currency conversion table: Coinbase's full rate table for one base currency against every crypto and fiat currency it quotes (USD to BTC, ETH, EUR, GBP, JPY...). Use it to convert amounts between currencies. Input: currency code such as USD.

Crypto ticker / bid and ask: live best bid, best ask, last price and volume for one Coinbase product from Coinbase's Exchange data host, an independent second source to market.quote. Input: product_id such as BTC-USD.

Base RPC endpoint, pay per call: any allowlisted read-only JSON-RPC method on Base mainnet (eth_call, eth_getBalance, eth_getLogs, eth_getBlockByNumber, eth_getTransactionReceipt and more) with your own params, no API key. Revert reasons come back as the result. Input: method; optional params.

Crypto market sentiment in one call: live Coinbase spot price, live Polymarket probabilities and recent news headlines (GDELT) on the same subject, analysed together in a written summary that says what the numbers do and do not support. Use it for a quick read on Bitcoin, Ethereum or any coin. Input: optional product_id (BTC-USD...), query, question, limit. Market data only, not investment advice.

Base network status and gas price: current block height and gas price (wei and gwei), live from a Base mainnet RPC node. Use it to check Base is moving, time an on-chain action or estimate gas before sending a transaction. Keyless, pay per call. No input needed.

Base transaction lookup by hash: sender, recipient, ETH value, block, success or failure, gas used and log count, with the receipt folded in, live from Base mainnet. Use it to confirm a payment or transfer landed on-chain. Input: hash (the 0x transaction hash). For the raw receipt use chain.rpc.

Base wallet lookup / address balance: ETH balance, transaction count (nonce) and whether the address is a smart contract or an ordinary wallet (EOA), live from Base mainnet in one call. Use it to check a counterparty, deposit address or contract before paying it. Input: address (0x...). For token balances or any other read use chain.rpc.

Forced-liquidation tape over a time window, reconstructed from the node-fills archive (Hyperliquid has no public liquidations feed). Each row is the liquidated user's fill as Hyperliquid's userFills WsFill, one per liquidated trade id, with the nested liquidation object {liquidatedUser, markPx, method market|backstop}. Priced per asset-hour ($0.005 base, $0.01 HIP-3/HIP-4) plus $0.05 per uncached archive hour pulled; up to 24 asset-hours/request, available ~2h after the hour closes.

The most-recent N OHLCV candles (≤5000), in Hyperliquid's candleSnapshot shape. Same per-row pricing as the windowed read ($0.00001 base for main/spot, $0.000025 premium for HIP-3/HIP-4); candles lag ~2 days.

Archive coverage for a coin's liquidations over a window (≤7 days): which archived hours hold liquidations and where the gaps are. Warms the cache for everyone after. Priced floor ($0.001) + $0.05 per archived hour examined.

Raw market trades over a time window: the live hot tier (~24h) plus S3 read-through for older history (archive from 2025-05-25), merged. Each row mirrors HL's WsTrade verbatim, including the buyer/seller addresses (`users`) and the trade `hash`. Rows come oldest-first (by time, then tid) for forward paging, unlike Hyperliquid's newest-first recentTrades. Priced per asset-hour ($0.015 base, $0.03 HIP-3/HIP-4) plus $0.05 per uncached archive hour pulled (warms the cache); ≤24 asset-hours/request.

The most-recent N open-interest / funding / ctx rows (≤5000), as {coin, ctx, time}. Priced per row ($0.000025 premium); served live (no lag).
