    Description, as the server wrote it
    Foreign exchange rates from the European Central Bank for about 30 major currencies (USD, EUR, GBP, JPY, CHF, SEK, CAD, AUD, CNY, INR, BRL and more). Give a base currency, optionally the target currencies and an amount, and get the rates, the converted amounts and the date the rates apply to. Use for currency conversion, invoice and price calculations, and reporting in another currency. Example: from=USD. 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.

    Current Bitcoin (BTC) spot price in USD, EUR, GBP, CAD, CHF, AUD and JPY, averaged across major exchanges, with the number of satoshis per US dollar and the time of the price.

      What this check looks for
    Description, as the server wrote it
    Check a Base contract before you approve or call it: a low to critical risk tier with named flags (proxy, proxy with no implementation, tiny bytecode, zero token supply), plus bytecode size, the EIP-1967 implementation slot and ERC-20 owner, renounced and paused reads. Unreadable reads are null; EOAs return not-applicable. Limited heuristics, not a full security audit. Use before approving a spender or calling an unfamiliar Base contract. Example: address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. Price $0.02/call via x402 USDC or a card key (/credits), first 25 free; failed calls free.

    Description, as the server wrote it
    Live Hyperliquid perpetual futures data for a coin (BTC, ETH, SOL, HYPE…): mark, oracle and mid price, hourly funding rate and its APR, premium, open interest in coins and USD, 24-hour volume and price change, and max leverage. Without a coin, the 20 most traded markets by 24-hour volume. Read from Hyperliquid's public API. Use for funding-rate checks, basis trades, derivatives dashboards and market context.

      What this check looks for
    Description, as the server wrote it
    Check a Base DEX pool before you trade or add liquidity: give a pair address and get the verified DEX, both tokens, reported liquidity, 24h volume and trades, and pair age from DexScreener, with source and retrieval time. Missing fields are null; an unknown pair returns 404. Market data only, no pool-security or investment-risk assessment. Use to confirm a pair is real and deep enough before trading; token red flags: token_report. Example: address=0x98c7A2338336d2d354663246F64676009c7bDa97.

    Description, as the server wrote it
    Estimates Base gas costs from current fees and priority-fee presets. Fixed gas units (100k simple, 250k complex, 180k liquidity) are typical assumptions, not transaction-specific estimates or quotes. Valid values: standard, high-mev (3x priority fee), low-gas (half); invalid values return HTTP 400 without charge. No transaction simulation, mempool observation, or MEV/sandwich-risk measurement. Use to budget gas for a Base transaction. Example: scenario=standard. Price $0.04/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.

    Description, as the server wrote it
    Crypto token USD price by ticker (ETH, BTC, USDC, AERO, ARB, OP, LINK…) or by any ERC-20 0x address on Base, Ethereum, Arbitrum or Optimism, from the deepest Uniswap v3 pool against USDC or WETH, read live from the chain. Returns the pool, its fee tier, the quote reserve and a thin-liquidity flag. Spot price, not a time average. No pool returns 404, uncharged. Use to value a token or check a quote before a swap or payment. Example: symbol=ETH. Price $0.003/call via x402 USDC or a card key (/credits), first 25 free; failed calls free.

Tokens without a pool are listed under unpriced instead of failing the call. Spot prices. Use to value a basket of tokens or refresh a watchlist in one paid call. Example: symbols=ETH,BTC,AERO.

    Base only (other chains: <chain>_token_info). Live on-chain facts for an ERC-20 token on Base: name, symbol, decimals, total supply, owner and whether ownership is renounced, paused state, proxy detection (EIP-1967, minimal proxy) with implementation and admin, and bytecode heuristics for mint, pause, blacklist and fee-setter functions. Use for token due diligence and rug-pull or honeypot screening before a swap. Example: address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.

    Description, as the server wrote it
    Check a Base token before you swap into it: a high/medium/low risk verdict with named red flags (paused transfers, blacklist, owner-set fees or tax, a mint selector with a live owner, upgradeable proxy, no or thin liquidity, a pair under 7 days old, buys but no sells as a honeypot sign) plus live DexScreener price, liquidity, volume and FDV. Heuristic screening, not a safety guarantee. Use before swapping into an unfamiliar Base token. Example: address=0x4200000000000000000000000000000000000006.

    Description, as the server wrote it
    Combines the Base token-report risk tier and flags, available DEX market data, and wallet-audit risk tier, flags, account nonce, and native balance. Returns the underlying indicators separately; it does not generate buy/sell recommendations or calibrated confidence, and does not evaluate holder concentration. The account nonce is not full transaction, token-transfer, or trading history. Use as one input before a Base trade.

Address type is reported separately and does not affect the tier; token contracts are not audited. Use to screen a Base address; OFAC and other chains: check_counterparty.

Returns holdings, total and anything that could not be priced. Not a full token inventory. Use to check what a wallet is worth before trading, lending or paying.
