btc_priceread-only | 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. Use to convert between sats and fiat, to value a Bitcoin or Lightning payment, or to check the BTC price before a trade. 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. |
contract_riskread-only | Limited Base contract bytecode, EIP-1967 slot and zero-supply heuristics. Missing or unsupported property reads are null; RPC transport failures return 502. Ownership renunciation requires a confirmed zero owner. Empty slots do not identify uninitialized proxies. EOAs return not-applicable. Not a full security audit; see endpoint details for coverage limits. Use before approving 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. Reads or computes only and changes nothing; each call is charged, so repeats are not free. |
fxread-only | 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, to=EUR,GBP,SEK, amount=100. 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. |
liquidity_pool_auditread-only | Base DEX pair lookup through DexScreener: verified pair identity, tokens, reported liquidity, volume, trades and pair age where available. Returns source and retrieval time; missing fields are null. No pool-security or investment-risk assessment. Missing pairs return 404; upstream failure returns 502. Example values are illustrative. Use to check a pair's liquidity before trading. Example: address=0x98c7A2338336d2d354663246F64676009c7bDa97. Price $0.03/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. |
mev_simulatorread-only | 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. |
price_tokenread-only | USD price of any ERC-20 token on Base, Ethereum, Arbitrum or Optimism, computed from the deepest Uniswap v3 pool against USDC or WETH, read live from the chain. Returns the pool, its fee tier, the quote-token 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: address=0xcbB7C0000aB88B473b1f5aFd9ef808440eed33Bf, chain=base. 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. |
price_tokensread-only | USD prices for up to 20 ERC-20 tokens on Base, Ethereum, Arbitrum or Optimism in one call, each from its deepest Uniswap v3 pool against USDC or WETH, read live from the chain, with pool, reserve and a thin-liquidity flag. Tokens without a pool are listed under unpriced instead of failing the call. Spot prices, not time averages. Use to value a basket of tokens or refresh a watchlist in one paid call. Price $0.005/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. |
tokenread-only | Live on-chain facts for any ERC-20 token on Base: name, symbol, decimals, total supply, owner address and whether ownership is renounced, paused state, proxy detection (EIP-1967 and minimal proxy) with implementation and admin addresses, 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. Price $0.01/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. |
token_reportread-only | Base token heuristic screening plus DexScreener market data, source and retrieval time. Returns owner, paused and proxy facts with limited selector checks. A mint selector does not prove callable minting; missing or unavailable evidence remains unknown. Illustrative examples are not live quotes. Not a safety guarantee; see endpoint details for coverage limits. Use before swapping into an unfamiliar Base token. Example: address=0x4200000000000000000000000000000000000006. Price $0.02/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. |
trade_insightread-only | 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. Price $0.05/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. |
wallet_auditread-only | Returns a heuristic high/medium/low address risk tier, named flags, ETH balance, holdings of 4 major tokens (USDC, WETH, cbBTC, DAI), and the Base EVM account nonce. Per-token risk is unknown because token contracts are not audited here. For EOAs the nonce counts outgoing transactions only, not full history. Address type is reported separately and does not affect the balance/nonce-based risk tier. Use to screen an address before paying it. Example: address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045. Price $0.02/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. |
wallet_portfolioread-only | USD value of a wallet on Base, Ethereum, Arbitrum or Optimism: native ETH plus major tokens (USDC and WETH everywhere, the common Base tokens on Base) and up to 20 tokens you add, each priced from its deepest Uniswap v3 pool, read live from the chain. 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. Price $0.005/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. |
