01Tools · 24
How to read this: tool names here are observed from a live tools/list handshake. The Risk label is a heuristic inferred from the tool name (write/destructive verbs), not from executing the tool — a conservative guess, not a verified capability. We never escalate risk from a description. Found one that's wrong? Tell us — we fix on report.
| Tool | Risk | Side effects | Approval |
|---|---|---|---|
| bridge_prepare_payment Returns the exact x402 payment request for a bridge (network, asset, payTo contract, amount, EIP-712 domain) and the URL to call. Pay it with your own x402 client: sign one EIP-3009 authorization and repeat the GET with the PAYMENT-SIGNATURE header. You receive exactly `amount` at your own address on the destination. This tool does not pay or sign anything. | read | false | unknown |
| bridge_quote Free. Exact price to move USDC between Base and Arc with the Liquid Bridge: what you pay, what you receive (exactly `amount`), the fee breakdown and the ETA. No payment, no wallet needed. | unknown | unknown | unknown |
| bridge_referral_earnings Free. Unclaimed Liquid Bridge referral earnings for an address on each chain, and how they are paid out. Earn by adding ref=<your address> to bridge calls: 20% of Liquid's fee. | unknown | unknown | unknown |
| bridge_routes Free. Every Liquid Bridge route with its live price for 1 USDC and whether it is open. | unknown | unknown | unknown |
| bridge_status Free. Circle attestation and mint state for a bridge, by its burn transaction hash (returned by the bridge call). | read | false | unknown |
| cctp_status Free. Status of ANY Circle CCTP v2 USDC transfer (not only Liquid's) by its burn transaction hash: attestation, whether it was minted on the destination, and exactly how to finish a stuck one (receiveMessage with the message and attestation). Chains: Ethereum, Avalanche, OP Mainnet, Arbitrum, Base, Polygon PoS, Unichain, Linea, Sonic, World Chain, Arc. | read | false | unknown |
| gas_sponsor_info Free. How to send a transaction on Base, Polygon or Solana with a wallet that holds USDC but no ETH/POL/SOL: the x402-paid gas sponsor, its price rule (from $0.03) and lanes. | read | false | unknown |
| liquid_guide Free. Overview of every Liquid Agent service for agents (bridge, stocks, signals, gas sponsor), prices and where the full docs are. | unknown | unknown | unknown |
| payment_readiness Free. One call to know if a wallet can pay an x402 endpoint right now: reads the endpoint's 402, checks the wallet's balance on each accepted network, and if it cannot pay, returns the cheapest fix (e.g. move USDC from the chain where it sits, with the exact bridge_quote arguments). | read | false | unknown |
| polymarket_prepare Returns the x402 payment request for Polymarket crypto Up/Down data (BTC, ETH, SOL, XRP; 5m and 15m; $0.002 USDC on Base or Polygon): the OFFICIAL price to beat for the live 5m or 15m window (matched to the cent against Polymarket's results), the live Chainlink price and its distance from the price to beat, seconds left, token ids and market prices. Pass start (unix) for a past window's official outcome. Pay it with your own x402 client. This tool does not pay. | read | false | unknown |
| stocks_basket Free. The on-chain tokenized US stock index on Base (NVDA, META, AAPL, GOOGL): live prices, fees, how to buy from $1. | unknown | unknown | unknown |
| stocks_buy Free. Invest USDC into your vault from $1 (USDC 6 decimals: "1000000" = $1). Easiest: set usePermit=true with owner, sign the returned typedData off-chain (free), then call again with permitDeadline + permitSignature to get ONE deposit transaction. Without a permit you get two transactions (approve, then deposit). Returns an UNSIGNED transaction {to, data, value, chainId} on Base; nothing happens until you sign it with your own wallet and broadcast it. Liquid never holds keys or funds. | read | false | unknown |
| stocks_buy_quote Free. Preview buying the tokenized stock basket: shares you would get and the fee for a USDC amount (USDC 6 decimals: "2000000" = $2). | read | false | unknown |
| stocks_create_vault Free. Opens your own vault for the tokenized US stock basket (NVDA, META, AAPL, GOOGL), controlled only by you. Returns an UNSIGNED transaction {to, data, value, chainId} on Base; nothing happens until you sign it with your own wallet and broadcast it. Liquid never holds keys or funds. After it confirms, find the vault with stocks_portfolio. | write | true | unknown |
| stocks_portfolio Free. Everything an address owns in the tokenized stock basket: each vault, its shares and current USD value. | unknown | unknown | unknown |
| stocks_publish_prepare Returns the x402 payment request to publish a live, shareable portfolio page for a vault for 24 hours ($0.01 USDC on Base or Polygon). Pay it with your own x402 client. This tool does not pay. | write | true | unknown |
| stocks_rebalance Free. Brings your vault back to its target weights (check stocks_vault: rebalanceNeeded). Returns an UNSIGNED transaction {to, data, value, chainId} on Base; nothing happens until you sign it with your own wallet and broadcast it. Liquid never holds keys or funds. | read | false | unknown |
| stocks_sell Free. Cash out: redeem basket shares to USDC, or take the raw stock tokens in-kind (works any block, no vault needed, anyone holding shares can sell). Returns an UNSIGNED transaction {to, data, value, chainId} on Base; nothing happens until you sign it with your own wallet and broadcast it. Liquid never holds keys or funds. | read | false | unknown |
| stocks_send Free. Transfer your tokenized stock basket shares to any wallet or another agent; they can hold, sell or forward them, no vault needed. Returns an UNSIGNED transaction {to, data, value, chainId} on Base; nothing happens until you sign it with your own wallet and broadcast it. Liquid never holds keys or funds. | write | true | unknown |
| stocks_set_weights Free. Sets your vault's target allocation across the 4 stocks in basis points (sum 10000), e.g. [4000, 3000, 2000, 1000]. Default is equal weight. Returns an UNSIGNED transaction {to, data, value, chainId} on Base; nothing happens until you sign it with your own wallet and broadcast it. Liquid never holds keys or funds. | write | true | unknown |
| stocks_signals_prepare Returns the x402 payment request for basket signals ($0.005 USDC on Base or Polygon): rebalancing signal, momentum and suggested weights for NVDA/META/AAPL/GOOGL in one call. Pay it with your own x402 client. This tool does not pay. | read | false | unknown |

| x402_check Free. Decode any x402 payment request (from a URL, a PAYMENT-REQUIRED header or a 402 body) into plain English with warnings, and optionally verify a signed payment (PAYMENT-SIGNATURE / X-PAYMENT header) the way a facilitator would: recipient, amount, time window, EIP-712 signature against the token's real domain, nonce reuse and balance. Every failed check comes with the fix. | unknown | unknown | unknown |
