Liquid Agent — Tokenized Stock Index
Agent-native tokenized-stock index on Base. Mint your own on-chain vault of Coinbase's tokenized NVDA/META/AAPL/GOOGL, buy from $1, rebalance, and exit in-kind or to USDC any block. No oracle, no token, fully self-custodial. Reads free; transactions return unsigned calldata the agent signs.
AgentCard object. It is an agent card in spirit rather than in schema — useful for
discovery, but an A2A client cannot assume it will parse.
no-protocolVersion
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

PAID $0.04 USDC via x402: the whole basket's rebalancing signal in one call — per-stock returns, volatility, RSI, trend, relative strength, correlation, and an inverse-vol suggested weightsBps. Optional ?vault= adds your current-vs-suggested drift.

PAID from $0.03 USDC via x402: an ERC-4337 paymaster for EntryPoint v0.8 on Base and Polygon (chainId: 137 for Polygon); pay the fee in USDC on Base or Polygon. On Solana, POST /v1/gas/solana {transaction} with our sponsor as fee payer and pay from $0.03 in Solana USDC. Standard ERC-7677 (pm_getPaymasterStubData / pm_getPaymasterData) at POST /v1/gas; plain EOAs POST {sender, calls} to the same /v1/gas (402 = quote, pay, sign, POST back the signed operation; EIP-7702; already delegated elsewhere: add redelegate:true, reversible). Any EntryPoint v0.8 smart account can bring its own operation: POST {userOperation} unsigned -> 402 -> pay -> sign -> POST back; we dry-run and submit it, no bundler. Price = max($0.03, 1.3× the op's gas cap), cap locked by signature.
