# CornerStone MCP x402 Skill (for Agents)

This skill gives you (the agent) a set of tools to: create and manage Aptos and EVM wallets, check balances, and call x402-paid MCP tools (stock prediction, backtest, bank linking, agent/borrower scores). **Payment is automatic** — when a paid tool returns 402, the skill signs, verifies, settles, and retries transparently. You just call the tool; the result comes back.

## Quick-start workflow

Follow this sequence on first use, then skip to the tool you need:

1. **Check wallets** → call `get_wallet_addresses` (no args).
2. **If empty** → call `create_aptos_wallet` then `create_evm_wallet`.
3. **Fund** → call `credit_aptos_wallet` (Aptos faucet) and `fund_evm_wallet` (EVM faucet instructions).
4. **Tell the user** to whitelist the returned addresses at `https://arnstein.ch/flow.html`.
5. **Check balance** → call `balance_aptos` (must have USDC for predictions/backtests) and/or `balance_evm` (must have ETH for bank linking).
6. **Use paid tools** → `run_prediction`, `run_backtest`, `link_bank_account`, or score tools.

> **Important:** Paid tools will fail with a wallet/whitelist error if the address has not been funded and whitelisted. Always verify wallets and balances first.
