CornerStone MCP x402 Skill (for Agents)
Skill that gives agents tools to call x402-protected MCP endpoints: stock prediction, backtest, bank linking, and agent/borrower scores. Payment is automatic — the skill handles 402 → sign → verify → settle → retry transparently. Supports wallet attestation (signing) for onboarding (POST /attest/aptos, /attest/evm).

balance_aptos(), balance_evm({ chain: "baseSepolia" }).
- Call paid tools:
run_prediction, run_backtest, link_bank_account, or score tools.
