CreditNexus x402 Agent Skill

Autonomous agent that **creates, funds, and uses** Aptos and EVM wallets, then calls x402-paid MCP tools (stock prediction, backtest, link_bank_account, agent/borrower scores). Handles payment flow (402 → pay → retry with `payment_payload`) with Aptos and Base. Supports **wallet attestation** (signing) for onboarding. Use when the user wants wallet setup, funding, balances, predictions, backtests, bank linking, scores, or token operations.
