Version History
- Improved and clarified documentation on wallet management, funding, and prerequisites for all tools. - Added detailed quick-start workflow and decision trees for common agent operations. - Explicit step-by-step tool reference for wallet, balance, and paid MCP actions. - Enhanced error handling documentation, including typical error patterns and recovery steps. - Now explicitly supports both Aptos and EVM chains for payment, with automatic 402-payment flow and transparent retry.
What This Skill Does
A set of MCP tools for agents that run stock predictions, backtests, bank linking, and agent/borrower credit scoring. Payment is handled automatically: when a paid tool returns a 402, the skill signs, settles, and retries without agent intervention. Supports Aptos and Base (EVM) wallets.
Agents call paid tools as if they were free — the x402 payment flow, wallet signing, and retry logic are fully abstracted away.
When to use it
- Running a 30-day stock price forecast for a specific ticker
- Backtesting a trading strategy over a historical date range
- Linking a bank account to raise a borrower credit score
- Checking an on-chain agent reputation score before a lending decision
- Querying borrower or agent scores by email in a marketplace context
Example Workflow
Here's how your AI assistant might use this skill in practice.
User asks: Run a 30-day stock prediction for AAPL
- 1Call get_wallet_addresses to check for existing Aptos and EVM wallets
- 2If Aptos wallet is missing, call create_aptos_wallet then credit_aptos_wallet
- 3Prompt the user to whitelist the Aptos address at https://arnstein.ch/flow.html
- 4Call balance_aptos to confirm sufficient USDC is available
- 5Call run_prediction({ symbol: "AAPL", horizon: 30 }) and return the forecast result
