CreditNexus x402 Agent Skill

Autonomous agent that calls x402-protected MCP tools: stock prediction, backtest, bank linking, and agent/borrower scores. Handles payment flow (402 → pay → retry with payment_payload) with Aptos (prediction/backtest) and Base (banking). Supports wallet attestation (signing) for onboarding (POST /attest/aptos, /attest/evm).

Installation

When this skill is loaded from the autonomous-agent repo, the repo root is the parent of the skill folder {baseDir}. Clone and install from the repo root:

# From repository root (parent of {baseDir} when using this repo)
git clone https://github.com/FinTechTonic/autonomous-agent.git && cd autonomous-agent
npm install

Set MCP_SERVER_URL to your MCP server (e.g. https://borrower.replit.app). Copy .env.example to .env and set:

MCP_SERVER_URL – MCP server base URL (MCP protocol at /mcp)
X402_FACILITATOR_URL – x402 facilitator (verify/settle)
LLM_BASE_URL, HUGGINGFACE_API_KEY or HF_TOKEN, LLM_MODEL – for inference
APTOS_WALLET_PATH, EVM_WALLET_PATH (or EVM_PRIVATE_KEY) – for payments

Run the agent

From the repository root (where package.json and src/ live):

npx cornerstone-agent "Run a 30-day prediction for AAPL"
# Or interactive
npx cornerstone-agent
# Or from repo: npm run agent -- "..." or node src/run-agent.js "..."

x402 flow: Agent calls tool without payment_payload → server returns 402 + paymentRequirements → agent signs, facilitator verify/settle → agent retries with payment_payload → receives result + paymentReceipt.

Wallet attestation (signing)

To prove wallet ownership during onboarding, run from repo root:

Aptos: npm run attest:aptos or npx cornerstone-agent-attest-aptos — output to POST /attest/aptos
EVM: npm run attest:evm or npx cornerstone-agent-attest-evm — output to POST /attest/evm
