terminal

Comprehensive borrower score for any agent — derived from verified US bank-linking. Low-cost per query via x402.

Score opacity

Borrowers never see their own score. Only lenders receive the number when they query by wallet. This keeps the score focused on lending decisions and reduces gaming. How the Score Works →

How it works for Lenders

Reputation Score measures the agent's ability to transact using x402. Borrower score measures real borrower behavior. Both cost pennies. For a detailed breakdown of the score methodology, see How the Score Works.

integration_instructions

Integrate

Use the Lender Request API (REST) or the Model Context Protocol (MCP): GET /api/lender/scores/reputation and /api/lender/scores/borrower with your registered wallet in X-Lender-Wallet (or X-API-Key). Same credits and pay-per-query as MCP. Or install the npm package: npm install cornerstone-autonomous-agent

Decide

Make informed lending decisions backed by verifiable credit scores. You control the capital — we provide the data.

  • 0 Agent cannot use x402 — not on allowlist or no access.
  • 100 Agent can use x402 — base reputation (allowlisted).
  • 100+ Higher is better — base plus CornerStone component from verified bank linking.
api

Lender Request API

Lenders get score data via two REST endpoints. Authenticate with X-Lender-Wallet (your registered paying wallet) or X-API-Key. Same credits and pay-per-query as MCP.

link Endpoints

  • GET /api/lender/scores/reputation
  • GET /api/lender/scores/borrower

Query param: wallet=0x... (agent wallet).

key How to use

Send a GET request with the agent’s wallet in the query string. Include X-Lender-Wallet: <your-registered-wallet> or X-API-Key. On success you get the score; without credits you receive 402 Payment Required with payment details.

terminal Example request & response

Request

GET /api/lender/scores/borrower?wallet=0x742d35Cc6634C0532925a3b844Bc454e4438f44e
X-Lender-Wallet: 0xYourRegisteredPayingWallet

Response (200 OK)

{
  "score": "100+42",
  "payer": "0xYourRegisteredPayingWallet",
  "paymentReceipt": {
    "settled": false,
    "lender_credits": true
  }
}

Score 100 = base (allowlisted agent). 100+42 = base plus CornerStone component from verified US bank linking.
