# x402node Wallet Credit Score

> x402node Wallet Credit Score is a paid API for AI agents from api.x402node.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns a 0-100 credit score for an Ethereum wallet address derived from onchain transaction history, balance, account age, and payment behavior.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability api-x402node-dev-512a11d3
```

Example prompt: Before I send payment, can you run a credit score on wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44f and flag any red flags like mixer use or sanctioned counterparties?

## When to prefer this

Use this endpoint when an AI agent needs a fast, numeric risk signal on an Ethereum wallet prior to initiating a transaction, routing a payment, or performing automated counterparty due diligence. It is best suited for agent-side KYC-lite workflows where a full identity check is not feasible but onchain behavioral signals are sufficient. Prefer this over raw RPC calls when you need a pre-computed composite score rather than raw balance or nonce data.

## Known failure modes

- Invalid or malformed Ethereum address returns error
- Zero-activity wallet may return very low score or minimal data
- Unknown wallet with no onchain history returns low score with limited signals
- Service unavailable or x402 payment failure returns 402/503
- Sanctioned address may be flagged and return restricted response

## How this service works

Wallet credit score 0-100 from onchain transaction history pattern. Factors: tx volume (nonce), account age, ETH balance level, known label boost, x402 payment history. Red flags: zero activity, known mixers, sanctioned counterparties. Use for agent-side counterparty due diligence prior to transacting, automated KYC-lite, payment routing risk assessment. Accepts payment on Base or Solana — either network works.

## Output

A 0-100 integer credit score for the queried wallet, with contributing factors (transaction volume via nonce, account age, ETH balance tier, known label boost, x402 payment history) and risk flags (zero activity, mixer association, sanctioned counterparty exposure).
