## 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 wallet-risk-scorer-51d72312 -d '<json body>'
```

Example prompt: Before I set up autopay for wallet 0x4a3b...c7d2 on Base, can you give me its 0-100 activity risk score, flag any counterparty exposure or failed-call signals, and tell me what autopay and signing policy you'd recommend?

## When to prefer this

Use this endpoint when an AI agent needs a single, structured risk verdict on a Base wallet before authorizing a payment, setting up autopay, or granting signing permissions. Prefer this over raw transaction history endpoints when you need an actionable 0-100 score plus a policy recommendation rather than raw data, and over generic blockchain explorers when you need buyer-vocabulary risk framing suitable for autonomous spending decisions.

## Known failure modes

- Invalid or non-Base wallet address returns an error or empty result
- Wallet with no transaction history may produce a low-confidence or default score
- Payment not received or x402 payment failure results in 402 response
- D1 snapshot stale or unavailable may yield outdated risk assessment
- Rate limiting or worker timeout for high-traffic periods

## How this service works

Hosted wallet risk scorer for agents: exact buyer-vocabulary wallet risk score using transaction patterns, counterparty exposure, failed-call signals, protocol touchpoints, balance context, 0-100 activity risk, alerts, and recommended autopay/signing policy from refreshed D1 wallet history. Price 0.20 USDC on Base via x402. Demo: https://wallet-portfolio-history-mcp.mtree.workers.dev/demo/tools/wallet_risk_scorer. Contact: https://wallet-portfolio-history-mcp.mtree.workers.dev/contact.

## Output

Returns a 0-100 integer activity risk score for the queried Base wallet address, along with risk alerts (e.g. flagged counterparties, failed-call signals, suspicious protocol touchpoints), balance context summary, and a concrete recommended autopay and signing policy for autonomous agents to follow.
