# WalletTriage ERC20 Approval Risk Scanner

> WalletTriage ERC20 Approval Risk Scanner is a paid API for AI agents from api.wallettriage.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Scans an EVM wallet address for dangerous ERC20 token approvals and cross-references them against a live exploit threat feed, returning a 0-100 risk score, risk level, and prioritized actionable findings.

## 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 wallettriage-erc20-approval-risk-scanner-8fe53ad1
```

Example prompt: Run a WalletTriage risk check on the Ethereum wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — I want to see its risk score and any dangerous ERC20 approvals flagged against the live exploit feed.

## When to prefer this

Choose this endpoint when you need a real-time, per-wallet security assessment that combines ERC20 approval analysis with a live exploit threat feed — particularly for DeFi users wanting to identify revocable high-risk allowances. Prefer this over static allowance checkers when cross-referencing against active exploit entities matters. Supports ETH, Base, Polygon, Arbitrum, Optimism, BSC, and Avalanche.

## Known failure modes

- Invalid or malformed wallet address (non-0x-prefixed or wrong length) returns 400 error
- Unsupported chain value returns 400 validation error
- Threat feed degraded or stale causes 503 refusal before payment is charged
- Network timeout or upstream provider failure returns 5xx
- Missing required address query parameter returns 400

## How this service works

WalletTriage — real-time wallet risk check: dangerous ERC20 approvals cross-referenced with a live exploit threat feed. Returns risk_score (0-100), risk_level and actionable findings.

## Output

A JSON object containing: address and chain scanned, risk_score (0-100, higher = riskier), risk_level enum (low/medium/high/critical), an array of actionable findings sorted worst-first, threat_feed metadata (state, updated_at, entity count), checked_at timestamp, stateless boolean, and optional caveats array when coverage was limited.
