## 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 x402-onchainexpat-com-e10d7aa6 -d '<json body>'
```

Example prompt: Can you check the safety of the token at address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — I want a unified risk score aggregated from multiple sources before I swap into it.

## When to prefer this

Choose this endpoint when you need a consolidated, multi-source token safety score rather than relying on a single provider's opinion. Especially useful for DeFi agents evaluating token trustworthiness before executing swaps, purchasing tokens, or recommending assets to users. Prefer this over single-source token metadata endpoints when risk aggregation across providers is the priority.

## Known failure modes

- Token address not found or unsupported chain — returns error or empty result
- Unsupported token format — malformed address returns validation error
- Upstream risk source unavailable — partial or degraded score returned
- Payment not confirmed — 402 payment required error if USDC payment not attached
- Rate limiting or timeout from underlying data providers

## How this service works

Pay-per-request AI, crypto, proxy, and utility APIs using x402 protocol

## Output

A unified token safety bundle that aggregates risk signals from multiple data sources into a single risk score, indicating how safe or risky a given token is. May include sub-scores or flags from individual risk providers, rug pull indicators, and an overall safety rating.
