## 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 base-sentinel-token-risk-analysis-4aa20f06
```

Example prompt: Can you run a full risk analysis on the token at address 0x4200000000000000000000000000000000000042 — I want to see the risk score, whether I should buy, hold, or avoid it, and what the on-chain metrics and social sentiment look like?

## When to prefer this

Use this endpoint when you need a holistic, multi-dimensional risk assessment of a specific token — combining on-chain analytics, social sentiment, and technical chart analysis in a single call. Prefer this over standalone price feeds or single-metric APIs when you need an AI-synthesized recommendation and risk reasoning rather than raw data alone.

## Known failure modes

- Invalid or malformed token address returns an error (non-0x-prefixed or wrong length)
- Token address not found on-chain results in empty or failed analysis
- Network or upstream data provider outage causes incomplete metrics
- Newly deployed tokens with insufficient on-chain history may return low-confidence scores
- Payment failure (insufficient USDC balance) blocks the request
